DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a first embodiment of the present invention will be described in detail with reference to FIGS. Reference numeral 1 denotes a knob main body of the shift lever knob, which comprises a skeleton 2 on the inner side and a skin member 3 on the outer side. The skeleton 2 has a handle 2c and a hollow rod 2
and d are formed of a hard resin. The skeleton 2 is fitted at its center with a shaft hole 2a for inserting a shaft (not shown), a tubular member (not shown) for inserting a push button (not shown) and a switch (not shown). A cylindrical member installation hole 2b to be attached is formed.

The shaft hole 2a is continuous with the push button installation portion 2e of the cylindrical member installation hole 2b as shown in FIG. The tubular member installation hole 2b includes the push button installation section 2e where the push button is arranged and the switch installation section 2f where the switch is arranged. The cylindrical member installation hole 2b has an inner wall formed with a locking hole 2s with which the claw of the cylindrical member engages. Push button installation part 2
“e” is a horizontal hole communicating with the shaft hole 2a. The switch installation portion 2f has a holding groove 2g into which one end of the conductive wire 4 is fitted. One end of the conducting wire 4 is located within the switch installation portion 2f.
A pin-shaped terminal of the switch is pressed into the conductor 4.

As shown in FIG. 2, a holding groove 2h is formed on a side surface of the holding portion 2c so that a substantially central portion of the conducting wire 4 is press-fitted. 2j is a through-hole for passing the conducting wire 4 of the holding groove 2h into the switch installation portion 2f. Hollow bar 2
As shown in FIG. 2, a holding groove 2k into which the conductive wire 4 is press-fitted is formed in a rail shape on the surface of d. The holding groove 2k is
As shown in FIG. 4, an inner wall 2p slightly protruding from the bottom surface 2n of the notch 2m, and an outer wall 2q protruding higher than the inner wall 2p.
And formed.

The inner wall 2p forms the plurality of cutouts 2m. A jig for holding the conductive wire 4 can be inserted into the notch 2m. The width d of the notch 2m is longer than the width of the support of the jig. The outer wall 2q has a hollow rod-like portion 2d.
Are long plate-like projections formed on the surface of the substrate. The outer wall 2q
Is a recess 2r in which the resin material of the skin member 3 enters the lower end surface.
Is formed.

The skin member 3 is made of, for example, a vinyl chloride resin or a foamed resin. Is provided in a state where the upper part is covered. The skin member 3 is
The handle cover portion 3b covers the entire grip portion 2c, and the wire cover portion 3c covers the space between the outer walls 2q of the hollow rod portion 2d.

The skin member 3 of the handle wrapping portion 3b is for improving the feel when the driver grips the knob body 1. The conductor wrapping portion 3c is integrated with the handle wrapping portion 3b,
At the same time, it is formed by molding. The wire covering portion 3c
Has a role of both a fixing member for fixing the conductor 4 to the hollow rod portion 2d and an insulating member for the conductor 4. Hollow bar 2d
The skin member 3 provided at the notch is connected to the conducting wire 4 at the notch 2m with a jig.
, And molded with resin. The skin member 3 formed in this manner is, as shown in FIG.
The conductor 4 is exposed.

The conductor 4 is made of, for example, a thick copper wire.
One end is connected to the switch, and the other end constitutes a terminal projecting from the skeleton 2 as shown in FIG. The switch is an overdrive operation switch formed of, for example, a push button switch. The tubular member into which the switch and the push button are fitted is fixed to the skeleton 2 by engaging the claws with the locking holes 2s shown in FIG.

A hollow rod-shaped portion 2d in which the skin member 3 is resin-molded
A cylindrical cover 5 made of metal or the like is inserted into the cover.
The cover 5 may be a resin member or a resin material plated with metal, and the material is not particularly limited.

The embodiment of the present invention is configured as described above, and its assembling procedure and its operation will be described in detail.

First, the skeleton 2 is molded with a hard resin. 2
The lead wire 4 is inserted into each through hole 2j of the skeleton 2, one end is fitted into the holding groove 2g, the central part is fitted into the holding part 2h, and the other end is fitted into the holding groove 2k. Conductor 4 has a notch 2m
At a position slightly floating from the bottom surface 2n.

Next, the conductor 4 in the desired notch 2m is supported by a jig, and the handle 2c of the skeleton 2 and the upper portion between the two outer walls 2q are covered with a soft resin so as to cover the skin. 3 is molded. At this time, the skin member 3 on the hollow rod portion 2d
The resin material described above enters the bottom surface 2n of the notch 2m and the recess 2r below the conductive wire 4 and hardens. For this reason, the skin member 3 on the hollow rod portion 2d does not come off from the skeleton 2 without covering the entire hollow rod portion 2d. Since the skin member 3 is made of an insulating material, an insulating sheet or tube that covers the conductive wire 4 is not required, and the number of parts and the number of assembling steps can be reduced.

The inner wall 2p of the skeleton 2 is formed with a plurality of cutouts 2m, so that when the skin member 3 is molded, a resin material flows under the conductive wire 4 and the conductive material of the skin member 3 is covered. The wrapping portion 3c is prevented from peeling off from the skeleton 2. Further, since the plurality of cutouts 2m are formed in the inner wall 2p, the jig can support the conductive wire 4 at a desired position when the skin member 3 is molded by a mold, so that workability is good. The jig support 3a is formed on the skin member 3 by molding the display member 3 with the jig with the conducting wire 4 therebetween.

Hollow rod-shaped portion 2d in which skin member 3 is resin-molded
, The cover 5 is inserted. The jig support 3a can be hidden by inserting the cover 5 into the hollow bar 2d. The conductive wire 4 wired to the hollow rod portion 2d is covered with the skin member 3 and is insulated, so that the cover 5 can be formed of metal.

A push button and a switch are fitted into the tubular member, and the tubular member is fitted into the tubular member installation hole 2b. At this time,
The tubular member is fixed by engaging the claw with the locking hole 2s, and the terminal of the switch is engaged with the conducting wire 4 to be electrically connected.
