Abstract

The objective of the present invention is to enable braking to be applied to a drive shaft when necessary without reducing the motor efficiency and while ensuring smooth rotation of the drive shaft. In this bent axis type axial piston motor the pressing force of a braking piston (92) is removed and the relative rotation of a separate plate (91) and a friction plate (90) is allowed when a drive shaft (20) is rotated via a cylinder block (30) due to the stroke movement of a piston rod (40) but when the separate plate (91) and the friction plate (90) are pressed against a braking force receiving plate (93) via the braking piston (92) the relative rotation of the separate plate (91) and the friction plate (90) is restricted thereby braking the drive shaft (20). In addition a restricting member (95) which restricts the movement of the braking force receiving plate (93) along the axis of the drive shaft (20) with respect to a casing (10) is interposed between the casing (10) and the braking force receiving plate (93).
