- FIG. 1 the detailed structures of the engaged portion 13 and the engaging portion 23 will be further described with reference to FIGS. 4, 10 and 11.
- FIG. 1 the detailed structures of the engaged portion 13 and the engaging portion 23 will be further described with reference to FIGS. 4, 10 and 11.
- the housing 10 further has a guide portion 14.
- the guide portion 14 is arranged inside the housing 10 with respect to the mounting surface 10c.
- the guide portion 14 is arranged along the edge of the opening 10b.
- the guide portion 14 guides the engaging portion 23 of the panel 20 to the engaged portion 13 . Therefore, the operator can easily guide the engaging portion 23 to the engaged portion 13 by moving the engaging portion 23 of the panel 20 along the guide portion 14 . As a result, workability of attaching the panel 20 to the housing 10 can be improved.
- the guide part 14 is adjacent to the mounting surface 10c and extends along the Y-axis direction.
- the guide portion 14 has a guide surface 14a that intersects the mounting surface 10c.
- the guide surface 14a faces the panel 20 side.
- the pair of engaged portions 13 are arranged on the same plane including the guide surface 14a.
- the step surface 131a slopes downward toward the inside of the housing 10. As shown in FIG. Therefore, in a state in which the front end portion 233 of the engaging portion 23 is in contact with the stepped surface 131a of the engaged portion 13, a force acts on the panel 20 so as to move it in the positive direction of the X axis. Therefore, it is possible to reduce the force when the operator pushes the panel 20 toward the housing 10 (front side).
- the step surface portion 131 has an inclined surface 131c.
- the inclined surface 131c connects an end portion 131d of the stepped surface 131a on the outside of the housing 10 (in the negative direction of the X axis) and the mounting surface 10c.

- the mounting surface 10c is inclined downward toward the outside of the housing 10 (the negative direction of the X axis). Specifically, the inclination angle of the mounting surface 10c with respect to the horizontal plane is smaller than the inclination angle of the stepped surface 131a with respect to the horizontal plane. Further, in a state in which the tip portion 233 of the engaging portion 23 is arranged in the concave portion 132 of the engaged portion 13, the lower surface 231a of the base portion 231 contacts the mounting surface 10c. The lower surface 231a is inclined downward toward the outside of the housing 10 (the negative direction of the X-axis), like the mounting surface 10c. The lower surface 231a is substantially parallel to the mounting surface 10c.
- both the mounting surface 10c and the lower surface 231a are inclined with respect to the horizontal surface, but only one of the mounting surface 10c and the lower surface 231a may be inclined with respect to the horizontal surface. Moreover, the mounting surface 10c and the lower surface 231a do not have to be inclined with respect to the horizontal plane.
- the front end portion 233 of the engaging portion 23 is arranged in the concave portion 132 of the engaged portion 13. , a force acts on the panel 20 so as to move it in the negative direction of the X axis. Therefore, the state in which the tip portion 233 of the engaging portion 23 is in contact with the step surface portion 131 is maintained. That is, it is possible to prevent the panel 20 from rattling in the front-rear direction (Y-axis direction) with respect to the housing 10 .
- the intermediate portion 232 of the engaging portion 23 of the panel 20 contacts the stepped surface 131 a while the tip portion 233 is arranged in the recess 132 . Therefore, the contact state of the engaging portion 23 with the engaged portion 13 can be further stabilized.
- the tip portion 233 has a chamfered portion 233c on its upper portion.
