TREAD CLEANING DEVICE
PROBLEM TO BE SOLVED: To reduce cost of a tread cleaning device.SOLUTION: A tread cleaning device 100 comprises: a connection mechanism 80 for connecting a polishing piece reception 40 and a polishing piece 50 detachably; a lock pin 70 for holding the connection mechanism 80 in a connection state; and a lock mechanism 90 for regulating movement of the lock pin 70. The lock mechanism 90 includes: a support part 43 for regulating falling of a rod part 71 from an engagement hole 49; and an engagement member 11 for regulating rotation of a grip part 72. When the grip part 72 is rotated in one side around the rod part 71, the grip part 72 contacts the engagement member 11 for shrinking a spring 12, thereby the engagement member 11 retreats, and the grip part 72 can rotate beyond the engagement member 11, on the other hand, when the grip part 72 rotates beyond the engagement member 11, rotation of the grip part 72 in the other side around the rod part 71 is regulated by the engagement member 11.SELECTED DRAWING: Figure 1
【課題】踏面清掃装置のコストを低減する。【解決手段】踏面清掃装置１００は、研摩子受け４０と研摩子５０とを着脱自在に連結する連結機構８０と、連結機構８０を連結状態に保持するロックピン７０と、ロックピン７０の移動を規制するロック機構９０と、を備え、ロック機構９０は、ロッド部７１の係止孔４９からの抜けを規制する支持部４３と、把持部７２の回動を規制する係止部材１１と、を有し、把持部７２がロッド部７１を中心として一方側に回動する際には、把持部７２が係止部材１１に当接してばね１２を収縮させることによって係止部材１１が後退し、把持部７２が係止部材１１を超えて回動することが許容される一方、把持部７２が係止部材１１を超えて回動した後は、ロッド部７１を中心とする他方側への把持部７２の回動は、係止部材１１によって規制される。【選択図】図１
