BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to FIG. The mounting structure 1 of the sliding component 30 (component; eg, mode switching slider, lever, etc.) to which the present invention is applied can be slidably mounted on the housing 10 of an electronic device such as a tape recorder. It is attached to (movably).

That is, specifically, the protruding guide portion 20 that allows the sliding component 30 to move in an externally inserted state is formed by subjecting a part of the housing 10 to deformation, and the protruding guide portion 20 is formed. The slip-prevention member 40 for externally inserting the slide component 30 and for preventing the slide component 30 from coming off from the protruding guide portion 20.
Is provided. The housing 10 has a plate-shaped portion 11 made of metal. Further, the protruding guide portion 20 has a substantially cylindrical shape, and its protruding length is equal to or larger than the thickness of the sliding component 30, and its outer diameter is larger than that of the guided hole 31 provided in the sliding component 30. It is formed by subjecting the plate-shaped portion 11 to burring so as to be slightly smaller. The burring process is a well-known process in which a hole of a plate-shaped part is stretched and formed. Also, the outer peripheral portion 21 of the protruding guide portion 20 is formed by performing burring, while the screw 4 exemplified as the retaining member 40 is provided.
The inner peripheral portion 22 to which 2 (described later) is fixed is also formed.

On the other hand, the retaining member 40 has a protruding guide portion 20.
For example, a screw 42 (fastening member 4 is fastened to the inner peripheral portion 22 of the
1). The screw 42 has a male screw portion 43 having a thread cut off and a head portion 44 having a larger diameter than the male screw portion and preventing the sliding component 30 from coming off. That is, the diameter of the head portion 44 is set larger than the guided hole 31 provided in the sliding component 30.

Now, a method of mounting the sliding component 30 will be described. First, the guided hole 31 provided in the sliding component 30 is externally inserted into the protruding guide portion 20, and the sliding component 30 is attached to the housing 10. As a result, the sliding component 30 is slidably guided by the outer peripheral portion 21 of the protruding guide portion 20. Next, a screw 42 for preventing the sliding component 30 from coming off is attached to the protruding guide portion 20 by screwing it into the inner peripheral portion 22 from the opening of the protruding guide portion 20 on the protruding direction side. As a result, the sliding component 30 is slidable (movable) with respect to the protruding guide portion 20 in a state where the sliding component 30 is retained by the head portion 44 of the screw 42 with respect to the protruding guide portion 20.

It should be noted that the male screw portion 43 and the inner peripheral portion 22 are the same as the inner peripheral portion 2 when the male screw portion 43 is screwed into the inner peripheral portion 22.
The relative hardness difference is set so that 2 is threaded. Therefore, when the male screw portion 43 is screwed into the inner peripheral portion 22, a female screw portion that is screwed with the male screw portion 43 is formed on the side wall thereof. Further, the male screw portion 43 is set to have a size such that the tip portion thereof does not project inside the housing 10 when the screw 42 is screwed into the inner peripheral portion 22, for example.

As described above, according to the mounting structure 1 of the sliding component 30 of this embodiment, the protruding guide portion 20 that makes the sliding component 30 movable in the extrapolated state is provided in the housing 10. Since it is formed by subjecting the constituent plate-like portion 11 to burring, it is not necessary to provide a separate member when the sliding component 30 is slidably attached to the housing 10,
The number of parts can be reduced and the cost can be reduced. Further, in a state where the sliding component 30 is externally inserted into the protruding guide portion 20 and further the screw 42 for preventing the sliding component 30 from coming off is provided in the protruding guide portion 20, the sliding component 30 is attached to the protruding guide portion 20. Since it is movable, it is only necessary to fix the screw 42 provided on the protruding guide portion 20, and it is possible to reduce the number of assembling steps and improve the productivity. Therefore, the cost can be reduced and the productivity can be improved.

The plate-shaped portion 1 forming a part of the housing 10
By subjecting 1 to burring processing, the protruding guide portion 2
0 can be easily formed.

Further, the retaining member 40 has a protruding guide portion 20.
Since it is the screw 42 fixed to the inner peripheral portion 22 of the
It is possible to easily prevent the sliding component 30 from coming off simply by fixing 2 to the inner peripheral portion 22 of the protruding guide portion 20.

Further, since the screw 42 is attached from the opening on the protruding direction side of the protruding guide portion 20, the cut portion of the protruding guide portion 20 formed by the burring process is covered with the screw 42. Sliding parts 30
It is possible to improve the safety when handling items such as.

The present invention is not limited to this embodiment, and any modification can be made without departing from the spirit of the present invention. For example, in this embodiment, the tape recorder is illustrated as the electronic device, but the electronic device is not limited to this. For example, another audio device such as a disk reproducing device may be illustrated. In addition, in this embodiment, as a component movably attached to the housing 10,
Although the sliding component 30 such as a slider and a lever for mode switching is illustrated, the invention is not limited to this, and a rotating component such as a gear of a rotary drive system may be illustrated. Further, in this embodiment, the screw 42 is illustrated as the fastening member 41, but the fastening member 41 is not limited to this, and may be any one that can prevent the sliding component 30 from coming off. good. For example, a nail or the like may be used as the fastening member 41.

[0020]

According to the present invention, since the protruding guide portion for moving the component in the extrapolated state is formed by processing a part of the housing, when the component is movably attached to the main body. Since it is not necessary to provide a separate member in the above, the number of parts can be reduced and the cost can be reduced. Further, since the component is movable with respect to the protrusion guide portion in a state in which the component is externally inserted into the protrusion guide portion and the stopper member for preventing the component from coming off is provided on the protrusion guide portion, the component is movable with respect to the protrusion guide portion. It suffices to perform only the work of attaching the retaining member, which can reduce the number of assembling steps and improve productivity. Therefore,
The cost can be reduced and the productivity can be improved.
