[Problem] An object is to provide a front suspension device for a vehicle that, when a collision load acts on a suspension arm, is capable of reducing the detachment amount of a subframe mounting portion on the rear side from a vehicle body, absorbing collision load energy, and thereby reducing an input to a rear axially supporting portion for a subframe.[Means for Solution] The front suspension device for a vehicle is characterized by including: a subframe SF; a suspension arm 10 having an outer end on which a front wheel is pivotally supported, and an inner end pivotally supported with respect to the subframe; a subframe mounting portion 13A for mounting the subframe SF to a vehicle body 2 through a fastener 17 from below on the rear side relative to a front-wheel axially supporting portion of the suspension arm 10; and an upward bend inducing portion 60 for bending the suspension arm 10 upward when a suspension arm frontal collision load is input via the front wheel to the suspension arm 10.

A gear shift operation device for a vehicle to which a multiple-stage automatic transmission is mounted, is provided. By a control lever being manually operated in a range switchable mode, a range position is switched at least between a D-range where automatic transmission is performed and an R-range, and by the control lever being manually operated in a manual transmission mode, a gear change is performed. An operation reaction force when the control lever is manually operated is set larger when the gear change is performed in the manual transmission mode than when the range position is switched in the range switchable mode.

In the engine compartment, an engine, a generator using the engine as a power source, a motor for driving the vehicle, and a gear box are arranged in alignment in a vehicle width direction. The first high-voltage equipment is vertically provided on a generating unit that includes the engine and the generator. The second high-voltage equipment is vertically provided on a drive unit that includes the motor and the gear box. The first high-voltage equipment and the second high-voltage equipment are coupled by a coupling member that extends substantially horizontally in the vehicle width direction and supports the high-voltage equipment against a falling load directed from one thereof toward the other.

[Task] To provide a front body structure of a vehicle that can reduce the vertical displacement of top portions 4b of strut towers and damp vibrations in the torsional direction between the top portions 4b of the strut towers and a cowl member 6 without increasing the weight of the vehicle body.[Solution] A front body structure of a vehicle includes a dash panel 1 that separates a vehicle interior R from an engine room E, a pair of left and right front side frames 2 that extend from left and right end portions of the dash panel 1, a pair of left and right strut towers 4 that support the upper portions of dampers of a suspension device in the outer portions in the vehicle width direction of the front side frames 2, in which a first coupling member 30 that couples the cowl member 6 to the strut towers 4 is provided, the first coupling member has a reinforced layer portion made of fiber reinforced plastic in which fibers are impregnated with a synthetic resin material, and the fibers of the reinforced layer portion are oriented so that the fibers extending in a longitudinal direction are more than the fibers extending in directions other than the longitudinal direction.

[Task] To provide a body structure of a vehicle that achieves a vibration damping function regardless of an input portion. [Solution] A body structure of a vehicle includes a second coupling member 40 made of fiber reinforced plastic including fibers impregnated with synthetic resin and a pair of rear fixing members 60 that have a bending rigidity higher than the second coupling member 40 and fix both end portions in the longitudinal direction of the second coupling member to a vehicle body, in which boundary portions B1 between the pair of fixing members 60 and the second coupling member 40 are formed in both end portions in the longitudinal direction of the second coupling member 40, and a distance D1 between the boundary portions on the rear side is different from a distance D2 between the boundary portions on the front side in the boundary portions B1 that extend along neutral axes A defined by the lines of intersection between the neutral plane of bending moments of the second coupling member 40 and the lateral cross sections of the second coupling member 40 when a bending load is input through the pair of rear fixing members 60 to the second coupling member 40.

A control device for controlling an engine provided with a fuel pump including a pressurizing chamber, a plunger inserted into the pressurizing chamber and which changes a volume of the pressurizing chamber, and an on-off valve configured to open and close a suction port, is provided. When a pressurizing cycle consists of a period of pressurizing stroke in which the volume of the pressurizing chamber is reduced to allow fuel to be pressurized and a period of suction stroke in which the volume of the pressurizing chamber is increased to allow fuel to be drawn into the pressurizing chamber, , a closing cycle of the on-off valve is controlled so that a ratio of the closing cycle to the pressurizing cycle becomes smaller in a second combustion mode where a partial compression-ignition combustion is performed than in a first combustion mode where SI combustion is performed.

The present disclosure keeps a topcoat film 3 from having a dent 6 in a portion of its surface corresponding to a pinhole 4 of a resin molded product 1. A method of the present disclosure includes: applying an undercoat material to a resin molded product 1 to form an undercoat film 2; applying a topcoat material to a surface of the undercoat film 2 to form a topcoat film 3; and thermally curing the topcoat film 3. A coating material that contains a base resin having a larger volume expansion coefficient than the resin molded product 1 and a granular filler having a smaller volume expansion coefficient than the base resin and a number-average particle size of 2 µm or more to 12 µm or less is used as the undercoat material.
