[Problem that the idea aims to solve]

However, in such conventional guide mechanisms, the protrusion of the slide body has a simple rectangular cross section. Because of the shape, the slide body slides and the slider in contact with the guide rail slides. When the slider body is bent backward in the sliding direction, the amount of bending of the slider will cause the sliding It is not absorbed at all on the protruding side of the body. Therefore, the bent part of the slider The slide body is pushed firmly between the protrusion of the slide body and the guide rail, and the slide body is smooth. There was a problem that it inhibited the slide. Also, as mentioned above, the slider can be partially removed. If the slider is curved or has a space inside, the slide movement During operation, the slider moves along the flat surface of the protrusion of the slide body toward the rear in the sliding direction. Frictional resistance between the slider and the guide rail because it tends to shift and deform irregularly There was a problem that the smooth sliding of the slide body was hindered due to changes in the slide body. .

[0006] The purpose of this invention is to absorb the deflection of the slider on the protrusion side of the slider, and to By regulating the form of deflection, the slide body can slide smoothly. An object of the present invention is to provide a guide mechanism for a slide body that can perform the following functions.

[0007]

[Means to solve the problem]

The slide body guide mechanism of the present invention is such that the protrusion of the slide body guides the guide rail. The guide groove is slidably guided within the guide groove, and the inner circumference of the protrusion is slidably guided within the guide groove. In a guide mechanism for a slide body in which a slider in contact with a surface is fitted, the protrusion The invention is characterized in that a recessed portion is provided on the outer circumferential surface of the slider for allowing the sliding member to deflect inward. be a sign.

[0008]

[Effect]

The guide mechanism of the slide body of the present invention is arranged on the outside of the protrusion of the slide body where the slider fits. By forming a depression on the circumferential surface and allowing the slider to bend due to the depression, , when the protrusion of the slide body slides in the guide groove of the guide rail, it touches the slider. The sliding part of the slide body is prevented from being pushed into the sliding part by the bent part. to make the sound smooth.

[0009] In addition, by regulating the form of deflection that occurs in the slider using the recessed portions, This suppresses large changes in sliding resistance caused by irregular deflection of the slider.
