To provide a lock deviation detector with which a sign of lock deviation meaning a positional deviation of a lock piece from a lock rod notch in that the lock piece inserted can be early grasped.SOLUTION: Plural light receivers 61 to 64 and plural light emitters 51 to 54 both fixed to a switch 20 switching a railway turnout and plural movable slits 41 to 44 moving to follow a lock rod 22 of the switch 20 constitute plural light emitting and receiving units 41+51+61 to 44+54+64. The units are arranged in a direction of a movement of the lock rod 22 to function as parallelly arranged units 40 to 60 and the widths of the movable slits 41 to 44 are made to be different in the arrangement direction of the plural light emitting and receiving units. Lock deviation amounts are made to be multistage according to the plural units' conditions that the receiving light exists or not and this functions to determine an abnormality.SELECTED DRAWING: Figure 1
【課題】鎖錠かんの切欠とそこに挿抜されるロックピースとの位置ずれであるロック偏移の予兆を早期に把握しうるロック偏移検出器を実現する。【解決手段】鉄道における分岐器を転換する転てつ装置(20)に固定される複数の受光器61〜64及び発光器51〜54と、転てつ装置(20)の鎖錠かん(22)に追従して移動する複数の移動スリット41〜44とから、複数の送受光ユニット41+51+61〜44+54+64を構成するとともに、それらを鎖錠かん(22)の移動方向に並べて並設ユニット40〜60とし、更に移動スリット41〜44の幅を複数の送受光ユニットの間で異ならせる。複数の受光有無に応じてロック偏移量を多段に切り分け更に異常をも判別する。【選択図】 図1
