PURPOSE:To make compact the complex actuator by providing the cylinder chamber of cylinder type actuator in the shaft of rolling actuator. CONSTITUTION:Cylinder chamber 20 of cylinder type actuator 2, a port 17 and a guide member 16 are provided in the shaft 8 of rolling actuator 1. The piston rod 22 is coupled through the guide member 16 to the shaft 8 such that they can rotate integrally while slide axially. With such arrangement, the complex actuator can be made compact.
