FIG. 3 is a perspective view of a main body 11 of an in-vehicle device such as a car stereo or a car radio. This main body 11 is made of metal, and has a nose portion 12 made of resin fixed to its front end. Although not shown, operation buttons, switches, a display section, and the like are provided on the front surface of the nose section 12. Furthermore, a recess 11a is formed by bending on both side plates of the main body 11, and a hole 11b is bored in front of the recess 11a. In FIG. 3, a recess 11 in one side plate of the main body 11 is shown.
A and hole 11b are shown, but the same one is provided on the other side plate. As shown in FIGS. 5 and 6, locking members 13 are fixedly provided in the recesses 11a of both side plates. This locking member 13 is made of a leaf spring material, and its base is fixed to the recess 11a with a screw 14. Further, the locking member 13 has a central portion 13b bent into a dogleg shape, and a hook 13a bent at a right angle is formed at the tip. As shown in FIG. 7, a notch 13c is formed in this hook 13a. This hook 13a protrudes from the hole 11b due to its own elasticity. On the other hand, as shown in FIGS. 3, 5, and 6, the nose portion 1
Operation holes 12a are bored at both the left and right ends of 2. This operation hole 12a is formed approximately on the same line as a notch 13c formed in the hook 13a of the locking member 13.

Furthermore, the dash board 3 to which the main body 11 and the like are attached has a square mounting hole 3a, which is the same as that shown in FIG. (See Figure 4). This inner case 15 has almost the same structure as that shown by reference numeral 4 in FIG. That is, the inner case 15 is formed into a rectangular tube shape, and a flange 15a around the opening thereof is secured to the front surface of the dash board 3, and an elastic piece similar to the reference numeral 4b in FIG. The inner case 15 is fixed by being locked or the like. Furthermore, recesses 15b are formed in the left and right side plates of the inner case 15, and a stepped portion A is formed in the main body 11.

When the main body 11 is inserted into the inner case 15, as shown in FIGS. 4 and 5, the main body 1
Due to the elastic force of the locking member 13 in the hook 13
a protrudes outward from the hole 11b of the main body 11, and this hook 13a fits into the recess 15b of the inner case 15.
The main body 11 is fixed within the inner case 15 by fitting into the stepped portion A. Further, the nose portion 12 is installed in substantially close contact with the front surface of the dart board 3.

Next, a procedure for taking out the main body 11 and nose portion 12 from inside the dash board 3 will be explained.

Two tools 20 shown in FIGS. 6 and 7 are used for this work. This tool 20 has a round bar shape, and has a taper 20a formed at its tip. Further, a protrusion 21 is fixedly provided at an intermediate position. For the removal work, first, use the two tools 20 to insert the operation holes 1 formed in both the left and right parts of the nose part 12.
Insert into 2a. At this time, insert it so that the protrusion 21 fixed to the tool 20 is facing sideways,
The protrusion 21 is made to pass through the notch 13c of the hook 13a. When the tool 20 is inserted, the taper 20a at the tip of the tool 20 aligns with the center bent portion 1 of the locking member 13.
3b, the locking member 13 is forcibly elastically deformed inward of the main body 11 (see FIG. 6). Then, the hook 13a is removed from the step A formed by the recess 15b of the inner case 15. At this time, as shown in FIG. 7, the tool 20 is rotated to move the protrusion 21 to a position where it is removed from the notch 13c,
Hook the protrusion 21 inside the hook 13a. Then, as shown in FIG. 6, the hook 13a is removed from the stepped portion A, and the protrusion 21 of the tool 20
3a, pull the tool 20 forward. As a result, the main body 11 and the nose portion 12 come out of the inner case 15.

Further, the work of attaching the main body 11 can be done by performing the above series of operations in reverse.

[Effects of this invention]

As described above, according to the present invention, the following effects can be achieved.

(1) A leaf spring with a hook is provided in the main body, and a fitting part is formed in the inner case, and the main body is fixed to the inner case by fitting the hook into the fitting part. This eliminates the need to provide a separate gasket 6 for covering the lever 5 of the nose portion 2 shown in FIG. 1 as in the conventional case, and the number of parts can be reduced.

(2) Since the leaf spring has a part extending diagonally toward the inside of the main body, the plate can be removed by simply inserting a tool through the operation hole and pressing the diagonal part of the leaf spring with the pressing part of the tool. The fitting between the spring hook and the fitting portion of the inner case can be released, making it easier to remove the vehicle-mounted equipment.

(3) Since a protrusion is formed on the tool, after the tool is inserted through the operating hole in the nose section and the hook and fitting part are released, the protrusion is locked inside the hook. The main body and nose part can be pulled out along with the tool by simply pulling. This further simplifies the removal work of the on-vehicle equipment.
