Disclosed is an invention for a drive wheel lifting device for a robot cleaner, capable of smoothly crossing obstacles as well as preventing a main body from being caught by the obstacles by vertically lifting a lifting support from a wheel driving part by a lifting operation part and varying the protruding height of a wheel member from the main body. The disclosed drive wheel lifting device for a robot cleaner comprises: a wheel member provided to protrude from a main body; a wheel driving part providing rotational force to the wheel member so that the wheel member rotates in contact with the ground; a lifting support provided in the main body so that the wheel driving part is fitted to be lifted; and a lifting operation part for adjusting the protruding height of the wheel member from the main body by vertically lifting the lifting support from the wheel driving part.

    승강작동부에 의해 승강지지대가 휠구동부로부터 수직하게 승강되어 본체에서 휠부재의 돌출 높이를 가변시킴으로써, 본체가 장애물에 걸림 방지될 뿐만 아니라 장애물을 원활하게 넘어갈 수 있는 로봇 청소기용 구동휠 승강장치에 대한 발명이 개시된다. 개시된 로봇 청소기용 구동휠 승강장치는 본체에 돌출 가능하게 구비되는 휠부재와, 상기 휠부재가 지면에 접한 상태로 회전되도록 상기 휠부재에 회전력을 제공하는 휠구동부와, 상기 휠구동부가 승강 가능하게 끼워지도록 상기 본체에 구비되는 승강지지대 및 상기 휠구동부로부터 상기 승강지지대를 수직하게 승강시켜 상기 본체에서 상기 휠부재의 돌출 높이를 조절하는 승강작동부를 포함하는 것을 특징으로 한다.
