PROBLEM TO BE SOLVED: To provide a wheelchair storage device which can be installed in a saved space, can be applied to multiple kinds of vehicle, and has versatility.SOLUTION: A wheelchair storage device comprises: an interior attachment part 21 which is attached to an interior of a vehicle 10 a fixing arm 22 a movable arm 23 a wheelchair holding part 24 and an advancement/retreat driving part 25 for driving the movable arm 23 to advance and retreat. The fixing arm 22 is supported on the interior attachment part 21 so as to rotate in a lateral direction between a protruding position P1 and a storage position P2. The movable arm 23 is supported on the fixing arm 22 so as to lower while rotating and moving toward a tip side of the fixing arm 22. The advancement/retreat driving part 25 comprises a link arm 42 and a rotation driving part 43, and the rotation driving part 43. The rotation driving part 43 and the link arm 42 are connected to each other so as to be separable.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】省スペースで設置でき、複数種類の車両に適用して汎用性を有する車椅子収容装置を提供する。【解決手段】車両10の室内に装着される室内装着部21と、固定アーム22と、可動アーム23と、車椅子保持部24と、可動アーム23を進退駆動する進退駆動部25と、を備え、固定アーム22は突出位置P1と収容位置P2との間で横方向に回動するように室内装着部21に支持され、可動アーム23は固定アーム22の先端側へ回転しながら移動することで下降するように固定アーム22に支持され、進退駆動部25はリンクアーム42と回動駆動部43とを備えるとともに、回動駆動部43とリンクアーム42とが切り離し可能に接続されている。【選択図】図1
