DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the drawings showing preferred embodiments. As shown in FIGS. 1 to 4, the member attaching mechanism according to the first embodiment has the following configuration. The attachment mechanism of this member includes a pair of restricting portions 4 on the outer circumference of which a movable range D of the attached material 2 should be formed.
have. In this embodiment, the tube joint 10 is used as the member 1. Other than the tube joint 10 as described above, various members can be applied. For example, a nipple 14 for mounting a tube joint shown in a second embodiment to be described later, a speed control valve for controlling air pressure, a throttle valve, a regulator, a pressure valve, a vacuum generator, and other electric equipment.
Further, in this embodiment, the metal panel 2 is used as the material to be attached 2.
0 was used.

A metal panel 2 is provided on the outer periphery of the tube joint 10.
The pair of restricting portions 4 that should form the movable range D of 0 is formed as follows. In this embodiment, the E-shaped retaining ring 40 is adopted as the restriction portion 4, and the E-shaped retaining ring 40 is fitted into the circumferential groove 11 formed on the outer periphery of the tube joint 10. A pair of E-shaped retaining rings 40 are prepared, and one of them is fitted into the circumferential groove 11 of the tube joint 10 in advance. Since the E-shaped retaining ring 40 has a shape in which a part of the annular shape is omitted, it can be mounted to the tube joint 10 from the outside, and the minimum diameter portion thereof is slightly smaller than the diameter of the circumferential groove 11. It is set. Therefore, the E-shaped retaining ring 40 is attached to the circumferential groove 1
At the time of mounting on the No. 1, the minimum diameter portion spreads slightly outward at a position corresponding to the diameter of the circumferential groove 11 and then fitted. With such a setting method, the E-shaped retaining ring 40 is prevented from accidentally falling off after the tube joint 10 is attached to the metal panel 20. still,
Instead of fitting the E-shaped retaining ring 40 into the circumferential groove 11 of the tube joint 10 in advance, the convex portion with which the metal panel 20 should come into contact is provided as the restricting portion 4 so as to project on the outer periphery of the tube joint 10. You may stay.

The region between the pair of E-shaped retaining rings 40 is the movable range D of the metal panel 20 before the tube joint 10 is fixed to the metal panel 20. A biasing means 5 is arranged in the movable range D. In this embodiment, a corrugated washer 50 is used as the biasing means 5. The corrugated washer 50 has a shape in which the washer is provided with an uneven shape, and the width when it is extended (that is, the width at the normal time) is slightly smaller than the remaining width obtained by subtracting the thickness d of the metal panel 20 from the width of the movable range D. It is set large. A disc spring or the like may be used instead of the corrugated washer 50.

In this embodiment, a pair of E-shaped retaining rings 40 are used as the regulating portion 4, but a C-shaped retaining ring (not shown) may be adopted as the regulating portion 4. In this case, the C-shaped snap ring may be mounted from the outside in the longitudinal direction of the tube joint 10 with the split ring end being pushed open. Next, the usage state of the member attachment mechanism of this embodiment will be described.

The tube joint 10 is attached to the metal panel 20 as follows. First, the metal panel 20
The tube joint 10 is inserted into the mounting port formed in the above. The diameter of the attachment port is slightly larger than the outer diameter of the tube joint 10 and is a diameter that allows engagement with the E-shaped retaining ring 40. The metal panel 20 comes into contact with one of the E-shaped retaining rings 40 fitted in advance in the circumferential groove 11 on the outer periphery of the tube joint 10. Next, the other E-shaped retaining ring 40 is attached to the tube joint 10 by pushing it in from the outside (above). The wavy washer 50 disposed in the movable range D of the metal panel 20 formed by the pair of E-shaped retaining rings 40 has a width when it is extended and subtracts the thickness d of the metal panel 20 from the width of the movable range D. The width is set to be slightly larger than the remaining width. Therefore, the metal panel 20 is fixed by being applied with a pressing force by the corrugated washers 50 that try to expand in the movable range D.
Therefore, there is an advantage that it can be attached by a simple operation without using a tool.

Further, since it is not necessary to screw the outer periphery of the member as in the conventional case, it is possible to manufacture at a lower cost. Further, when the nut as in the conventional case is used, the screwed state may be gradually loosened due to vibration during transportation or use, but in this embodiment, the corrugated washer 50 always generates the biasing force. Therefore, there is an advantage that the tube joint 10 does not come loose from the metal panel 20.

As shown in FIGS. 5 to 7, the member attaching mechanism according to the second embodiment has the following structure.
The difference from the first embodiment will be mainly described. In this embodiment, a nipple 14 for mounting a tube joint is used as the member 1. Both ends of the tube joint mounting nipple 14 allow the tube joint 10 to come into contact with and separate from the tube joint 10. The tube fitting mounting nipple 14 has an outer periphery provided with a pair of restricting portions 4 for forming the movable range D of the metal panel 20, but the configuration is slightly different from that of the first embodiment.

The restricting portion 4 of this embodiment is a metal panel 2
Tube fitting mounting nipple 14 for abutting 0
The projecting portion 41 projecting from the outer periphery of the tube and the E-shaped retaining ring 40 that can be externally attached to the nipple 14 for attaching the tube joint are adopted. The convex portion 41 and the E-shaped retaining ring 40
A region between the metal panel 20 and the tube fitting mounting nipple 14 is fixed to the metal panel 20 before being fixed to the metal panel 20.
The range of motion D becomes.

Next, the usage state of the member mounting mechanism of this embodiment will be described. Tube fitting mounting nipple 14
When attaching to the metal panel 20, the following is done.
First, the tube joint mounting nipple 14 is inserted into the mounting port formed in the metal panel 20. The diameter of the mounting port is set to be slightly larger than the outer diameter of the nipple 14 for mounting the tube joint and to be capable of engaging with the convex portion 41. The metal panel 20 abuts on the convex portion 41 on the outer circumference of the tube joint 10. Then, the E-shaped retaining ring 40 is pushed into the tube joint 10 from the outside (upper side) to be fitted into the circumferential groove 11 formed on the outer circumference of the nipple 14 for mounting the tube joint, and attached. Wave washer 50 disposed in the movable range D
Is the width of the movable range D from the width of the extended range of the metal panel 2
The width is set to be slightly larger than the remaining width after subtracting the thickness d of 0. Therefore, the metal panel 20 is fixed by being applied with a pressing force by the corrugated washers 50 that try to expand in the movable range D. Therefore, there is an advantage that it can be attached by a simple operation without using a tool.

[0016]

The present invention having the above-mentioned structure has the following effects. When the member 1 is inserted into the mounting opening formed in the mounted material 2 and the regulating portion 4 is mounted from the outside of the member 1, the mounted material 2 tends to extend in the movable range D. Since a pressing force is exerted and fixed by 5, it is possible to provide an attachment mechanism of a member that can be attached by a simple operation.
