PROBLEM TO BE SOLVED: To facilitate attachment of a walking assistance device for assisting walking.SOLUTION: A walking assistance device, which is attached to a users leg and which assists the users walking by applying an assist force, includes a holding unit which comprises a holding detection means for detecting the users right and left holding states and an operation instruction means capable of providing instructions on at least either a hold-up operation or a hold-down operation. Characteristically, the walking assistance device can perform attachment/detachment processing in which leg parts are extended or contracted by applying a driving force to a first actuator on the basis of the instructions of the operation instruction means, when both right and left sides of the holding detection means are in a holding state.COPYRIGHT: (C)2014,JPO&INPIT【課題】歩行をアシストする歩行補助装置において装着の容易化を図る。【解決手段】本発明は、ユーザーの脚部に装着されアシスト力を加えることでユーザーの歩行を補助する歩行補助装置において、ユーザーの左右の把持状態を検出する把持検出手段と、持ち上げ操作もしくは持ち下げ操作の少なくとも一方を指示可能な動作指示手段を備えた把持部を有し、把持検出手段の左右両方が把持状態であるとき、動作指示手段の指示に基づいて、第1アクチュエータに駆動力を加えることで脚パーツを伸ばす、もしくは縮める着脱処理を実行可能とすることを特徴とする。【選択図】図4
