Zusammenfassung:	It is supposed that N is defined as an optional natural number equal to or more than 3. A key wrench has a key section 5-2 engageable with a socket 2 of an N-sided polygon, and a proximal section 5-1. The key section 5-2 has N side surfaces that contain a first side surface 50-1, a second side surface 50-2 and an Nth side surface 50-N. The first side surface 50-1 is a tapered surface, and the Nth side surface 50-N is a non-tapered surface. Thus, the key wrench is provided to restrain a transformation of the surface of the socket and a generation of an excessive cam out load.
