It is intended to provide a swash plate type continuously variable transmission capable of automatically affording a lock-up state in which second distributing valves are stopped at their stroke mid-point to cut off motor ports when a motor swash plate stands upright, even without using any special interlocking mechanism. Second distributing valves for bringing motor ports of motor cylinder bores into communication with a high-pressure oil path and a low-pressure oil path selectively in an alternate manner are arranged in parallel with the axis X of a cylinder block; a valve swash plate for reciprocating the second distributing valves is integrally combined with a motor swash plate on the same slant plane; and the motor ports are formed so as to be controlled selectively by the second distributing valves at respective positions 90° out of phase in the in circumferential direction of the cylinder block 4 with respect to the corresponding motor cylinder bores, the second distributing valves being stopped at their stroke mid-points when the motor swash plate stands upright. In a swash plate type hydraulic unit for use as a swash plate type oil-hydraulic pump or motor, it is intended to attain the reduction in redial size of the hydraulic unit while ensuring a sufficient plunger stroke.0
