アクチュエータ
Document Type and Number:
Japanese Patent JP7248959
Kind Code:
B2
Abstract:
An actuator (10) has a body (18) and a slider (40). A groove (90) for the body-side rail is formed in the side wall portions (22, 23) constituting the body (18). On the other hand, the slider (40) is formed with a groove (128) for the slider side rail. The body-side guide rail (100) and the slider-side guide rail (140) are installed in the body-side rail groove (90) and the slider-side rail groove (128). Circular arc grooves (152, 154) are formed as ball grooves by the body-side ball receiving portions (114, 116) of the body-side guide rail (100) and the slider-side ball receiving portions (146, 148) of the slider-side guide rail (140). Thus, the actuator can achieve miniaturization and weight reduction.
