As shown in FIG. 6, cam surfaces 31 and 41 are engaged with each other at 180 degrees to form a cam curve, and the cam surfaces 41 are provided with locking grooves 41a to which the cam vertices are locked at a 90 degree rotational position. have.

The shaft 20 is assembled with a key locker 50 for releasing the bite of the movable cam 30 and the sliding cam 40 that are engaged with each other, the second cam 104 on the movable cam 30. When the key is closed, the rotation of the key locker 50 is suppressed, and when the shaft 102 is pressed, a stopper means is provided which is separated from the key locker 50.

In this embodiment, the stopper means is composed of a locking jaw 32 protruding integrally in the axial direction to the inner diameter portion of the movable cam 30.

The key locker 50 is slidably inserted into the small diameter portion 23 of the shaft 20 and is configured to be integrally rotatable to the shaft 20 and the sliding cam 40.

As shown in FIG. 7, the key locker 50 extends from the cylindrical portion 51 inserted into the shaft 20, and extends from the cylindrical portion 51 to be able to slide in the key groove 42 of the sliding cam 40. It consists of the key part 52 to be fitted.

The sliding cam 40 is assembled to the cam housing 60, the cam housing 60 is fixed to the second body 104 side. One end of the cam housing 60 is fixed to the distal end of the small diameter portion 23 of the shaft 20, and the sliding cam 40 is assembled in the cam housing 60 so as to be linearly movable.

The key locker 50 is pushed toward the movable cam 30 by the compression repulsion force of the inner spring 70. The inner spring 70 is inserted into the small diameter portion 23 of the shaft 20 so that one end is in contact with the key locker 50 and the other end is in contact with the inner wall of the cam housing 60.

Reference numerals 92 and 94 are 'washers'.

The operation of this embodiment configured as described above will be described.

First, the assembled state of the auto-click hinge 10 in the state in which the second body 104 is closed to the first body 102 (phone closed state) is shown in FIG. That is, as shown in (a) of FIG. 8, the main spring 80 is pushing the sliding cam 40 toward the movable cam 30 by the compression repulsion force, and the key locker 50 is inner as shown in FIG. 2. It is the state which is pushed toward the movable cam 30 side by the spring 70. As shown in FIG.

At this time, the movable cam 30 is fixed to the first body 102, the cam housing 60 is fixed to the second body 104.

Further, in the phone closed state, the tip portion of the key portion 52 of the key locker 50 is engaged with the locking jaw 32 of the movable cam 30 (see also the cam line in FIG. 9).

Therefore, the movable cam 30 and the sliding cam 40 are generated by the sliding cam 40 under the force of the main spring 80, the force that the cam surfaces 31, 41 are mutually sliding to each other is generated sliding cam 40 The rotation force is applied in the opening direction of the EPON (the arrow direction in FIG. 1).
