PROBLEM TO BE SOLVED: To provide a wheelchair with a movement prevention device which can selectively prevent a rolling movement to a valley side by a simple operation without needing a labor even when facing forward or backward.SOLUTION: The wheelchair with the movement prevention device includes a ratchet wheel 12 fixed to a wheel 2, T-shaped pawls 14 having a proximal end pivotally supported and two claws to be selectively latched to the ratchet wheel 12 in a distal end thereof, and a lever 24 to turn the pawls 14, and is composed to be selectable among a state that the pawl 14 and the ratchet wheel 12 are made to latch by an operation of the lever 24 to restrain the forward rotation of the wheel 2, a state that the pawl 14 and the ratchet wheel 12 are made to latch to restrain the backward rotation of the wheel 2, and a state that the pawl 14 and the ratchet wheel 12 are not made to latch to enable the rotation of the wheel 2 in the forward and backward direction.COPYRIGHT: (C)2013,JPO&INPIT【課題】前向きと後ろ向きのどちらであっても選択的に、労力を必要とせずに簡単な操作によって、谷側への転がり移動を防止することのできる、移動防止装置付き車いすを提供する。【解決手段】車輪2に固定された爪車12と、基端部が軸支され先端部に爪車12に選択的に係止される2つの爪部を有する撞木状の爪14と、爪14を回動させるためのレバー24とを備え、レバー24の操作により、爪14と爪車12を係止させて車輪2の前進方向の回転を拘束する状態、爪14と爪車12を係止させて車輪2の後退方向の回転を拘束する状態、爪14と爪車12を係止させないで車輪2の前後方向の回転を可能にする状態のいずれかの状態を選択可能に構成した。【選択図】図3
