A slider is displaceable in an axial direction on guide sections of a cylinder tube through a guide mechanism. A first elastic member is interposed between a first bearing support member of the guide mechanism and one retaining section of the slider. A bearing installed in the first bearing support member, is pressed continuously toward the guide section. A second bearing support member is installed via a second elastic member between the guide section and another retaining section of the slider. A bearing provided on the second bearing support member is pressed toward the guide section by means of a resilient force of the second elastic member.

Guide mechanism for cylinder apparatus

A coupler is provided inside an engaging hole of a piston yoke, which is connected to pistons. A slider is installed on an upper portion of the coupler through a coupler-insertion hole. An engaging member, provided at a lower portion of the coupler, is inserted into the engaging hole so as to be displaceable by a slight amount in the widthwise direction of a cylinder tube. The coupler is inserted into the coupler-insertion hole of the slider, so that the coupler-insertion hole is slidable with respect to curved surface sections of the coupler.

Displacement difference-absorbing mechanism for cylinder apparatus

A slider is displaceable in an axial direction on guide sections of a cylinder tube. Bearings are installed with the slider, so that the bearings are opposed to the guide sections. Bearings are also installed on first and second bearing support members, which are provided respectively at retaining sections of the slider. When the slider is displaced in the axial direction along the cylinder tube, only one end surface of one of the flange sections of the bearing is pressed, depending on the displacement direction of the slider, in order to effect displacement in an integrated manner.

Bearing support structure for actuator

Linear actuator

Belt guide members guide an upper belt and a lower belt for closing a slit of a cylinder tube. Belt holder sections for the upper belt and belt separators for separating the upper belt and the lower belt from each other are integrally formed in the belt guide members. Bearings for positioning a slider are disposed to engage with the belt guide members.
