ABSTRACT:
A cylinder apparatus includes a cylinder body, support member, shaft, coned disc spring, air cylinder, and levers. The cylinder body is rotatably supported by a pair of frames. The support member is supported to be movable in a circumferential direction with respect to the cylinder body, and supports a suction head. The shaft is supported to be movable in an axial direction of the cylinder body. The coned disc spring biases the shaft in a first direction. The air cylinder moves the shaft in a second direction opposite to the first direction against an elastic force of the coned disc spring. The levers are swingably supported by the cylinder body and swing upon movement of the shaft to fix/release the support member with respect to the cylinder body.
