To provide a method suppressing a slip of a rail travel mechanism or the like.SOLUTION: In a rail travel mechanism provided with a roller constituted to be able to travel along a rail, the roller comprises a shaft member as a rotation axis of the roller, a first roller member which is supported by the shaft member and rotatable around the rotation axis and a second roller member which is arranged to oppose the first roller member and supported in a rotatable fashion around the rotation axis by the shaft member and the rail travel mechanism is constituted to be able to change the distance between the first and second roller members in the rotation axis direction in response to a slip between the roller and the rail and press the rail with the roller.SELECTED DRAWING: Figure 1

    【課題】レール走行機構の滑りを低減する他の技術を提供する。【解決手段】レールに沿って走行可能に構成されたローラを備えるレール走行機構であって、ローラは、ローラの回転軸となる軸部材と、軸部材で軸支され、回転軸周りに回転可能な第1ローラ部材と、第1ローラ部材と対向して配置され、回転軸周りに回転可能に軸部材で軸支された第2ローラ部材と、を備え、レール走行機構は、ローラとレールとの滑りに応じて、第1ローラ部材と第2ローラ部材との回転軸方向の距離を変更して、ローラによってレールを押圧可能に構成されている。【選択図】図1
