【Example】

 Embodiments of the present invention will be described below with reference to the drawings. First, the first embodiment shown in FIGS. 1 and 2 will be described. 1 is a main body side member to which a projecting portion 2 is screwed to an inner surface of a side plate of a furniture main body (not shown), and 3 is formed on an inner surface of a door 4. A door-side member in which the protruding portion 7 is screwed to the door 4 in a state where the main body 6 is fitted in the circular recess 5 formed therein, and the main body-side member 1 and the door-side member 3 are connected by a pin (not shown). The door side member 3 is rotatable with respect to the main body side member 1. Reference numeral 8 denotes a circular positioning projection provided at the tip of the projecting portion 7 of the door-side member 3, and a circular recess formed on the inner surface of the door 4 at the same time when the main body 6 is fitted into the recess 5. The door side member 3 is positioned by being fitted into the portion 9. The positioning convex portion 8 may be formed integrally with the overhanging portion 7, or may be formed as a separate component and fixed to the overhanging portion 7. Reference numeral 10 denotes a screw insertion hole formed in the positioning projection 8, and the screw 11 inserted in the screw insertion hole 10 is screwed into the door 4 to fix the door side member 3 to the door 4.

Next, the second embodiment shown in FIGS. 3 and 4 will be described. In contrast to the first embodiment, in which the positioning projection 8 is provided integrally with or fixed to the projecting portion 7, In the embodiment, the positioning convex member 13 having the flange portion 12 at the upper end is made as a separate component, and the projecting portion 7 of the door side member 3 is provided with a hole 14 into which the positioning convex member 13 is fitted. 14 is aligned with the circular concave portion 9 formed on the inner surface of the door side member 3, and in that state, the positioning convex member 13 is inserted into the hole 14 and the concave portion 9, and the screw inserted through the positioning convex member 13 is inserted. The screw 16 inserted into the hole 15 is screwed into the door 4 to fix the door-side member 3 to the door 4.

According to the above-mentioned two embodiments, the positioning of the door side member 3 can be performed by fitting the positioning convex portion 8 or the positioning convex member 13 into the circular concave portion 9 formed on the inner surface of the door 4. The door side member 3 can be fixed to the door 4 by screwing at that position.

By the way, although not shown in the drawings, the projecting portion 2 of the main body side member 1 is provided with a positioning convex portion or a positioning convex member similarly to the projecting portion 7 of the door side member 3, and the furniture main body is provided. A recess may be provided on the inner surface of the side plate to position the furniture body.

[0011]

[Effect of device]

 As described above, according to the present invention, the positioning of the door-side member relative to the door can be easily performed by fitting the positioning projection or the positioning projection member into the recess formed in the inner surface of the door.
