Claims

[Claims for Utility Model Registration] 1. A vertical mounting piece on the upper edge of the opening of the spherical cover, a horizontal mounting piece on the lower edge of the opening, a bearing piece on the left and right edges of the opening, and a leg piece on the horizontal mounting piece. By inserting and fixing both left and right ends of a spherical axle on which a wheel is rotatably fitted into the bearing pieces of the integrally formed covering frame, the wheel is positioned corresponding to the spherical covering part, and The relationship between the wheels and the leg pieces is such that when the leg piece is grounded on the floor and the horizontal mounting piece is placed horizontally on the floor, the wheel does not touch the floor but floats up. A caster that is characterized by being set and becoming. 2. An annular groove with a substantially V-shaped cross section is formed by the inner peripheral wall and the outer peripheral wall, and a plurality of cylindrical parts are provided within the annular groove at intervals equal to the width of the cylindrical parts, and each outer end side thereof has the required width. A pair of wheel profile bodies whose lengths protrude from the end faces of the inner and outer circumferential walls are integrated by closely engaging the cylindrical portions of each other with the annular grooves of the other side, and the spherical portions of the inner and outer circumferential walls are integrally formed. Therefore, there is provided a swivel wheel in which the sphere of an axle with a sphere is covered, and the axle rod of the axle with a sphere is projected outward through a cavity in which an inner circumferential wall surrounds and opens, and a vertical mounting piece is provided on the upper edge of the opening of the spherical cover. , a horizontal mounting piece having leg pieces on the lower edge of the opening, and a cover frame integrally formed with bearing pieces formed on the left and right edges, and both left and right ends of the former ball-equipped axle are inserted into the latter bearing pieces. By fixing, the wheel is positioned corresponding to the spherical covering part, and the relationship between the wheel and the leg piece is such that when the leg piece is grounded on the floor and the horizontal mounting piece is made horizontal to the floor, the wheel is A caster characterized by being set so that it floats without touching the floor surface. 3 Attach the casters according to claim 1 to the four corners of the bottom of the bag body or to the two corners on the left and right sides, and place the vertical and horizontal attachment pieces of the cover frame against the vertical and horizontal bottom sides of the bag body. The bag is attached by being fixed in place, each leg piece is located on the inside, each wheel is located on the outside, and a handle is attached to the upper surface and/or both or one of the left and right sides of the bag body.
