Description

[Brief explanation of drawings]

The drawings show an embodiment of the present invention; FIG. 1 is a cross-sectional view showing the main parts of a column shift type shift operation mechanism, FIG. 2 is a plan view of FIG. 1, and FIG. 3 is a column shift type shift operation mechanism. FIG. 4 is a shift pattern diagram of the shift operation mechanism; FIG. 5 is a state in which the gear shift operation mechanism has been selected from the state shown in FIG. 1 to the neutral position on the reverse shift position side. FIG. 6 is a schematic diagram showing a state in which the shift operation is performed from the state shown in FIG. 5 to the 5th shift position side, and FIG. 7 is a schematic diagram showing the state shown in FIG. plan view of
FIG. 8 is a plan view when the state shown in FIG. 7 is returned to the neutral position. 4...Control shaft, 16...Interlocking arm, 17...Stopper.

Claims (1)

[Scope of utility model registration request] Shift and select operations are performed by rotating the control shaft disposed along the steering column around its axis and pushing and pulling it in the axial direction, and the predetermined forward shift position and reverse shift position are neutral. A column shift type speed change operation mechanism that is set to shift patterns that are opposite in position,
An interlocking arm is fixed on the axis of the control shaft, and a stationary member supporting the control shaft is movable in the same direction by interference of the interlocking arm when a selection operation is made to the neutral position. A stopper is arranged so that it always returns to its original position, and this stopper also acts as a stopper when the control shaft is returned from one of the opposing shift positions to the neutral position. A column shift type shift operation mechanism for a gear transmission configured to interfere with the interlocking arm to prevent overshifting to the other shift position.
