To provide a constitution such that control over a wear state of a brake block can be automated.SOLUTION: A brake block wear detection unit comprises a fitting member, a switch and an RFID tag. The fitting member is fixed to a first member consisting of one of a base member and a movable member. The switch is provided to the fitting member, and changes an electric state according to a quantity of relative displacement with respect to a second member consisting of the other of the base member and the movable member. The RFID tag is provided to the fitting member, and electrically connected to the switch, and has storage information rewritten in response to a change in the electric state of the switch.SELECTED DRAWING: Figure 4
【課題】制輪子の摩耗状態の管理を自動化できる構成を提供する。【解決手段】制輪子摩耗検知ユニットは、取付部材、スイッチ及びRFIDタグを備える。前記取付部材は、ベース部材又は可動部材のいずれか一方からなる第1部材に固定される。前記スイッチは、前記取付部材に設けられ、前記ベース部材又は前記可動部材のいずれか他方からなる第2部材との相対変位量に応じて電気的状態を変化させる。前記RFIDタグは、前記取付部材に設けられ、前記スイッチに電気的に接続され、前記スイッチの前記電気的状態の変化に応じて記憶情報が書き換えられる。【選択図】図4
