A clutch mechanism includes a first frictional engagement element that rotates integrally with a first rotary member, and a second frictional engagement element that rotates integrally with a second rotary member. A brake mechanism includes a third frictional engagement element that rotates integrally with a target rotary member that is one of the rotary members, and a fourth frictional engagement element fixed to a non-rotary member. A pressing mechanism includes a pressing part disposed between, in an axial direction, the frictional engagement elements and the frictional engagement elements, a driven part coupled to the pressing part so as to interlock therewith, and a linear motion mechanism that moves the driven part in the axial direction. The clutch mechanism and the brake mechanism are selectively engaged in accordance with whether the driven part is moved to an axial first side or to an axial second side by the linear motion mechanism.

Engagement device

A wheel support device includes: a planetary gear mechanism including a first rotating element rotatable about a rotation center axis, a second rotating element rotatable about the rotation center axis and configured to rotate in a reverse direction of the first rotating element, and a reaction force element configured to generate a reaction force against inputs from the first rotating element and the second rotating element; a first arm member including a first base end portion coupled to the first rotating element and a first tip end portion rotatably supporting a first wheel of a vehicle, and configured to rotate integrally with the first rotating element about the rotation center axis; and a second arm member including a second base end portion coupled to the second rotating element and a second tip end portion rotatably supporting a second wheel of the vehicle, and configured to rotate integrally with the second rotating element about the rotation center axis.
