Abstract

See full text

The wheelchair includes a seating portion, body frames that support the seating portion, wheels that are rotatably supported by the body frames, an engaging portion, a left brake that brakes a left rear wheel, and a coupling portion that couples the engaging portion and the left brake to each other. The engaging portion is capable of switching between an engagement attitude for engaging a vehicle body member that forms an opening of a vehicle and a disengagement attitude for releasing the engagement with the vehicle body member. The coupling portion transmits the movement of the engaging portion to the left brake when the engaging portion makes an attitude change from the disengagement attitude to the engagement attitude. This operates the left brake when the attitude of the engaging portion switches from the disengagement attitude to the engagement attitude and brakes the left rear wheel.
