Abstract
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.
Claims14
A bearing support structure for an actuator, for supporting a bearing at a sliding portion between a displacement member displaceable in an axial direction of a main actuator body and a guide section of said main actuator body, said bearing support structure comprising:
- a bearing having a sliding surface that abuts against said guide section;
- and
- a bearing support section provided on said displacement member, said bearing support section retaining said bearing between said bearing support section and said guide section, both end surfaces of said bearing being disposed in said axial direction of said bearing, only one of said end surfaces abutting against said displacement member when said displacement member is displaced,
- wherein said one end surface of said bearing is pressed by said bearing support section during a state in which said bearing abuts against said guide section and said bearing is displaced integrally with said displacement member, when said displacement member is displaced in said axial direction along said guide section.
