To provide an electric wheelchair capable of restricting drive of driving wheels when a wheelchair body travels in a fixed direction.SOLUTION: An electric wheelchair includes free wheels 20, a motor for driving the free wheels 20, a driving and controlling part for driving/controlling the motor, a support part for supporting the free wheels 20 pivotably following a travelling direction of a wheelchair body frame, and a transmission mechanism for transmitting power or signals between the motor and the driving and controlling part. The transmission mechanism includes rotary terminals 92a1-92b5 connected to the motor and provided to a rotary shaft 90 over a predetermined range in a circumferential direction, which rotates around a pivot axis S2 together with the free wheels 20, and main brushes 94a1-94b5 connected to the driving and controlling part, which can slidably come in contact with the rotary terminals 92a1-92b5 following the rotation of the rotary shaft 90.SELECTED DRAWING: Figure 4
【課題】車体本体が一定の方向へ走行する場合において駆動輪の駆動を制限することができる電動車椅子を提供する。【解決手段】電動車椅子は、自在輪20と、自在輪20を駆動するモータと、モータを駆動制御する駆動制御部と、車体フレームの進行方向に追従して自在輪20を旋回可能に支持する支持部と、モータ及び駆動制御部の間で電力又は信号を伝達する伝達機構とを備える。伝達機構は、モータに接続され自在輪20とともに旋回軸S2回りに回動する回動シャフト90に周方向所定範囲に亘って設けられた回動端子92a1~92b5と、駆動制御部に接続され回動シャフト90の回動に応じて回動端子92a1~92b5に摺接可能な主ブラシ94a1~94b5とを備える。【選択図】図4
