PROBLEM TO BE SOLVED: To prevent non-operation of a safety shoe, which may occur on a door closing end side, in advance and earlier than the detection of OFF failure on the door closing end side.SOLUTION: An operation inspection device of a safety shoe comprises a roller 13a provided at an upper end of a safety shoe 8; and a cam 11 disposed on a movement locus 30 of the roller 13a of a car frame 4 and supported on a rotation support part 12 swingably. The cam 11 moves the roller 13a along a top face 11b of the cam 11 while interlocking with opening operation of a door 1, forcibly moves the safety shoe 8 upward until the roller 13a passes the rotation support part 12, and operates a switch 11a during the moving process. After the roller 13a has passed the rotation support part 12, the cam 11 lowers the safety shoe 8 by swing operation of the cam 11 and maintains the lowered state of the safety shoe 8 until the door 1 is closed completely.SELECTED DRAWING: Figure 3 |
