To provide a method by which attaching/detaching a refraction type crossing gate bar to/from a railroad crossing gate is made to be easier.SOLUTION: In a weightless type railroad crossing gate 60, a contacting tool attaching and detaching part 66 with which a contacting tool 30 is attachable to and detachable from a housing body 41 that includes a motor axially rotating a main shaft 42 and an auxiliary spring 52 is provided. A refraction type crossing gate bar 20 can be attached, in a sidewise laid state, to a crossing gate bar holding mechanism 44 so as to facilitate work by attaching a transient replacement bar (21a) to the crossing gate bar holding mechanism 44 energized by the auxiliary spring 52 toward a crossing gate bar elevation side and operating the transient replacement bar to force the crossing gate bar holding mechanism 44 to move toward a crossing gate bar lowering side, and then, attaching the contacting tool 30 to the contacting tool attaching and detaching part 66 so as to regulate rotation of the crossing gate bar holding mechanism 44 toward the elevation side, and in this state, detaching the transient replacement bar (21a) and attaching the refraction type crossing gate bar 20.SELECTED DRAWING: Figure 1

    【課題】踏切しゃ断機に屈折式しゃ断桿を着脱する作業が楽に行えるように改良する。【解決手段】ウェイトレス式の踏切しゃ断機60について、その主軸42の軸回転を担うモータ及び補助ばね52を内蔵した筐体41に当接用具30を着脱しうる当接用具着脱部66を設けておく。補助ばね52によってしゃ断桿上昇側へ付勢されているしゃ断桿保持機構44に一時代用棒(21a)を仮装着して操作することでしゃ断桿保持機構44をしゃ断桿下降側へ強制してから、当接用具着脱部66に当接用具30を装着することでしゃ断桿保持機構44の上昇側への回転を規制し、その状態で一時代用棒(21a)を取り外して屈折式しゃ断桿20を取り付けることで、屈折式しゃ断桿20を横向きにした状態でしゃ断桿保持機構44に取り付けることができるので、作業が楽になる。【選択図】 図1
