To provide a holding device capable of holding a transport object with an opened upper part from either of outside and inside, and capable of holding the transport object with sufficient holding power.SOLUTION: A holding device includes: a frame 4 which can be attached to a base end side attachment; a pair of arm members 6 which are arranged side by side in a longitudinal direction, have lower parts 6a extending in a vertical direction, and have upper parts 6b attached to the frame 4 so as to move in the longitudinal direction; and a driving device 7 which changes a gap in the longitudinal direction between the pair of arm members 6. A holding portion 9 is rotatably attached to the lower part 6a of the arm member 6. On both faces in the longitudinal direction of the holding portions 9, contact faces with a transport object 50 are formed. The holding device includes a maintaining device which maintains a state where the lower parts 6a of the arm members 6 extend in the vertical direction even when the gap in the longitudinal direction between the pair of arm members 6 is changed.SELECTED DRAWING: Figure 2

    【課題】上部が開口した運搬物を外側および内側のどちらからでも保持することが可能であるとともに、十分な保持力で運搬物を保持することが可能な保持装置を提供する。【解決手段】基端側アタッチメントに取り付け可能なフレーム4と、左右方向に並んで配置されて、上下方向に延びる下部6aを有し、上部6bが左右方向に移動可能にフレーム4に取り付けられた一対のアーム部材6と、一対のアーム部材6同士の左右方向の間隔を変更する駆動装置7と、を有する。アーム部材6の下部6aに保持部9が回転可能に取り付けられている。保持部9の左右方向の両面には、運搬物50との接触面が形成されている。一対のアーム部材6同士の左右方向の間隔が変更されても、アーム部材6の下部6aが上下方向に延びた状態を維持する維持装置を有する。【選択図】図2
