PURPOSE: A hand cart having an endless track is provided to softly move without being caught in the step since a support roller unit supporting an endless track is axially-supported on a wheel frame in zigzag. CONSTITUTION: A hand cart comprises an endless track(121) and an angle control unit. The endless track is supported by a support roller unit. The support roller unit consists of two or more columns of support rollers(122). For the support rollers not to be caught in the step, the support rollers are axially-supported on the wheel frame(130) between front and rear main wheels(110) in zigzag. The angle control unit is installed on the wheel frame. The angle control unit controls the connection of a loading unit(210) and the wheel frame by the user's feet to control the angle of the loading unit.
