Abstract: A shift knob structure having a knob main body 1 formed by a skeleton 2 and a skin member 3 encapsulating over the skeleton 2. A switch 6 is provided on the knob main body 1. A conductor wire 7 is buried in the skeleton 2 and connected at one end to the terminal 6a of the switch 6. The skeleton 2 has a switch mounting portion 2f for mounting the switch 6 and a first support groove 2j formed in a bottom surface of the switch mounting portion 2f to insert therein the conductor wire 7. The skeleton 2 has a second support groove 2n formed in a lateral side thereof to insert therein the conductor wire 7. A press-fit hole 2k is formed open between the second support groove 2n and the first support groove 2j to pass the conductor wire 7 therethrough. As a result of this shift knob construction, the number of bend portions in a conductor wire is decreased, thereby reducing the number of fabricating processes and cost.
