Since the adjusting screw is loosely penetrated through the back plate of the main body arm and is screwed to the back plate of the mounting seat , by rotating the screw, the back plate portion of the main body arm comes into contact with the back plate of the mounting seat. Approach and separate from. This adjusting screw is screwed into the back plate of the mounting seat and the head being in contact on the back plate of the body arm, the tip is either rotatably concave cross-sectional profile of the spacer member that is furnished to the mounting seat When the adjustment screw is rotated, the head of the spacer member is attached to the back of the main body arm because the spacer member gently penetrates the mounting seat and the top is locked to the back plate of the main body arm. It moves integrally with the main body arm and the spacer member in contact with the plate. Therefore, even if the body arm is moved closer to or away from the mounting seat by rotating the adjustment screw,
The head of the adjusting screw does not protrude from the back plate of the main body arm.

As means for locking the spacer member to the back plate of the main body arm, for example, a method in which a projection is provided on the top of the spacer member and a locking hole into which the projection is fitted is provided on the back plate of the main body arm is adopted. Can be. The shape of the spacer member is not particularly limited as long as the cross-sectional shape is concave, but a concave member formed of a plate having an appropriate width, a bottomed cylindrical body, or the like is preferable.

Further, the mounting cup attached to the door side has a box shape having a structure in which the entire side wall is closed, so that the strength of the cup itself is increased, and excellent strength against torsion during use and force applied from the outside is exhibited. I do. Therefore, a slide hinge that can sufficiently withstand severe opening and closing of the door can be obtained.
