1. A cuff unit configured to restrain and press an object that has a rod shape, the cuff unit comprising:
a first wall and a second wall that each have a flat plate shape, are separated from and face to each other, and are arranged to receive the object having the rod shape between the first wall and the second wall when the cuff unit is used, the second wall being translationally movable in a first direction in which the second wall relatively approaches to the first wall or separates from the first wall;
a pressing fluid bag that is provided on a surface of the first wall on a side facing the object and that receives supply of a fluid from outside to inflate and press the object;
a restraining fluid bag that is provided on a surface of the second wall on a side facing the object and that receives supply of a fluid from outside to inflate along a periphery of the object;
a third wall that has a flat plate shape, is separated from and faces a surface of the second wall on a side opposite to the first wall;
a support wall that extends in the first direction in a manner separated from the second wall and integrally connects sides of the first wall and the third wall which face to each other, the first wall, the third wall and the support wall constituting an integral outer frame of the cuff unit; and
an actuator fluid bag that is provided between the second wall and the third wall and that receives supply of a fluid from outside to expand; and
a pressurizing pump that supplies the fluid to the actuator fluid bag to expand, and an exhaust valve that discharges the fluid from the actuator fluid bag to contract, such that the second wall moves translationally in the first direction between the first wall and the third wall.
