Claims

[Claims for Utility Model Registration] (1) A guide rail, a sliding body guided in the longitudinal direction of the guide rail by the guide rail, and a fluid pressure cylinder that slides the sliding body along the guide rail. In the feed unit device, the fluid pressure cylinder is disposed along the longitudinal direction of the guide rail between the lower surface of the guide rail and the upper surface of the sliding body within the width of the guide rail, and A feed unit device characterized in that a cylinder tube of the fluid pressure cylinder is fixed to one of the sliding body and the guide rail, and a piston shaft of the fluid pressure cylinder is fixed to the other. (2) A cylinder tube mounting groove for fixing the cylinder tube to the guide rail or the sliding body, and a cylinder tube mounting groove continuous to the cylinder tube mounting groove,
a groove that allows the piston shaft to operate;
The cylinder tube mounting groove has a larger cross-sectional area in a direction perpendicular to the longitudinal direction of the groove than the groove that allows the operation of the piston shaft, and a stepped portion is formed between both grooves, and this stepped portion allows the cylinder tube to be attached to the cylinder tube. The feed unit device according to claim 1, wherein the front end of the feed unit is restrained.
