2. Description of the Related Art A hinge which has recently been used is an elongated channel-shaped hinge element and a cup-shaped hinge element which are connected to each other so as to be relatively rotatable and relatively bendable through two connecting members extending over adjacent ends thereof. This is also combined with a groove-shaped intermediate member and a mounting plate. Normal,
This type of hinge is used when a door or lid is attached so as to be openable and closable.

[0003] When the door is mounted on the door mounting frame (opening for the door) using the above-mentioned hinge, as an example, an intermediate member is screwed to the back surface of the channel type hinge element in advance, and then the cup is mounted. The hinge element is screwed to the door, the mounting plate is screwed to the mounting frame, and the intermediate member in the channel hinge element is screwed to the mounting plate. The door mounted in this manner is held in a mounting state suitable for the door mounting frame by finely adjusting the channel type hinge element with respect to the intermediate member in two directions or three directions of front, rear, left, right, up and down. You. Therefore, in this type of hinge, an adjusting means mainly comprising a plurality of screws is interposed between the channel type hinge element and the intermediate member.

[0004] One of the important matters concerning the hinge is that the operation for mounting the door or the lid in a predetermined position can be performed rationally. More specifically, it is desirable that the door and the lid can be easily and accurately attached. A hinge capable of satisfying such a demand is disclosed in Japanese Patent Publication No. 5-7587.
No. 6 (International Publication No. WO86 / 02402) and Japanese Utility Model Laid-Open Publication No. 1-168678.

[0005] In these prior art hinges, the intermediate member held by the channel-type hinge element has a lock-type detachable structure with respect to the mounting plate. Therefore, when the channel-type hinge element is mounted on the mounting plate, the door is closed. It is only necessary to put the intermediate member on the mounting plate while pressing the mounting member against the mounting frame. Therefore, the installation of the door to the door mounting frame can be easily performed by one operator, and the subsequent fine adjustment can be accurately performed by one operator. Also, when the door is to be removed from the door mounting frame, this operation can be performed simply by operating the detachable operation lever to detach the intermediate member from the mounting plate.

Stabilize.

The spring member is made of a leaf spring and is thinly mounted by utilizing a gap or space between components. Since the spring material also serves as a holder for the attaching / detaching operation member, parts for that purpose can be omitted. Since the attachment / detachment operation member is a push-in operation type, there is no need to add a knob to the outer end of the operation member. As a synergistic effect, bulkiness of the structure can be prevented.

Since the push-in type operation member is a detachable operation member, the outer end portion of the operation member does not largely protrude out of one hinge element as compared with the tension operation type operation member. Therefore, it is possible to secure the appearance of the appearance.
