To inhibit a shaft from being removed without using a removal prevention component in a structure in which a first member and a second member are rotatably connected by the shaft.SOLUTION: A rotary shaft structure includes: a shaft which rotatably connects a first member with a second member; a first bearing part which is provided at the first member and receives an axial end of the shaft inserted from the outside; a second bearing part which is provided at the second member and through which the shaft penetrates; and a restriction part which is provided at the first bearing part and contacts with an end surface opposite to an insertion direction of the shaft to restrict outward movement of the shaft.SELECTED DRAWING: Figure 9
【課題】第1部材と第2部材をシャフトで回転可能に連結する構成において、抜け止め用部品を用いなくてもシャフトが外れるのを抑制する。【解決手段】回転軸構造は、第1部材と第2部材を回転可能に連結するシャフトと、前記第1部材に設けられ、外方から挿入される前記シャフトの軸方向の端部を受ける第1軸受け部と、前記第2部材に設けられ、前記シャフトが貫通する第2軸受け部と、前記第1軸受け部に設けられ、前記シャフトの挿入方向と反対側の端面と接することで前記シャフトの外方への移動を制限する制限部と、を有する。【選択図】図9
