Abstract: A main bag (3) stands independently and moves via free swiveling caster wheels 1 at four corners. A free swiveling caster wheel (1) is provided with a wheel (6), a yoke (7) connected to the wheel in a manner allowing the wheel to rotate, a radial bearing (8) with its outer ring (8B) connected to the yoke, a swivel shaft (9) connected to the inner ring (8A) of the radial bearing, and a mount (10) which holds the upper end of the swivel shaft fixed. The rotation axis (11) of the wheel is disposed with eccentricity with respect to the swivel axis (m), which is the center of rotation of the swivel shaft, allowing the yoke to swivel. The yoke and mount have a bend prevention gap (15) established between mutually opposing surfaces in close proximity. When a bending impact load acts on the swivel shaft, the yoke and mount press against each other at the bend prevention gap to support the bending impact force.

Abstract: A bag is wheeled in an upright orientation on casters 1 on its bottom of by using a grip 2. A shaft 9 is coupled to a wheel 6 by one bearing 8.
