PROBLEM TO BE SOLVED: To make it possible to simplify a structure and reduce the number of components thereby achieving down-sizing.SOLUTION: An opening/closing mechanism 1, which alternately performs an opening operation and a closing operation of a lid body 3 by a same operation by a same operation part 2, comprises: a crank mechanism 13 which converts rotational motion of a crank gear 11 into reciprocating-motion of a crank arm 12; and a half-rotation drive mechanism 14 which alternately performs a forward movement and a backward movement of the crank arm 12 by rotating the crank gear 11 of the crank mechanism 13 by each half-rotation. The lid body 3 is so connected to a tip of the crank arm 12 of the crank mechanism 13 as to be capable of opening/closing. Further, the operation part 2 is so located as to be capable of operating the semi-rotation drive mechanism 14.SELECTED DRAWING: Figure 1

    【課題】構造を簡略化し、部品点数を削減して、小型化が得られるようにする。【解決手段】同一の操作部2による同一の操作によって、蓋体3の開作動と閉作動とを交互に行わせるようにした開閉機構1に関する。クランク用ギヤ11の回転運動をクランクアーム12の往復運動に変換させるクランク機構13と、このクランク機構13のクランク用ギヤ11を半回転ずつ回動させてクランクアーム12に往移動と復移動とを交互に行わせる半回転駆動機構14と、を備える。そして、上記蓋体3が、上記クランク機構13のクランクアーム12の先端部に開閉可能に接続される。また、上記操作部2が、上記半回転駆動機構14を操作可能に設置される。【選択図】図1
