When the protrusion 49 pushes the actuator 67 of the limit switch 60 on the front side of the vehicle body to turn it on, the gear position is raised (+) by one step, and conversely, the actuator 67 of the limit switch 60 on the rear side of the vehicle body is moved. If the gear is turned on, the gear shifts by one (-)
/ T mode can be realized.

The operation of the above embodiment will now be described.
The operation in the T mode is performed by the fitting portion 43 of the shift lever upper body 4.
With the upper end portion of the shift lever lower body 3 integrally fitted, the shift lever 1 is rotated forward and backward along the shift groove 5 via the shaft support portion 20 of the base bracket 2 around the shaft portion 33. Normal operation that moves is sufficient. When the shift lever 1 moves, as shown in FIG. 8, the sliding member 47 moves between the crests and troughs of the moderation forming portion 28, so that a feeling of moderation occurs.

Therefore, for example, in the P range, the knob 5
When the push button 56 of No. 1 is pushed, the compression rod 16 descends against the force of the coil spring 55, the lower rod 22 is pushed in, and the position pin 19 is moved to the long hole 18
Lower along. When the push button 56 is released, the lower rod 22 is caused by the coil spring 23, and the compression rod 16 is caused by the coil spring 55.
Each of them is pulled up, and the position pin 19 also moves above the elongated hole 18.

In the M / T mode operation, the shift lever 1 is positioned in the D range via the knob 51, and when the knob 51 is tilted to the side at that position, the shift lever upper body 4 receives the bearing portion 40 at the lower end thereof. , 40 about the base 4
The limit switch 21 which was pressed by the part 42a of 2 to be turned on or off is turned on or off, the protrusion 49 projects from the window hole 66 to the outside of the side wall 6, and the unit bracket 64 is attached to the side wall 6. It faces the limit switch 60 fixed by.

At this time, the lower end portion of the compression rod 16 slides from the receiving surface 24 of the lower rod 22 to the sliding contact portion 25.
Since it always moves so that it can come into contact with the A / T mode and the M
It is possible to switch the / T mode and operate the M / T mode. Further, the window hole 45 of the base portion 42 of the shift lever upper body 4 is formed large so as not to come into contact with the position pin 19.
Both ends of both of the two side wall portions 6 and 6 are abutted against the detent notch portions 7 and 7 formed in the same shape, respectively, so as to strengthen the support strength. Since the flange portion 48 of the fitting portion 43 of the shift lever upper body 4 releases the pressing force of the lock member 12, the lock member 12 swings by its own weight, and the lever portion 13 of the lock member 12 swings by the engagement hole 15 of the side wall portion 6. Therefore, the shift lever lower body 3 is fixed to the D range. Further, as shown in FIG. 9, the sliding member 47 slides laterally from the valley portion 28a of the D range of the moderation forming portion 28 with a feeling of moderation and slides in the central portion (valley portion 29a) of the neutrality regulating portion 29.
Then, the shift lever upper body 4 is held at the neutral position of the M / T mode.

Then, if the knob 51 is moved to the front side of the base bracket 2, the shift lever upper body 4 is moved to the collar 2.
5, the protrusion 49 abuts the actuator 67 to turn on the acceleration (+) side limit switch 60 to raise the gear position. When this operation is performed in reverse, the limit switch 60 on the (-) side is turned on to reduce the gear position. At this time, as shown in FIG.
The sliding member 47 moves from the central portion of the neutral restriction portion 29 to the inclined surface portion 2
9b to compress the coil spring 46 and turn the knob 5
When the hand is released from 1, the sliding member 47 is returned to the central portion (valley portion 29a) of the neutral restriction portion 29 by the force of the coil spring 46, and the neutrality of the shift lever upper body 4 is maintained.

Then, in order to return from the M / T mode to the A / T mode, the knob 51 is rotated to return the shift lever upper body 4 to the original state, and the fitting portion 43 is moved to the shift lever lower body. 3 is engaged with the upper part of the window 3,
6 to the inside of the side wall portion 6, and a portion 42a of the base portion 42
When the limit switch 21 is turned on or off by being pressed by, the lower end portion of the compression rod 16 contacts the receiving surface 24 via the guiding portion 25 of the lower rod 22, and the fitting portion 43 pushes the lock member 12. The lever portion 13 is rotated to be released from the engagement hole 15 of the side wall portion 6. Therefore, by moving the knob 51 to the front or rear, the shift lever upper body 4 and the shift lever lower body 3 are moved.
Can operate the normal A / T mode that rotates back and forth as a unit. When the M / T mode and the A / T mode are switched while the shift lever upper body 4 is not in the neutral position or the D position, the protrusion 49 causes the edge portion of the window hole 66 of the side wall portion 6. To prevent rotation. As a result, the sliding member 47 moves from the position of the imaginary line in FIG. 9 to the position of the solid line.

Thus, according to this embodiment, when the A / T mode is switched to the M / T mode, only the shift lever upper body 4 rotates so that the shift lever lower body 3 remains in its original state. Therefore, even the position pin 19 does not fall down, and therefore, it is not necessary to form a space in which the position pin 19 moves, so that the lateral width of the base bracket 2 can be reduced.

Further, in the A / T mode, a feeling of moderation is given at each shift position, in the M / T mode, the shift lever upper body 4 is returned to the neutral position, and the A / T mode is switched to the M / T mode. Since a single sliding member 47 is used to give a feeling of moderation, it is possible to reduce the number of parts and save space.

Position pin 19 that engages with the shift groove 5
Always works together with the shift cable, and because the position pin 19 is supported by the detent notch 7 with both ends, it is possible to reduce the error between the shift position on the indicator and the shift position on the mission side. The play of the shift lever 1 can be reduced. Furthermore, the shift lever lower body 3 is engaged with the base bracket 2 by the lock member 1
Since 2 is provided, it is possible to prevent the shift lever lower body 3 and the shift cable from moving when the M / T mode is switched.

[0030]

According to the present invention described above, the M / T
Since the position pin is prevented from falling when switching to the mode, there is no need to take space for that movement,
Therefore, the width of the base bracket 2 can be reduced and the size can be reduced.

Further, since the position pin that engages with the position groove always operates integrally with the shift cable, the play can be reduced. Further, since the shift lever lower body 3 is provided with the lock member that engages with the base bracket 2, M
It is possible to prevent the shift lever lower body 3 and the shift cable from moving when the / T mode is switched.

Further, an A / T mode moderation portion and M /
