む。FIG. 1 shows how a main body case 1 and a rotating body case 2 of a portable telephone and hinge functional parts integrated with the rotating parts 1a and 2a are mounted. FIG. 2 is an enlarged view of the integrated hinge functional part according to claim 1, and FIG. 3 is an exploded view of the individual parts. The fixed cam 3 performs a click function when the trapezoidal portions 3a and 5a are fitted with the moving cam 5 pressed by the coil spring 4, and generates friction when the trapezoid portions 3a and 5a come off during rotation. Slot 5b of moving cam 5
The movable cam 5 and the shaft 6 rotate together and move only in the axial direction because the oval-shaped portion 6a of the shaft 6 is inserted through. The shaft 6 rotates together with the main body case 1 because the elastic projection 6b is fitted in the concave portion 1aa of the rotating portion 1a of the main body case 1. This elastic projection 6
Since b is formed on the elastic plate portion 6ba which is bent by elasticity,
The shaft 6 can be mounted on the main body case 1 simply by pushing it in the axial direction. The groove 3b of the fixed cam 3 also has a rotating body case 2.
Is fitted into the protrusion 2aa of the rotating part 2a of
It rotates together with the rotator case 2. The small projection 6c at the tip of the shaft 6 is for assembling only the hinge functional component so as not to come off in the axial direction, and has a play with the fixed cam 3 after being mounted on the case. In FIG. 4, the elastic projection 6b is directed toward the inner diameter side, and the hole 1ab of the rotating portion 1a into which the elastic projection 6b fits needs to have a length in the axial direction like the above-described recess 1aa because of the hole shape. Since it is not performed, the rotating part can be made smaller accordingly. The assembly can be mounted on the main body case 1 simply by pushing in the axial direction, as described above. With this structure, it is possible to reduce the size and the number of components as compared with the conventional case where a cylindrical component is provided as a rotation stopper for a component performing the moving cam function.

る事が可能である。FIG. 5 shows an example in which the elastic projections 6b are used instead of the elastic projections 6b.
A rigid projection 6e is provided on a cylindrical portion 6d acting as a rigid body. The coil spring, the moving cam and the fixed cam are not shown in the figure, but if the rigid projection 6e is turned slightly after pushing the shaft 6, the assembly is completed by the reaction force of the coil spring 4. . In this structure, although it is not much different from that described above that the size can be reduced, the structure is difficult to be disengaged even when the force of the coil spring 4 is increased, so that a large hinge torque can be exerted.

ことになる。FIG. 6 shows a case where the rotating part 1a of the main body case 1 is not penetrated. Assembling is performed by providing a bank 1ad at the bottom of the hole of the rotating portion 1a as a rotation stop, and fitting the bank 1ad with a groove at a position opposite to the shaft 7. As an assembling procedure in this case, all the hinge functional parts are fitted into the rotating portion 1a of the main body case 1, and the back surface of the fixed cam 3 is further pressed down to the same surface as the opening surface of the rotating portion 1a by, for example, a holding member 8. After that, if the rotating portion 2a of the rotating body case 2 is shifted sideways together with the holding member 8, the assembly is completed. In this configuration, since there is no hinge functional component that can be seen from the outside, it is not necessary to pay attention to the external appearance, and the possibility of dust entering is reduced and the probability of failure is reduced.

であり、その場合はヒンジ機能部長さを短くし得る。FIG. 7 shows a hinge structure in a case where there is no cylinder portion on the case side and a hole for a hinge is simply prepared, and in a case where an opened / closed object is subsequently rotated. The structure of the hinge itself is the same as that described above, and the rotary cylinder 9 is provided with a simple circular shaft portion, the support shaft 10 is provided with an oval-shaped portion 10a, and is shrunk in the axial direction to fit into the hole of the main body 11. The hinge function as opening and closing is completed. The hinge as a rotation
If the rotating unit 10 is provided with an orthogonal tubular portion that is integrated perpendicular to the opening / closing axis, and the same hinge functional component as described above is assembled, the assembly is completed. It is possible to provide a hinge function by using, for example, a wave washer 12 instead of the coil spring. In this case, the length of the hinge function portion can be shortened.

だ後少し回すだけなので、簡単に行える利点が有る。It is particularly desirable for portable equipment to be small and light, and as described above, the rotating portion of the main body case or the rotating body case is directly prevented from rotating and retaining the axis of the hinge function. If this is the case, there is an advantage that the size can be reduced and the number of parts can be reduced, so that the weight can be reduced. Also, since the number of parts is small, the assembling is easy, and the assembling to the main body can be performed simply by pushing in the axial direction or turning a little after pushing in, so that there is an advantage that it can be easily performed.
