A cover part 500 is fixed to a frame member of a front door 2b by a catch 502 and a screw hole formed in a first boss part 503. The storage part 300 storing the stop switch board 400 is screw-fixed to a second boss part 504 formed on the back face of the cover part 500. A depressing operation part 220 includes a flange part 222 formed thereon for preventing pull-out thereof from an insertion hole 501 of the cover part 500.
