れる。The structure of this conventional window will be described with reference to FIGS. 8 and 9 (in this example, the structure of the front lens window (3) is shown). The window hole (5) has a stepped portion (5a) on the inner periphery thereof, and a ring-shaped rubber packing (6) is provided between the stepped portion (5a) and the stepped portion (5a). A glass transparent plate (7) is fitted into the window hole (5) while being sandwiched, and the transparent plate (7) is further fixed to the window hole (5) by a ring-shaped holding frame (8).
It is designed to be pressed against the step (5a) and fixed. Conventionally, the holding frame (8) has a structure to be assembled with screws (9), that is, a tongue-shaped fixing piece (10) protrudes from the outer peripheral surface of the holding frame (8). The screw (9) is screwed into the screw hole (12) of the waterproof case main body (1) through the mounting hole (11) formed in the piece (10), so that the presser frame (8) is attached to the waterproof case main body (1). ) Is held in a fixed state, that is, the transparent plate (7) is fixed to the window (5) in an airtight state.

る。The conventional waterproof case window configured as described above has a structure in which the holding frame (8) is assembled and fixed to the waterproof case main body (1) by the screws (9). That is, the assembly workability is poor, and the cost of manufacturing the waterproof case is high. In addition, since the screw fixing portion requires a relatively large mounting area, the space of the window portion occupying the waterproof case main body is increased, and as a result, the waterproof case is prevented from being downsized.
本考案は斯る点に鑑みてなされたもので、組立が簡単
でしかもスペースを要せず確実に組立てられる窓部の構
造を提供することを目的とする。The present invention has been made in view of the above point, and an object of the present invention is to provide a structure of a window portion which is easy to assemble and can be securely assembled without requiring a space.
