CONVEYANCE MECHANISM, AND COMBINATION WEIGHING MACHINE

To provide a conveyance mechanism that makes it easy to consecutively weld a coupling member coupling a conveyance member of a trough to a plate member thereof.SOLUTION: A conveyance mechanism 1 has: a trough 10 that conveys articles; and a support member 30 that has the trough 10 detachably coupled, and has an oscillation part oscillating the trough 10. The trough 10 has: a conveyance member 12 that conveys articles; a plate member 11 that abuts with the support member 30; and a coupling member 20 that couples the conveyance member 12 to the plate member 11. The coupling member 20 has: a wall part 23 that has a circular cross section, and extends in a circular axis direction; a top end face that is located in a top end of the wall part 23, abuts with a conveyance member 12; and a lower end face that is located in a lower end of the wall part 23, and abuts with the support member 30. At least one of the top end face and the lower end face has an elliptical shape that has a longitudinal axis direction and a minor axis direction, and is a non-vertical end face in which an angle with respect to an outer circumferential face of the wall part 23 is non-vertical.SELECTED DRAWING: Figure 3 【課題】トラフの搬送部材とプレート部材と連結する連結部材を連続的に溶接し易い搬送機構を提供する。【解決手段】搬送機構１は、物品を搬送するトラフ１０と、トラフ１０が着脱自在に連結され、かつトラフ１０を振動させる振動部を有する支持部材３０と、を有する。トラフ１０は、物品を搬送する搬送部材１２と、支持部材３０に当接するプレート部材１１と、搬送部材１２とプレート部材１１を連結する連結部材２０と、を有する。連結部材２０は、円形の断面を有し、円形の軸方向に延びる壁部２３と、壁部２３の上端に位置し、搬送部材１２に当接する上端面と、壁部２３の下端に位置し、支持部材３０に当接する下端面と、を有する。前記上端面と前記下端面のうち少なくとも一方は、長軸方向と短軸方向を有する楕円形状であり、壁部２３の外周面に対する角度が非垂直である非垂直端面である。【選択図】図３
