Ribs (87) comprise first ribs (87a) in contact with an outer side and second ribs (87b) in contact with a wall part, and a plurality of these first and second ribs is formed over the entire circumference of an edge part (82). A pressing part (88) is provided on a lid part (81) to face a relay (2), and when the locking part (67) locks onto a part to be locked (84), the pressing part (88) elastically deforms and presses the relay (2) onto the bottom part (61). |
