In a bent axis type axial piston motor, so as to smoothly rotate a drive shaft without lowering motor efficiency and brake the drive shaft if necessary, when the drive shaft is rotated through a cylinder block by causing piston rods to reciprocate, relative rotation between separate plates and friction plates is allowed by removing a pressing force applied by a braking piston, and when the separate plates and the friction plates are pushed to a brake force receiving plate by the braking piston, relative rotation between the separate plates and the friction plates is restrained and thus the drive shaft is braked. Restriction members are disposed between a casing and the brake force receiving plate so as to restrain the brake force receiving plate from moving relative to the casing along the axis of the drive shaft.
