[Problems] An object is to realize a park lock mechanism that contributes to miniaturization in the unit in which the motor and the drive shaft are arranged on separate axes.[Solutions] The unit includes the motor, the link shaft connected at the downstream side of the motor, and the park lock mechanism having the park gear provided on the shaft, the shaft being configured to rotate integrally with the rotor of the motor, the park pawl that engages with the park gear, and the park actuator that rotates the park pawl. The link shaft is positioned on the outer circumference of the motor. When viewed from the first orthogonal direction orthogonal to the axial direction of the link shaft, the link shaft and the park actuator each have a portion that overlaps with the motor. When viewed from the second orthogonal direction orthogonal to the axial direction and the first orthogonal direction, the park actuator has a portion that overlaps with the link shaft.

[Problems] To suppress both the deflection of the shaft during high-speed rotation and the vibration of the shaft when the applied load on the gear is large.[Solutions] A unit has: a rotating electric machine; a shaft connected at the downstream side of a rotor of the rotating electric machine; a gear connected at the downstream side of the shaft; a first bearing provided so as to be capable of supporting the shaft; a second bearing provided so as to be capable of supporting the shaft; and the damping and restricting member provided so as to be capable of supporting the shaft. In a radial direction view, the rotating electric machine is positioned between the first bearing and the second bearing. In the radial direction view, the second bearing is positioned between the gear and the rotating electric machine. In the radial direction view, the gear is positioned between the second bearing and the damping and restricting member. The damping and restricting member is set such that the allowable movement amount of the shaft in the radial direction at a corresponding support position is larger than allowable movement amounts of the first bearing and the second bearing.

[PROBLEM] To control the motor so as to conform to the target exercise intensity of the driver without the driver having to wear a heart rate detection sensor or the like.[SOLUTION] The vehicle, in which the drive wheel is driven by the motive force input by the driver and the motive force input from the motor, includes: a torque sensor configured to detect a torque of the motive force input by the driver; an input speed sensor configured to detect an input speed of the motive force input by the driver; and a controller configured to control the motor, wherein the controller is configured to: calculate a work amount of the driver based on the torque detected by the torque sensor and the input speed detected by the input speed sensor, and estimate an oxygen intake amount of the driver from the work amount; estimate a maximum oxygen intake amount of the driver from a physical parameter of the driver; and control the motor such that an exercise intensity calculated from the oxygen intake amount and the maximum oxygen intake amount approaches a target exercise intensity of the driver.

[Problem] To reduce the time during which both a rotational torque and an actuator thrust act on a bearing. [Solution] This transmission device comprises: a first planetary gear mechanism; a second planetary gear mechanism; a first fastening mechanism; a second fastening mechanism; and a third fastening mechanism. The third fastening mechanism includes: a pressing part that fastens a fastening element; a spring that biases the pressing part in a fastening direction; an actuator that generates thrust in a release direction and that releases the fastening element by using the thrust to displace the pressing part in the release direction; and a bearing that, when the fastening element is to be released, receives the load of the spring compressed by the thrust. In a first speed-changing step, the transmission device fastens the first fastening mechanism and releases the second fastening mechanism and the third fastening mechanism, and in a second speed-changing step, the transmission device fastens the second fastening mechanism and releases the first fastening mechanism and the third fastening mechanism. The first speed-changing step is selected during emergency travel, which requires a larger driving force than during a normal start.
