Abstract

A fixed case of a cable reel having a bolt hole perpendicular to an axis is formed without using a slide-type mold, by providing a first groove, which has a U-shaped notch opening from a lower end side of a mounting seat. The mounting seat is formed as a step in a radial direction from the area of the lower end of a fixed wall area and protrudes downwards along the direction of an axis from a peripheral wall of a fixed case. A step area covers an opening of a lower end side of the first groove, and a second groove has a U-shaped notch opening from an upper end side onto the step area. A bolt hole is formed in a direction perpendicular to an axis having an inner perpendicular surface of which the total periphery is closed by the first groove and the second groove. The bolt hole is formed by mating molds from the upper and lower sides and having a mold separating face at the center of the bolt hole.

Dependent claims

A cable reel having a movable body configured to be fixed to a steering wheel side of a vehicle and a fixed case mountable on a steering shaft cover configured to be fixed to a vehicle side, a flat cable being housed in a spiral form in an annular cable housing space formed by the movable body and the fixed case, said fixed case comprising:

a peripheral wall extending in a downward axial direction and having a lower fixed wall area, a mounting seat protruding in the form of a step from said lower fixed wall area;
a first groove having a U-shaped notch extending from and having an opening at a lower end of said mounting seat;
a step which covers an opening of said U-shaped notch;
a second groove having a U-shaped notch extending from an upper side of said step, said first and second grooves forming a bolt hole, said bolt hole having an inner peripheral face, the entire periphery of said inner peripheral face being closed by said first and second grooves;
and
a bolt passing through said bolt hole;
whereby a bolt inserted into said bolt hole is fastened into a screw hole of said steering shaft cover, said steering shaft cover interfitting with said fixed wall area, thereby fixing said fixed case onto said steering shaft cover.
