Abstract

As shown in the reference figures 1 and 2 illustrating the usage state, this product is a box-end wrench that can be fitted onto the bolts of an auto tensioner without interfering with, for example, the crank pulley or belts attached to each pulley (water pump belt, generator belt) of an automobile engine, making it easy to attach and detach the bolts. In other words, this box-end wrench makes it possible to fit bolts in confined spaces during automobile maintenance, etc., without interfering with other parts.
