項(1)記載の手押し運搬車。[Scope of Claim for Utility Model Registration] (1) A front wheel made of casters is equipped at the front of a vehicle body having a hand-held handle, a rear wheel is equipped at the rear of the vehicle body, and the vehicle body between the front wheels and the rear wheels is used as an escalator. In a handcart that is supported by multiple step corners and can be raised and lowered as the escalator goes up and down, when moving the cart with the wheels in contact with the ground, the horizontal rotation support part of the front wheels is used. A handcart that can freely rotate in any direction and is provided with a rotation regulating member that prevents the front wheels from rotating in the horizontal direction due to their own weight when descending on an escalator without touching the front wheels. (2) A scooping roller is provided which is located in front of the front wheels and the rear wheels in the direction in which the vehicle moves, and comes into contact with the escalator comb before the front wheels and the rear wheels when lowering the transport vehicle from the escalator. 1) Hand truck as described.
