The present invention relates to an expandable trailer for forming an expandable space connected to an inner space by expanding an inner space of a traction body to at least one of both sides of the traction body. To achieve the purpose of the present invention, the expandable trailer includes: the traction body including an inner space forming an activity area of a user and a side opening unit in which at least one of a left side unit and a right side unit in the inner space is opened to correspond an expansion direction of a trailer vertical to a moving direction of the trailer, wherein the inner space is a hollow housing; a side plate member connected to rotate to the traction body to open and close the side opening unit, wherein the side plate member can protrude from the floor of the inner space in the expansion direction of the trailer according to opening of the side opening unit; and an expansion member arranged in the inner space and connected to the side plate member protruding in the expansion direction of the trailer from the floor of the inner space to slide, thereby forming the expandable space connected to the inner space.

    본 발명은 견인바디의 내부공간을 견인바디의 양측면부 중 적어도 어느 하나로 확장시켜 내부공간과 연통되는 확장공간을 형성하기 위한 확장형 트레일러에 관한 것이다. 이를 위해, 확장형 트레일러는 중공의 함체이고 사용자의 활동영역을 형성하는 내부공간과 트레일러의 이동방향과 수직인 트레일러의 확장방향에 대응하여 내부공간의 좌측면부와 우측면부 중 적어도 어느 하나가 개구되는 측면개구부가 포함되는 견인바디와, 측면개구부를 개폐하도록 견인바디에 회전 가능하게 결합되되 측면개구부의 개방에 따라 내부공간의 바닥에서 트레일러의 확장방향으로 돌출 가능한 측판부재와, 내부공간에 배치되고 측면개구부의 개방에 따라 내부공간의 바닥에서 트레일러의 확장방향으로 돌출되는 측판부재에 슬라이드 이동 가능하게 결합되어 내부공간과 연통되는 확장공간을 형성하는 확장부재를 포함한다.
