(Prior Art) A hinge in which a base body and a rotating body are rotatably connected to each other by a plurality of link arms so as to be rotatably openable and closable, and the base body is attached to a fixture fixed to a fixed side,
For example, as shown in Japanese Utility Model Application Publication No. 58-159368, a base body, on which a rotating body is attached to a door body, is attached to a fixture that is previously fixed to the furniture body.

The above fixture is attached via a fixed base body that is screwed to the furniture body and a long hole formed in this fixed base body along the left and right direction (up and down direction when fixed to the side panel of the furniture body). It consists of a movable base body that is attached by tightening screws, and the movable base body can be moved in the left-right direction along an elongated hole with respect to the fixed base body. When the base body is attached to the fixture consisting of the fixed base body and the movable base body, the height position of the door body relative to the furniture body can be adjusted by moving the movable base body in the vertical direction. ing.

Further, as a structure in which a movable base body is connected to a fixed base body and a base body is connected to this movable base body, for example, a structure described in Japanese Utility Model Application Publication No. 176568/1983 is also known. This structure engages the tapered end surfaces formed on both ends of the fixed base body with the tapered surfaces formed on both ends of the movable base body, and moves into a pair of inclined holes formed on the fixed base body. A pair of inclined protrusions formed on the base body are inserted and fitted, and an adjustment screw is screwed from the long hole of the movable base body into the screw hole of the fixed base body to connect the movable base body to the fixed base body. The protrusions formed at the ends of both side plates of the base body are engaged by sliding with the flanges on both sides formed at the ends of the base body, and the tips of the adjustment screws screwed onto the ends of this base body are engaged. The structure is such that the base body is connected to the movable base body by pressing into a recess formed in a surface portion between the flanges of the movable base body.

(Problem to be solved by the invention) In the structure described in the above-mentioned Japanese Utility Model Publication No. 58-159368, the movable base body is attached to the fixed base plate only by tightening the mounting screws. Even if the mounting screws become slightly loosened due to the weight of the door body and the opening/closing operation of the door, the movable base body will move downward, causing a shift in the mounting position of the door body relative to the furniture body, and the mounting screws may become loose. When loosening the tightening and sliding the movable base, it is difficult to slide both the front and rear ends of the movable base parallel to each other, and the angle shifts relative to the fixed base.

In addition, in the structure described in Japanese Utility Model Application Publication No. 57-176568, the movable base body has a mutual relationship between the tapered end surfaces and the tapered surfaces of both sides formed on each side, and the inclined protrusion and inclined hole. Since the movable base body slides and moves downward even if the adjusting screw becomes slightly loosened due to the weight of the door body and the opening/closing operation of the door body, the movable base body will slide and move downward. , the installation position of the door body relative to the furniture body is misaligned, and the base body is attached to the movable base body with the protrusion of the base body slidably engaged with the flange of the movable base body, and the tip of the adjustment screw of the base body Since it is attached by pressing into the recess of the movable base, even if this adjustment screw is loosened, the base will slide back and forth from the movable base.
There is a problem in that the mounting position of the door body relative to the furniture body is misaligned.

The present invention was developed in view of the above-mentioned problems, and it is possible to securely fix the fixed base body and the movable base body of the fixture, and the movable base body and the base body of the fixture in a mutually engaged state. , the movable base body and base body do not move in the left-right direction or front-back direction, and the movable base body and base body can easily move even if the screws become slightly loosened due to the weight of the door body and the opening/closing operation of the door body. Therefore, it is possible to prevent the installation position of the door body from shifting with respect to the furniture body, and when making adjustments, the movable base body can be easily and easily slid in parallel to the fixed base body. , you can set the adjustment precisely,
Therefore, it is an object of the present invention to provide a hinge that ensures reliable connection and fixation between a fixture and a base body and that allows easy adjustment thereof.
