PROBLEM TO BE SOLVED: To increase the degree of freedom of the layout of a fluid-pressure actuator in which a rod is fixed to a piston slidably fitted to a cylinder. SOLUTION: The axis L1 of the rod 76 fixed to the piston 75 and slidably guided by a guide member 77 is deviated from the axis L2 of the piston 75 slidably fitted to the cylinder 74. Accordingly, the degree of freedom of the arrangement of the fluid-pressure actuator 64 can be increased more than a case where the axis L1 of the rod 76 is aligned with the axis L2 of the piston 75. Also, since the piston 75 and the rod 76 formed separately from each other are joined to each other through an O-ring 82, the rod 76 can be moved relative to the piston 75 due to the deformation of the O-ring 82. Thus, the piston 75 can be smoothly operated by absorbing the displacement of the axis of the guide member 77 from the axis of the rod 76. COPYRIGHT: (C)2006,JPO&NCIPI
