有している。In this structure, the pivot member 3 can be integrally formed of resin or the like, and is used as a member when the movable body 2 is attached to the fixed main body 1. That is, the pivot member 3
Is temporarily assembled along the edge 2a on the base end side of the movable body 2 and then fitted by a sliding operation in a state where the insertion portion 3d faces the corresponding shaft hole 1b of the fixed body 1. Specifically, as illustrated in FIGS. 2 and 3, the C-shaped opening 3 a is made to correspond to the base-side edge 2 a of the movable body 2, and the edge 2 a is formed into a cylindrical shape from the opening 3 a by a pushing operation. When pushed into the interior, the pivot member 3 is temporarily assembled by sandwiching the movable body 2 by the elastic force of the cylindrical half portions 3b and 3c. Thereafter, as shown in FIG. 1 (b), the pivot member 3 moves the edge portion 2 until the projection 5 hits the inner surface 1c defining the opening 1a of the fixed body 1.
When the sliding operation is performed along a, the insertion portion 3d is fitted into the corresponding shaft hole 1b, and as a result, the movable body 2 is attached to the fixed main body 1 so as to be rotatably supported. Therefore, the pivot member 3 of the present invention is formed of a simple single member, and can be easily assembled without requiring a hole processing or the like on the movable body 2 side. More importantly, it can be applied to the case where the movable body 2 is thinner, it is easy to increase the strength by securing the shaft diameter, and there is no problem even if the protrusion 5 is formed thinner. 7, the gap between the width X of the opening 1a and the width Y of the movable body 2 can be structurally reduced.

This is a configuration having a resilient plate portion 7 with an attached. In this structure, the pivot member 3 is temporarily assembled to the edge 2a of the movable body 2 as described above, and then the insertion portion 3d is inserted into the corresponding shaft hole 1b.
When sliding in the direction, the sliding operation is facilitated by a finger or the like using the tongue piece 7a. Secondly, when the inner surface of the elastic plate portion 7 is integrally bulged and formed and slides along the edge portion 2a of the movable body 2 to a fixed position of the shaft hole 1b, its edge corner portion (edge portion 2a (Meaning the end face 2b that intersects with the end face 2b) to restrict the sliding in the opposite direction. In this structure, in a use state where the insertion portion 3d and the shaft hole 1b are fitted to each other or in a regular assembled state, an inadvertent sliding of the pivot member 3 is caused by the engagement between the step portion 8 and the edge corner portion (end surface 2b). This prevents movement and prevents the insertion portion 3d from falling out of the shaft hole 1b.

る。Thereafter, the movable body 2 is placed in the opening 1a of the housing 1 as shown in FIG. In this embodiment, since the pivot members 3 on both sides do not protrude to the side of the movable body 2 at this stage, the movable body 2 is easily arranged even if the movable body 2 has a size substantially equal to the opening 1a. . Next, after the pivot members 3 on both sides are positioned so as to coincide with the corresponding shaft holes 1b, the pivot members 3 are pushed by a finger or the like in the arrow direction in FIG. Then, the pivot member 3
Is moved in a direction protruding from the side of the movable body 2 like the pivot member 3 on the right side in FIG. 2, and the insertion part 3 is made as shown in FIG.
d is fitted into the shaft hole 1b and further slid until the projection 5 comes into contact with the corresponding inner surface 1c of the opening 1a of the housing 1. Further, in the sliding process so far, the end face of the edge portion 2a is in contact with the tapered surface 8a of the step portion 8. Immediately before the protrusion 5 comes into contact with the inner surface 1c, the end surface of the edge 2a (the upper end surface of the movable body 2 in FIG. 1) elastically rides over the tapered surface 8a, and the end surface 2b intersecting with the edge 2a is formed. The engagement with the end face 8b prevents the pivot member 3 from being slid in the direction (left side in FIG. 1) coming out of the shaft hole 1b by the engagement.

る。Therefore, when the insertion portion 3d and the shaft hole 1b are fitted, the pivot member 3 is restricted so as not to move in either the direction of the shaft hole 1b or the direction away from the shaft hole 1b. For this reason, the movable body 2 is rotatably assembled to the opening 1a of the housing 1 via the pivot members 3 on both sides, and there is no danger that the movable body 2 will be accidentally detached once assembled. When the movable body 2 is removed from this state, for example, the tongue piece 7a is picked up, and then the pivot member 3 is slid in a direction away from the shaft hole 1b.

なる。FIG. 6 shows a modification of the pivot member 3 described above. In the modification of FIGS. 6A and 6B, FIG.
FIG. 6C shows a cross section in the same mode as that of FIG. 6C, and the modified example of FIG. 6C shows the same mode as FIG. Therefore,
In the following description, new reference numerals are added to portions different from the above-described contents, and only the changed points will be described in detail. The modified example of FIG. 6A is an example in which the shape of the opening side end surface 9a of the cylindrical half portions 3b and 3c is changed. That is, the end faces 9a are formed in a tapered shape in which the inside is narrower than the outside, so that the edge 2a of the movable body 2 pushed into the opening 3a can be more strongly clamped by the wedge action. In contrast, FIG.
In the modified example (b), the opening side end surfaces 9b of the cylindrical half portions 3b and 3c are formed in an uneven shape or a saw shape, so that a frictional force is exerted on the edge 2a of the movable body 2 pushed into the opening 3a. It can be pinched. The modification of FIG. 6C is an example in which a guide concave portion 2c is provided on the edge 2a of the movable body 2. In this case, since the pivot member 3 clamps the edge 2a in a state where the opening side edges of the cylindrical half portions 3b and 3c are fitted into the guide recesses 2c, the pivot member 3 is temporarily assembled to the edge 2a. Even in the state, it will not come off accidentally.

る。As described above, the present invention only needs to have the technical elements specified in the claims, and the other elements can be variously modified as necessary. In addition to the above, the pivot member 3 may be used only in the case where the movable body 2 is provided with the pivot member 30 shown in FIG. 8B on one side, and only on the other side. It is also possible to do so. The shaft hole 1b is not limited to a blind hole, and may be a through hole.

られる。As described above, the pivot member of the present invention is formed of a simple single member, and can be easily assembled without requiring a mounting hole or the like on the movable body side. In this structure, since the movable body is inserted into the inside of a substantially C-shaped vertical section and is sandwiched, it can be applied even when the movable body is thin, and the assembling property to the movable body side is also improved. It is easy and has the basic effect that the required shaft diameter can be secured and the strength can always be secured. In addition to this, when fitting the insertion portion into the corresponding shaft hole, the pivot member slides along the edge of the movable body, and there is no problem even if the projection is formed thinly. As described above, the gap between the width dimension X of the opening and the width dimension Y of the movable body can be reduced, and the appearance in use can be maintained. And the like.
