ENGAGEMENT CHAIN DRIVE DEVICE AND MOVABLE BODY MOBILE DEVICE

PROBLEM TO BE SOLVED: To provide an engagement chain drive device capable of restricting vibration generated when the engagement chain is moved forward or rearward and a movable body mobile device capable of moving the movable body in a stable manner using the engagement chain drive device.SOLUTION: An engagement chain drive device 10 comprises an engagement chain 20 in which a pair of chain members 21A, 21B with pins 25A protruded toward side portions are engaged to each other to make an integral formation as they move in a forwarding direction and disengaged from each other and branched as they move in a retracting direction, and a rotating member 60 formed with a sliding groove extending gradually toward one side of a rotating shaft direction as it moves toward one side of its circumferential direction, with a forwarding or retracting direction under the engaged state of the engagement chain 20 as the rotating shaft direction. The pins 25A are slid along the sliding groove in response to the rotation of the rotating member 60 to enable the engagement chain 20 to be moved forward or rearward in the rotating shaft direction. 【課題】噛合チェーンを進退移動させる際に生じる振動を抑制することができる噛合チェーン駆動装置及び同装置を用いて可動体を安定的に移動させることができる可動体移動装置を提供する。【解決手段】噛合チェーン駆動装置１０は、側方へピン２５Ａを突出させた一対のチェーン部材２１Ａ，２１Ｂ同士が進行方向への移動に伴い相互に噛み合って一体化する一方で退行方向への移動に伴い相互に噛み外れて分岐する噛合チェーン２０と、噛合チェーン２０の噛合状態での進退移動方向を回転軸方向とし、その周方向の一方側へ向かうに連れて次第に回転軸方向の一方側へ向かうように延びる摺動溝が形成された回転部材６０とを備える。そして、回転部材６０の回転に応じてピン２５Ａを摺動溝に沿って摺動させることで噛合チェーン２０を回転軸方向に進退移動可能としている。【選択図】図１
