A passage (4a) connects one of the pressure chambers (R3A, R3B) partitioned by a free piston (5) and the first operating chamber (R1) under a second flow resistance. A passage (4b) connects the other of the pressure chambers (R3A, R3B) and the second operating chamber (R2) under a third flow resistance.
