ABSTRACT:
A creeper for supporting the body of a worker and facilitating movement of the worker under and around an object such as an automobile. The creeper comprises a platform having a top surface and an underside, and four corner casters mounted on the underside of the platform for spacing the platform above a generally flat horizontal floor and for facilitating rolling of the platform on the floor. The casters are so spaced with respect to the platform that lines connecting adjacent casters define a quadrangle with a corresponding caster at each corner of the quadrangle. A fifth caster is mounted on the underside of said platform within said quadrangle.
