In this process, the elastic arm portion (44) of the partition plate (4) is elastically deformed so that the tongue piece (45) rides over the edge of the peripheral wall portion (13) of the rear case (12). By this, the partition board
The convex parts (46) (47) (48) (49) of (4) are the concave parts of the rear case (12).
It moves from (51) (52) (53) to the back surface side of the peripheral wall end portions (61) (62) (63) (64). As a result, in the partition plate (4), the rectangular main body (41) is received by the projecting pieces (54) (55) (56) of the rear case (12) and the convex portions (46) (47) (48) ( 49 will be pressed down by the peripheral wall end parts (61) (62) (63) (64) of the rear case (12). Also, the tongue piece (4) of the elastic arm (44) of the partition plate (4) is
5) is caught on the edge of the peripheral wall portion (13) of the rear case (12) to prevent it from coming off (see FIG. 4). As a result, a battery chamber (19) is formed at the back of the back case (12).
