Abstract: An improved mechanic's creeper including a flat, generally rectangularly configured platform, the four corner portions of which may be tapered for streamlining. The device includes a longitudinal support axis (axis of symmetry) along which are positioned head end and foot end casters, and a transverse support axis disposed nearer the foot end of the platform than to the head end and along which are positioned side casters. Upstanding fenders are disposed at the four caster locations for mounting the caster devices to the platform. A head rest is also provided at the head end of the device and extends over the fender disposed at the head end.
