To provide a relatively lightweight moving mechanism which has an excellent linear motion stability in the back-and-forth direction and which is easy to rotate in all directions, and a wheelchair for assistance and a carrying truck using the same.SOLUTION: A wheelchair 1 for assistance includes: a seat 50 where a person subjected to assistance sits down; and a moving mechanism 5 to which the seat 50 is attached. In this wheelchair 1 for assistance, the moving mechanism 5 includes: a substantially rectangular placing part 10 on which the seat 50 is placed; four free casters 20 placed at the four corners of the placing part 10, respectively, at the ground-surface side; and a single omni wheel 30. The rotation shaft of a large wheel that forms the omni wheel 30 is located on the straight line in the moving direction passing through the mid point between the placed positions of the two free casters 20 placed at the one-end side (the rear-end side) in the back-and-forth direction among the four free casters 20. Moreover, a rotation shaft 32a of a large wheel 32 includes: the omni wheel 30 attached so as to be vertical to the back-and-forth direction; and a pressure adjusting part 40 that can adjust the grounding pressure between the omni wheel 30 and the ground surface.SELECTED DRAWING: Figure 1
