- an engagement convex portion 66 is formed at a predetermined position of the fixed side lower surface portion 65.
- the engaging convex portion 66 has a configuration in which a part of the annular fixed side lower surface portion 65 is protruded. Further, the height of the engaging convex portion 66 is set to be equal to the height of the fixed side reference surface 63, and therefore the fixed side reference surface 63 and the engaging convex portion 66 are flush with each other.
- the engaging convex portion 66 configured in this way is disposed on the opposite side of the fixed high surface portion 64 with respect to the center position of the oval hole 69.
- the shaft 2 is inserted into the oval hole 69.
- the engaging convex portion 66 is formed at a position opposite to the fixed high surface portion 64 with the axis X of the shaft 2 as the center. ing. Therefore, the fixed-side high surface portion 64 and the engaging convex portion 66 are arranged 180 degrees apart.

- the inclination angle of the inclined surface 68 is set to an angle corresponding to the inclination angle of the inclined surface 48 formed on the rotary cam 4.
- the fixed cam 6 is disposed in the case 12 so as to rotate together with the head 10. That is, the fixed cam 6 is disposed in the case 12 with the shaft 2 inserted through the oval hole 69. At this time, the shape of the oval hole 69 is an oval shape, and the cross-sectional shape of the shaft 2 is also an oval shape corresponding thereto. For this reason, the fixed cam 6 is configured to be non-rotatable with respect to 2. However, the fixed cam 6 is configured to be movable in the case 12 with respect to the axial direction of the shaft 2 (the directions of the arrows X1 and X2 in the drawing).
- the rotary cam 4 and the fixed cam 6 configured as described above are brought into contact (pressure contact) with the inner surfaces 42 and 63 of the rotary cam 4 and the fixed cam 6 by the spring 8 as described above. Further, the spring 8 is inserted into the shaft 2 so as to be arranged coaxially with the shaft 2. Due to the elastic force of the spring 8, friction (torque) is generated between the inner side surfaces 42 and 62.
- FIG. 8A and 9 show a state where the rotation side low surface portion 44 of the rotating cam 4 and the fixed side high surface portion 64 of the fixed cam 6 are engaged (hereinafter referred to as a cam meshing state).
- FIG. 9 is a perspective view showing the rotating cam 4 and the fixed cam 6 in a cam-engaged state.
- the position where the cam is engaged is set to a position where the lid 102 is closed with respect to the main body 101 in FIG. 9 (a position indicated by a lid 102a in the figure, hereinafter referred to as a closed position).
- a so-called suction action an action of increasing torque
- the lid part 102a can be regulated at the closed position, and rattling can be prevented from occurring in the lid part 102a.
- the rotation-side low surface portion 44 and the fixed-side high surface portion 64 are formed in only one place on the rotation cam 4 and the fixed cam 6, so the fixed-side high surface portion 64 is the rotation-side low surface portion 44.
- the above suction action is generated only once when rotating 360 °. Therefore, the suction action described above occurs only when the lid 102 is closed with respect to the main body 101 (when the lid is closed), and the lid 102 can be locked in the closed state.
- FIG. 8B shows a state where the fixed side high surface portion 64 is rotated 180 ° with respect to the cam meshing position by rotating 6 with respect to the rotating cam 4 (the state shown in FIG. 8C. Hereinafter, 180 ° is opened). It shows a state rotated to a position between (state). Specifically, a state in which the fixed cam 6 is rotated by 45 ° with respect to the rotating cam 4 from the cam meshing state (hereinafter referred to as a state during rotation) is shown.
- the fixed-side high surface portion 64 is separated from the rotation-side low surface portion 44 and is in sliding contact with the rotation-side reference surface 43. Further, the fixed side lower surface portion 65 is in sliding contact with the engagement recess 46. Further, the outer peripheral portion 64 a of the fixed side high surface portion 64 is in sliding contact with the inner wall 45 a of the rotation side high surface portion 45.
- FIG. 8C shows a state in which the fixed high surface portion 64 is rotated to the 180 ° open state by the rotation of the fixed cam 6 with respect to the rotating cam 4. Even in the 180 ° open state, the fixed-side high surface portion 64 is separated from the rotation-side low surface portion 44 and is in sliding contact with the rotation-side reference surface 43.
- the position of the lid portion 102b at the intermediate position between the closed state and the 180 ° rotated state corresponds to the state in which the hinge device 1 is being rotated.
- the position of the lid portion 102 c that is substantially horizontal with respect to the main body portion 101 corresponds to the 180 ° open state of the hinge device 1.
- the fixed cam surface 6 and the fixed cam 6 are in sliding contact with the rotating reference surface 43 between the rotating cam 4 and the fixed cam 6 even in the middle of rotation and 180 ° open state.
- the first slidable contact position and the second slidable contact position where the fixed-side lower surface portion 65 is in slidable contact with the engaging recess 46 are supported. Therefore, even in the mid-rotation state, there is no backlash between the rotating cam 4 and the fixed cam 6, and a stable rotating operation can be realized.
- the outer peripheral portion 64a of the fixed side high surface portion 64 is in sliding contact with the inner wall 45a of the rotation side high surface portion 45 (referred to as a third sliding contact position) in the middle of rotation. For this reason, the relative rotation of the rotating cam 4 and the fixed cam 6 is supported at the third sliding contact position in addition to the first and second sliding contact positions. Therefore, in the middle of the rotation, it is possible to reliably suppress the occurrence of rattling, and to further stabilize the relative rotational operation of the rotating cam 4 and the fixed cam 6.
- the fixed side high surface part 64 is detached from the rotation side low surface part 44, that is, in the middle of rotation and in the 180 ° open state, the fixed side high surface part 64 is brought into contact with the rotation side reference surface 43 by the elastic force of the spring 8.
- the engagement convex portion 66 is pressed against the rotary side high surface portion 45 while being pressed. Therefore, a frictional force generated between the fixed-side high surface portion 64 and the rotation-side reference surface 43 and a frictional force are generated between the engagement convex portion 66 and the rotation-side high surface portion 45.
- the lid body portion 102 can be free-stopped (locked at an arbitrary rotation angle) with respect to the main body portion 101. Visibility can be improved when a liquid crystal display device or the like is provided.
- a stable operation without backlash can be ensured even with a hinge device that locks once (generates suction) while rotating 360 °.
