The opening / closing cover is configured to be rotatable around a predetermined rotation axis, and includes one side wall surface on one axial side of the rotation shaft and the other side wall surface on the other axial side. When rotating in the opening direction or the closing direction, the one side wall surface and the other side wall surface draw an arc locus centering on the rotation axis.

  When the opening / closing cover rotates in the closing direction and closes the opening, the locking portion and the locked portion are locked to each other and locked. One of the locking portion and the locked portion is provided on the casing, and the other is provided on the one side wall surface and the other side wall surface of the opening / closing cover. As described above, since the one side wall surface and the other side wall surface draw an arc locus centering on the rotation axis, the locking portion and the locked portion are relatively close to each other along the arc locus, Contact. At this time, the locking portion is locked by contacting the locked portion from one side in the orthogonal direction orthogonal to the axial direction of the rotation shaft and elastically pressing the locked portion to the other side. I do.

The claw portion 15B protrudes rearward from the tip of the base portion 15A, and is formed, for example, in a triangular side section (or a wedge shape in the side section).

  On the other hand, as shown in FIG. 13 and FIG. 14, the left and right ends of the inner wall portions of the left wall surface 5D and the right wall surface 5C of the opening / closing cover 5 (that is, the left and right ends of the top plate 5F) Horizontal rib-like locked portions 16 and 16 are formed on the left wall surface 5D and the right wall surface 5C. As shown in FIG. 13, the locked portion 16 is in the closed state in the closed cover 5 (in the direction perpendicular to the rotation axis k of the hinge portion 60: in FIGS. 6, 7, and 9). (In the direction of arrow B) of FIG. Further, the front end portion of the locked portion 16 has a shape curved slightly downward so that the locked state after the locking portion 15 is locked with the claw portion 15B can be reliably maintained. (See also FIG. 17 described later).

As shown in FIGS. 15, 16, and 17, a substantially L-shaped notch 16 </ b> A is formed inside each locked portion 16. A vertically long rib-shaped guide portion 70 (see FIGS. 17, 11, and 12) provided on the inner side in the left-right direction with respect to the position of each locking portion 15 can be engaged with the notch portion 16 </ b> A. ing. As a result, each locked portion arriving along an arc locus C (see FIGS. 14A and 17) centering on the rotation axis k of the hinge portion 60 due to the rotation of the opening / closing cover 5 in the closing direction. In contrast, the guide portion 70 comes into contact with the inner side in the left-right direction and guides the outer side in the left-right direction.

Then, it is assumed that the open / close cover 5 manufactured in this way is deformed so that the U-shape is opened, and the relative positional relationship between the left wall surface 5D and the right wall surface 5C in the left-right direction and the housing 2 is slightly shifted. However, it is possible to reliably maintain the firm lock state.

  In particular, in the present embodiment, since the top plate 5F, which is a separate member, is attached so as to cover the U-shaped inner edge of the opening / closing cover 5, unlike the case where the top plate 5F is configured as an integrated object, The opening and closing cover 5 is likely to be deformed so that the U-shape is opened. Therefore, the configuration of the present embodiment as described above in which the locking operation of the locking portion 15 is performed along the front-rear direction (along the direction orthogonal to the rotation axis k) is effective.

  Further, in the present embodiment, in particular, a guide portion 70 that contacts the locked portion 16 from the inner side in the left-right direction and guides it to the outer side in the left-right direction is provided. When approaching along the arc locus C, the locked portion 16 is guided along the left-right direction. Thereby, a smoother locking operation by the engaging portion 15 can be ensured.

  In the above embodiment, the locking portion 15 is provided on the housing 2 and the locked portion 16 is provided on the left wall surface 5D and the right wall surface 5C of the opening / closing cover 5, but this is not the case. In addition, a structure equivalent to the locked portion 16 is provided in the housing 2, and a structure equivalent to the locking portion 15 is provided in the left wall surface 5D and the right wall surface 5C of the opening / closing cover 5, and thereby the same longitudinal direction as described above. The locking may be performed. In this case, the same effect is obtained.
