ABSTRACT:
A strap wrench especially designed for removing oil filters. Both ends of the strap are retained in the wrench body and this forms a loop of the strap which passes around the oil filter. By applying a twisting action to the wrench body, the oil filter can be loosened with a minimum of torque applied to the wrench. The strap wrench comprises a strap structure which has its two ends formed into a loop structure. The two ends of the strap pass through both parts of a two-part holder structure. The two-part holder structure has one part inside the second part. Rotation of the inside part of the holder will lock the ends of the strap to the holder and further rotation of the holder then causes the strap to rotate the oil filter held in the loop of the strap.
