PROBLEM TO BE SOLVED BY A manual operation by a brake operation tool of a braking mechanism that applies a braking force to a wheel side and an automatic control by a control section, and it is possible to manually operate a brake operation tool even when the actuator fails Provide walking assistance vehicles.SOLUTION: The control unit controls the braking mechanism with an actuator 69 that switches between the braking state and the unlocking state of the braking mechanism 6, and the braking mechanism can be switched between the braking state and the released state by a manual operation with a brake operating tool A link mechanism for mechanically linking both of them, so that switching between the braking state and the disengaging state by the actuator and the switching between the braking state and the released state by the brake operating tool can be independently performed freely .(FIG.【課題】車輪側に制動力を作用させる制動機構のブレーキ操作具による手動操作と、制御部による自動制御とを両立可能であって、且つ、アクチュエータの故障時にもブレーキ操作具による手動操作が可能な歩行補助車を提供する。【解決手段】制動機構6のブレーキ状態と解除状態の切換を行うアクチュエータ69によって制動機構を制御する制御部と、ブレーキ操作具による手動操作よって制動機構のブレーキ状態と解除状態の切換操作が可能なように両者を機械的に連係させる連係機構を備え、アクチュエータによるブレーキ状態と解除状態の切換と、ブレーキ操作具によるブレーキ状態と解除状態の切換とを独立して自由に行うことが可能な融通手段を設ける。【選択図】図6
