Abstract:
1. A four-wheel-drive all terrain vehicle, comprising: an engine for driving the vehicle; a power transmission path including an upstream path and a downstream paths, the power transmission path being configured to provide front-wheel-drive through which a drive force from the engine is transmitted to front wheels through the upstream path and the downstream path in this order; and a drive force disconnecting device provided in the power transmission path between the upstream path and the downstream path, the drive force disconnecting device being configured to connect and disconnect transmission of the drive force from the engine, the drive force disconnecting device including: wherein the drive force disconnecting device is adapted to stop transmission of the rotation of the drive-side rotary member to the driven-side rotary member by means of the torque transmission member when the vehicle is in four-wheel drive and the rotation of the drive-side rotary member is braked; and wherein the braking mechanism is configured to switch to the braked state to allow the torque transmission member to be placed in torque transmission state in which the torque transmission member transmits the rotation of the drive-side rotary member to the driven-side rotary member, and to switch to the non-braked state to allow the torque transmission member to be placed in a torque transmission release state in which the torque transmission member does not transmit the rotation of the drive-side rotary member to the driven-side rotary member.
