Description of the Related Art In general, a bottom of an outer peripheral portion of a housing of an electronic device or the like is provided with rubber feet or the like so that the bottom does not contact an installation surface and the housing does not easily move. A leg member is provided. In the conventional rubber leg mounting structure, even if a load parallel to the surface of the installation portion acts on the member to be mounted on the housing, the rubber leg should not easily fall off the member to be mounted. For example, as shown in FIG. 9, a concave portion 2a into which the rubber leg 8 is inserted and bonded is provided on the mounted member 2. The attached member 2 is, for example, a bottom portion of a housing provided at a portion facing the installation section 10 in which a housing of an electronic device or the like is installed. One end surface of the rubber leg 8 is fixed to the bottom of the concave portion 2a with the double-sided adhesive tape 4. Therefore, the gap 6 is formed between the mounted member 2 and the installation portion 10 by supporting the mounted member 2 with the rubber legs 8.

Further, as another example of a rubber leg mounting structure, as shown in FIG. 10, through holes 12a and 18a through which screws Bi for fastening the rubber legs 18 are formed are provided. The rubber legs 18 are provided on a common axis. The attached member 12 is, for example, a bottom portion of a housing provided at a portion facing the installation portion 14 in which a housing of an electronic device or the like is installed. The large-diameter surface portion and the small-diameter surface portion of the rubber leg 18 having the shape of a truncated cone come into contact with the outer surface portion of the mounted member 12 and the installation portion 14, respectively. The rubber leg 18 has a through hole 18a communicating with a concave portion 18b formed therein, and a through hole 12a.
The screw Bi is inserted into the mounting member 12 via the washer wa and fastened by a nut Nu disposed on the inner space 12A side of the mounted member 12 to be fixed. Therefore, the mounted member 12 is supported by the rubber legs 18 so that
A gap 16 is formed between the member to be mounted 12 and the installation portion 14.
