Abstract: A heel is readily and firmly fastened to the insole of a woman's heeled shoe. A fastening bolt (15) with a head (15a) is screwed through a washer (16) and an insole (12) into a reinforcing shaft (14) embedded in a heel (13). The reinforcing shaft (14) includes a thin lower portion (14a) having a small external diameter fixed to a thick upper portion (14b) having a large external diameter. The thick fastening bolt (15) is screwed into the thick portion (14b) such that the heel (13) is firmly fastened to the insole (12) with the reinforcing shaft (14).

Abstract: A cutter for use in an electrode tip dresser, which has a cutter holder for holding the cutter and dresses an electrode tip for a resistance welding apparatus, has a rising portion which has a cutting tooth for cutting a front peripheral portion of the electrode tip and a flat portion which faces a front end surface of the electrode tip. The flat portion has a single cutting tooth for cutting the front end surface of the electrode tip. The single cutting tooth extends from that central point of the cutter as and origin which coincides with an axis of rotation of the cutter holder towards a predetermined radial direction. An origin portion of the single cutting tooth further extends beyond the central point towards a direction which is opposite to the radial direction.
