A straddled vehicle 1 includes a head tube 3, a front fork 7, a front wheel 8, a left shroud 31L, a right shroud 31R, a radiator 11, and a radiator grille 20. The radiator 11 is located rearward of the front fork 7 and between the left shroud 31L and the right shroud 31R. The radiator grille 20 is located rearward of the front fork 7, between the left shroud 31L and the right shroud 31R, and forward of the radiator 11. The radiator grille 20 includes a plurality of louvers 40. The louvers 40 are lined in a transverse direction Y. It is assumed that, among all the louvers 40, a louver 40 closest to a vehicle center plane C is a first louver 41. The first louver 41 projects more forward than the louvers 40 other than the first louver 41.

A leaning vehicle capable of controlling a driving force of a left front wheel and a driving force of a right front wheel independently of each other. A leaning vehicle (1) includes: a vehicle body frame (10) including a head pipe (12); a left front wheel (20L); a right front wheel (20R); a steering shaft (31) rotatable left and right together with the left front wheel (20L) and the right front wheel (20R); a handle bar (30); a link mechanism (40) that links together the vehicle body frame (10), the left front wheel (20L) and the right front wheel (20R) so that the vehicle body frame (10), the left front wheel (20L) and the right front wheel (20R) can tilt together; a left in-wheel motor (50L) provided on the left front wheel (20L); and a right in-wheel motor (50R) provided on the right front wheel (20R).

A marine vessel maneuvering system (102) includes a marine propulsion unit (1) including an electric motor (12), an input (2) configured to input a neutral command (E1) to stop the electric motor and configured to input a drive command (E2, E3) to drive the electric motor, a start switch (31) configured to switch a stopped state in which the electric motor is not driven to a ready-to-be-driven state in which the electric motor is ready to be driven, and a controller (7) configured or programmed to perform a control to switch the stopped state to the ready-to-be-driven state upon a user operating the start switch when a main power supply that controls a power supply to an on-board device (D) of a hull (101) is in an on state, the neutral command is being input to the input, and a marine vessel is in the stopped state.

A sheave for a continuously variable transmission (100) includes: a boss member (110) being made of a first metal material; and a sheave member (120) that is made of a second metal material which is a different kind from the first metal material, the sheave member (120) including a sheave surface (121) and a rear surface (122). The sheave member is mounted on an attachment region (AR) being a part of an outer peripheral surface (110os) of the boss member (110) via plastic flow coupling. The attachment region has a stepped shape that includes a first region (R1) having a relatively small diameter, a second region (R2) having a relatively large diameter, and a step surface (SS1) located at a boundary between the first region and the second region. The first region, the step surface, and the second region are disposed in this order from the sheave surface side toward the rear surface side, and the sheave member abuts with the step surface.

A hydraulic tensioner includes a tensioner body having a through hole formed therein, a bottomed cylindrical plunger inserted into the through hole of the tensioner body so that the cylindrical plunger is movable in an axial direction of the through hole, a cylindrical inner sleeve inserted inside the plunger, and a tensioner cap attached to one end of the tensioner body and having a first surface in contact with a proximal end of the inner sleeve. A first hydraulic chamber is formed between the inner sleeve and the plunger, and a second hydraulic chamber that stores oil to be supplied to the first hydraulic chamber is formed inside the inner sleeve. The first surface of the tensioner cap has a plurality of grooves that each connect between outside of the inner sleeve in a radial direction and the second hydraulic chamber.
