Abstract:
PROBLEM TO BE SOLVED: To make smooth riding across a crossing of rails possible for a hanging wheel device that hangs down and moves a heavy movable wall.
SOLUTION: A pair of wheels 7, 7 that are rotative round first and second horizontal axes L1 and L2 being in eccentric in the traveling direction while intersecting the corresponding face at a right angle are provided at the external side face 4 of a base 2 of a hanging wheel main body A, and the number of wheels 7 are made eight altogether. At four corners of the base 2, weight- bearing rolling balls 8 are provided, and the number of balls are made four altogether. The horizontal distance F between the first horizontal axis L1 on a position close to the middle of the side of the base 2 and the rotational center P of the rolling ball 8 closest to the first horizontal axis L1 is made bigger than the distance S1 of a slit S on a rail R.
