- the leaf spring member is inserted into the movable shaft so as to be non-rotatable and movable in the axial direction, the force rotating together with the movable shaft is
- the bracket can move in the axial direction, but does not rotate even if the movable shaft rotates. Since the leaf spring member and the second bracket are pressed against each other and are in contact with each other, the leaf spring member and the second bracket are pressed against each other by the rotation of the leaf spring member due to the rotation of the movable shaft. When they are in contact with each other, they rotate relative to each other, so that a rotational torque is generated by mutual frictional force. In particular, since the leaf spring member is formed to be curved and has a projection having a flat contact surface with the second bracket at the curved top, the leaf spring member is compressed when rotating while sliding on the second bracket. Since the radius and the urging force act, the frictional force increases and a large rotational torque is generated.
- the opening and closing of one member and the other member can be controlled by this rotational torque.
- a rotational torque is generated between the leaf spring member and the second bracket due to a mutual frictional force. Opening, closing, stopping and holding can be performed.
- the contact surface of the projection of the leaf spring member with the second bracket is flat, the contact area can be increased and the rotational torque can be increased, and the abrasion of the projection and the second bracket is reduced and the durability is reduced. Can be improved.

- the spring member and the friction member and the second bracket are pressed against each other to rotate relative to each other, so that a rotational torque is generated by mutual frictional force.
- the rotational torque due to the frictional force is generated between the leaf spring member and the second bracket and between the frictional member and the second bracket, so that the rotational torque increases.
- the leaf spring member is formed in a curved shape, and the top of the curved portion is provided with a projection having a flat contact surface with the second bracket. Therefore, when the leaf spring member is brought into sliding contact with the second bracket and rotated, the leaf spring member is compressed. As the biasing force acts, the frictional force increases and a large rotational torque is generated.

- a recess or the like a recess, hole or notch
- the rotational torque is generated by the mutual frictional force, and the curved leaf spring member is compressed via the projection to bend, and the rotational torque is generated by the urging force. This is because, when the second bracket falls, the bent portion of the leaf spring member becomes smaller and the generated pressing force (biasing force) becomes smaller.

- the position of the click feeling is set, for example, to the closing position of the lid, it becomes possible to generate a force in the closing direction when the lid is closed.
- a latch mechanism for keeping the body closed is not required, so that compactness can be measured and the degree of freedom in design can be increased. Further, at the full open position of 180 °, operability is improved without generating a tactile sensation.
- FIG. 19 is a front view showing a hinge device according to a fourth embodiment of the present invention.
- spring washers 2 are provided on both sides of a second bracket 6 so as to sandwich the second bracket, and the other components are the same as those in the first embodiment.
- the same reference numerals are given and other detailed description is omitted.
- the spring washers 2 are present on both sides of the second bracket 6, it is possible to generate rotational torque due to mutual frictional forces on both sides of the second bracket 6, and it is possible to generate a large rotational torque. it can.
- a click feeling is generated only between the spring washer 2 existing on one side of the second bracket 6 and a click feeling is generated only between the spring washer 2 existing on both sides of the second bracket 6.
- the position of the tactile sensation generated between the spring washer 2 present on both sides of the second bracket 6 is the same depending on the position of the concave portion of the second bracket 6 and the position of the projection 2b of the spring washer 2. And can be different. Therefore, generation of a click feeling can be selectively expanded.
- the embodiments do not limit the present invention.
- Various changes can be made to the present invention without departing from the scope of the invention.
- the present invention can be implemented even if the friction washer 3 as a friction member is deleted.
- the concave portion of the second bracket may be eliminated. In that case, the function of the hinge device (opening / closing / stopping and holding) is performed without a click feeling.
- the hinge device according to the present invention is suitable for a hinge device that connects one member and the other member so as to be openable and closable, and is particularly suitable for a small OA device such as a notebook computer or a mobile phone.
- a small OA device such as a notebook computer or a mobile phone.
- Device that opens and closes the main body and the lid in portable devices and portable terminal devices And a hinge device for opening and closing the toilet body, the toilet seat, and the lid.
