<p>PURPOSE:To make it possible to stably secure an electric wire by forming a fixed shaft and a body in such a way that the diameter of the fixed shaft is larger than that of the body, and projecting the portion of an electric wire winding shaft on the fixed shaft side to outside the other portions of the electric wire winding shaft. CONSTITUTION:A fixed shaft 9 and a body 1 are formed in such a way that the diameter of the fixed shaft is larger than that of the body. Further, the width of the portion of the body adjacent to the threads of the fixed shaft 9 is enlarged, and the area from the wide portion of the body 1 to a first portion 2, 2' of an electric wire winding shaft, is projected to outside the other portions 3, 3', 4, 4' of the electric wire winding shaft. An electric wire 18 is wound around the portions 2, 2', 3, 3', 4, 4' of the electric wire winding shaft of the body 1. The electric wire is wound around an electric wire clamping section in the position of the portion 2, 2' of the electric wire winding shaft, and a tightening nut 11 is tightened. As a result, the electric wire 18 is clamped in a recess in the projected and recessed surface 13 of the tightening nut 11; therefore, the electric wire 18 is prevented from slipping when it is tightened. Further, the large diameter of the fixed shaft 9 enhances strength and stability.</p> |
