形斜板式液圧モータ。[Claims for Utility Model Registration] (1) A casing, an output shaft rotatably supported by the casing, a cylinder block having a plurality of cylinders and rotating integrally with the output shaft, and a cylinder block having a plurality of cylinders that rotates integrally with the output shaft; a movably inserted piston;
A sliding member provided on each piston, a swash plate fixed in the casing so that each sliding member slides on one side, and a swash plate for supplying and discharging pressure oil into each cylinder. In a swash plate type hydraulic motor comprising a valve plate, an annular engagement surface is provided on the other end surface of the swash plate, and an annular engagement surface is provided between the other end surface of the swash plate and the casing. A swash plate type hydraulic motor with a built-in brake, characterized in that a brake device is installed to brake the rotation of the output shaft through frictional engagement. (2) The brake device includes a brake piston that is slidably provided between the casing and the other end surface of the swash plate, and a connection between the swash plate and the output shaft between the brake piston and the engagement surface. a friction plate provided on each side, a spring that always biases the brake piston toward the braking side, and a hydraulic pressure provided between the brake piston and the swash plate to displace the brake piston toward the brake release side. 1. A swash plate type hydraulic motor with a built-in brake as set forth in claim (1) of the utility model registration, comprising: a chamber;
