To provide a traction gear capable of reducing a load applied on a motor shaft of a motor.SOLUTION: A traction gear 21 comprises: a turning arm 30 connected so as to be turnable about a turning shaft in a vertical direction orthogonal to the advancing direction of an unmanned carrier body 20; and a lifting arm 31 moved in the vertical direction with respect to the turning arm 30. The lifting arm 31 has a hook 32 connected to a traction object, and a cam follower 34. An end surface cam 33 is installed in the turning arm 30 so as to be rotatable about a cam rotary shaft 67 in the vertical direction. The end surface cam 33 has a cam surface 68 annularly formed about the cam rotary shaft 67 to support the cam follower 34. A motor 35 for rotating the end surface cam 33 is installed in the turning arm 30. By lifting the lifting arm 31 via the cam follower 34 through the rotation of the end surface cam 33, the position of the hook 32 is changed to a position for connection to the traction object and a position for releasing the traction object.SELECTED DRAWING: Figure 4

    【課題】モータのモータ軸に加わる負荷を軽減できる牽引装置を提供する。【解決手段】牽引装置21は、無人搬送車本体20の進行方向に対して交差する上下方向の旋回軸を中心に旋回可能に連結される旋回アーム30と、旋回アーム30に対して上下方向に移動する昇降アーム31とを備える。昇降アーム31は、牽引物と連結するフック32と、カムフォロア34とを有する。旋回アーム30に、上下方向のカム回動軸67を中心に回動可能に端面カム33を設置する。端面カム33は、カム回動軸67を中心とする環状に形成されてカムフォロア34を支持するカム面68を有する。旋回アーム30に、端面カム33を回動させるモータ35を設置する。端面カム33の回動により、カムフォロア34を介して昇降アーム31を昇降させることで、フック32の位置が牽引物と連結する位置と牽引物を解放する位置とに変化する。【選択図】図4
