This invention relates to a fluid pressure generation apparatus which can reduce noise and vibration, can improve durability, and yet has a simple construction and high assembling property. Said apparatus comprises a cylinder block (5), provided separately from the rotor (3) of a motor (4), a main spindle (6) at the center thereof and a plurality of cylinders (15) each of which includes a piston (16) slidably fitted thereto. A fitting hole (3a) is bored at the center of the rotor (3), and the cylinder block (5) is fitted and fixed to this fitting hole (3a). The rotor (3) is rotatably supported by a stationary member through the cylinder block (5) and the main spindle (6). A piston operation body (9) having a slope surface (9a), on which a shoe (22) held by the head portion (16a) of the piston (16) slides, is disposed on one of the sides in an axial direction of the cylinder block (5) and a valve plate (10) is disposed on the other side.
