Specifically, the movement of the antenna 22 in the F2 direction is restricted so as to be sandwiched between the engaging portion 550 and the end portion 720a of the second wall portion 720.

  The antenna 22 is housed / removed in / from the antenna housing portion 22a. When the antenna 22 is housed in the antenna housing portion 22 a, the engaging portion 550 contacts a part of the surface of the antenna 22. Further, when the antenna 22 is detached from the antenna housing portion 22a, the engaging portion 550 contacts substantially the same portion of the surface of the antenna 22 that the engaging portion 550 contacts when the antenna 22 is stored. . That is, the engaging portion 550 contacts a part of the surface of the antenna 22 every time the antenna 22 is stored / detached. Here, since the engaging portion 550 is a soft member having elasticity, the engaging portion 550 is deformed according to the movement of the antenna 22 and does not damage the surface of the antenna 22.

  According to the present embodiment, since the engaging portion 550 is formed of the silicon rubber sheet 500, the surface of the antenna 22 is hardly scratched even if the storing / removing operation of the antenna 22 with respect to the antenna storing portion 22a is repeated.

  Moreover, according to this embodiment, since the engaging part 550 was formed in a part of the sheet | seat 500 which comprises the operation key 21 arrange | positioned in the vicinity, a number of parts can be reduced. Furthermore, the engaging portion 550 can be formed simultaneously with the molding of the sheet 500. Thereby, parts cost and a manufacturing cost burden can be suppressed.

  Moreover, according to this embodiment, since the 2nd part 520 can be arrange | positioned so that the opening 600 may be filled, it can be set as the structure which can suppress permeation of water and dust.

  As mentioned above, although preferred embodiment of this form was described, this invention can be implemented with a various form, without being limited to embodiment mentioned above. For example, in the present embodiment, the engaging portion 550 is formed by a part of the sheet 500 constituting the operation key 21, but is not limited thereto, and is formed by a part of the sheet constituting another operation key. May be.

  Further, in the present embodiment, the sheet 500 including the engaging portion 550 is made of the same silicon rubber as a whole, but is not limited thereto, and the first portion 510 and the second portion 520 are made of different materials. May be. In this case, the sheet 500 can be molded by two-color molding. Further, all or a part of the sheet 500 may be formed of another elastic member instead of silicon rubber. Further, the sheet 500 may be formed so that only the engaging portion 500 becomes an elastic member.
