Description

本開示の部材固定構造の一つの態様は、ネジ穴を有し中心軸方向に延びる筒状部を備えた第１部材と、前記筒状部に前記中心軸方向の一方側から嵌め込まれる開口部を有する第２部材と、前記開口部が前記筒状部に嵌め込まれた状態で前記ネジ穴にねじ込まれるネジと、を含み、前記第２部材は、前記開口部を有し前記第１部材と前記ネジとの間で前記中心軸方向に挟み込まれる台座部を有し、前記第１部材は、前記筒状部と離れた位置に配置され、前記中心軸と直交する方向に延びるヒンジ部と、前記ヒンジ部を挟んで前記筒状部と反対側に配置され、前記ヒンジ部を中心にして前記筒状部側に折り返し可能な折り返し部と、を有し、前記折り返し部は、折り返されたときに前記筒状部に前記中心軸方向の一方側から嵌め込まれる窪みと、前記窪みの周囲に配置され、折り返されたときに前記第２部材に前記中心軸方向の一方側から接する嵩上げ部と、を有し、前記嵩上げ部の前記中心軸方向の長さは、前記台座部の前記中心軸方向の一方側の端部と、前記筒状部の前記中心軸方向の一方側の端部との距離よりも長く、前記第１部材の前記中心軸方向の他方側に、前記第１部材が取り付けられる第３部材を有し、前記嵩上げ部は、前記第１部材と前記第３部材との取付面よりも前記中心軸方向の他方側に突出する突起部を有する。
One aspect of the member fixing structure of the present disclosure includes a first member having a tubular portion that has a screw hole and extends in the central axis direction, and an opening that is fitted into the tubular portion from one side in the central axis direction. and a screw to be screwed into the screw hole with the opening being fitted in the cylindrical portion, wherein the second member has the opening and the first member and The first member has a pedestal portion sandwiched between itself and the screw in the direction of the central axis, and the first member is arranged at a position separated from the cylindrical portion and extends in a direction perpendicular to the central axis; a folded portion disposed on the opposite side of the tubular portion with the hinge portion interposed therebetween and capable of folding back toward the tubular portion around the hinge portion, wherein the folded portion is folded back when folded back; a recess fitted into the cylindrical portion from one side in the central axis direction; a raised portion disposed around the recess and in contact with the second member from one side in the central axis direction when folded; and the length of the raised portion in the central axis direction is equal to the distance between the one end of the base portion in the central axis direction and the one end of the cylindrical portion in the central axis direction. longer than the distance and having a third member to which the first member is attached on the other side of the first member in the central axis direction; It has a projecting portion projecting to the other side in the central axis direction from the mounting surface .
