To provide a power transmission device of an engine for a vehicle capable of suppressing frequency of ratio change of a continuously variable transmission by supplying driving force when the engine rotates at low speed when engine generation torque is small and reducing whole width of the engine to increase degree of freedom for mounting and reduce cost.
A drive transmission device of the engine for the vehicle is provided with a start clutch for connecting rotation of a crank shaft 5 with the transmission smoothly when the vehicle starts, the hydrostatic continuously variable transmission 40 for performing speed change due to a difference in capacity between a swash plate hydraulic pump and a swash plate hydraulic motor and reducing speed of rotation of the crank shaft 5 to transmit to a drive wheel, and a slider 65 for changing an angle of a movable swash plate of the swash plate hydraulic motor by reciprocating a ball screw 64. The start clutch is a torque converter 33.
