A surface that faces two portions is formed as an inclined surface, and is disposed in a space between the first portion and the second portion, and includes a third portion that sandwiches the cable between the first portion and the third portion. It is characterized by that.

  According to the cable fixing device of the present invention, the cable is sandwiched between the flat surface of the third portion and the V-shaped groove of the first portion, so that the pressing force from the flat surface of the third portion and the V-shaped groove are The pressing force from the pair of groove walls is received. Therefore, when the cable receives a pressing force from three directions, the thickness of the cable becomes somewhat thinner or thicker, and even if the cable protrudes large or small from the V-shaped groove, The cable can be clamped by the flat surface of the third portion and the pair of groove walls of the V-shaped groove.

Preferably, the third portion is formed such that a distal end portion protrudes from the first portion and the second portion when inserted into a space between the first portion and the second portion. .
Since the tip part of the third part protrudes from the first part and the second part, the ends of the first part and the second part do not get in the way when hitting with a hammer or the like.

It is desirable that a restriction portion is provided at the tip of the third portion so as to be caught in an opening portion formed by the first portion and the second portion when the third portion is retracted.
Even if the operator strongly hits the restricting portion and pushes in the third portion, the restricting portion is caught in the opening portion formed by the first portion and the second portion, so that the third portion is prevented from jumping out from the opposite side. be able to.
