The switch box 4 is screwed to the bracket 212 of the main body 21. FIG. 3 is an exploded perspective view showing details of the switch box. The switch box 4 includes a case 41, a slider 42 that slides inside the case 41, and a printed circuit board (hereinafter referred to as “PC board”) 43. The slider 42 is provided with a contact plate 45, and the case 41 and the slider 4 are provided.

The spherical portion 351 of the operation arm 35 is slidably fitted to the cylindrical surface 423 (see FIG. 1) formed therein. The block portion 421 of the slider 42 is provided with two front and one rear notches 424 to 426. The projecting pieces 451 to 453 of the contact plate 45 are fitted into these notches, and the projecting pieces 451 to 453 are provided.

(Shown by) is retained and supported by retaining. Three contact points 455 to 457 are formed on the lower surface of the contact plate 45 at the apexes of a triangle so that they are housed in the holes formed in the block portion 421 of the slider 42 behind these contact points. A spring 46 is arranged in a compressed state. Therefore, the three contacts 455 to 457 of the contact plate 45 are pressed against the PC board 43 by an appropriate spring force. Although illustration is omitted, a connection terminal is provided on a step portion behind the case 41.

FIG. 4 is a plan view showing the positional relationship between the circuit pattern of the PC board and the three contacts that come into contact with the circuit pattern. As shown in the figure, the PC board 43 has six conductor portions 431 to 436 separated from each other. Is equipped with. Right conductor part 43
1 always contacts the contact 457 of the contact plate 45, and the other conductors contact the contact 456 on the left side by the movement of the contact plate 45. In this example, the conductor portion 432 is for the first speed, 434 is for the second speed, 435 is for the third speed, 436 is for the fourth speed, and 433 is not used. The respective contacts are immovably placed at positions P, R, N, 2 and L of the shift lever, which are indicated by A in FIG.

Next, the operation of the shift device thus constructed will be described step by step. FIG. 5 is a plan view showing the operation of the lock plate of the shift device. In the figure, the inclination of each member caused by the inclination of the swing retainer is ignored. First, (A) shows the P position. At this position, the swing retainer 2 is in the most forward swing tilt state, and the shift lever 3 has the lock plate 5
It is positioned in the left-right direction by and is located in the overhanging groove portion 221a of the hole 221 of the gate plate 22. And
Although not shown in the drawing, the plate pin 71 of the inhibit plate 7 (see FIG. 1; the same applies to the detailed structure below) is fitted in the most notch of the cam surface of the inhibit hole 123 and is in the inhibit state.

When the shift lever 3 is pulled backward while pushing the button 37 of the knob 36 from this P position, the upper edge 75 of the inhibit plate 7 is pushed down by pushing the inhibit pin 34.
Is pushed downward, and the inhibit plate 7 has its long hole 7
2 is guided by the guide post 213 and descends, and the plate pin 71 is disengaged from the foremost notch of the cam surface of the inhibit hole 123. Further, since the shift lever 3 and the gate plate 22 are engaged with each other in the front-rear direction at the overhanging groove portion 221a of the hole 221, the swing retainer 2 has the shift lever 3
Along with this, it swings backward and reaches the D position shown in FIG. 2 through the R position and the N position. During this time, the rotation of the shift lever 3 in the left-right direction is as shown in FIG.
Of the rotation regulating surface 51 and the inner surface of the side wall of the main body 12 (in this example,
The bearing material is disposed on the surface), and the contact is slid. With this operation, as shown in FIG. 2, the manual valve connecting member 23 swings back and forth around the left-right axis X, and pushes the control rod 81 connected to the lower end thereof forward, so that the outer lever 83 is indicated by an arrow. As described above, the manual valve 86 is swung counterclockwise in the drawing, and the rod 87 is retracted by the swing of the manual shaft 82 and the detent lever 84 in the same direction. As a result, the manual valve 86 is switched. The moderation feeling in this operation is given by the spring force of the detent spring 88 that resists the operation of the detent lever 84. The operation so far is not particularly different from the operation of the shift device of the conventional automatic transmission.

When the shift lever 3 reaches the D position, the rotation restricting surface 51 of the lock plate 5 comes to a position matching the hole 121 formed in the side wall of the main body portion 21, so that the left and right rotation restricting of the lock plate 5 is released. The shift lever 3 is rotated counterclockwise by the biasing force of the torsion spring,
It shifts to the high-speed gear shift position (hereinafter referred to as the neutral position) in which the third and fourth speeds are arranged. Along with this, the rotation restricting surface 51 of the lock plate 5 enters into the hole 121 formed in the side wall of the main body 21 and is locked with respect to the stationary member 1. In this state, the slider 4 of the switch box 4
2 moves one step to the left, and the contact 456 of the contact plate 45 comes into contact with the conductor portion 433.

To select the first speed, the shift lever 3 is tilted to the left from the neutral position and then pushed forward. At the time of this operation, the spherical portion 351 of the operation arm 35 fixed to the shift lever 3 slides the slider 42 of the switch box 4 leftward. At this time, since the shift lever 3 is applied with a spring force for returning the neutral position by the torsion spring 66, the driver can feel the same resistance as the conventional manual shift device. Then, in the next forward pushing operation, as shown in FIG. 5B, the connecting portion 32 of the shift lever 3 moves forward along the long hole 53 of the lock plate 5, and the slider 42 of the switch box 4 moves. Move forward. At that time, the plunger 641 of the crossing sleeve 6 moves from the notch in the center of the cam surface of the detent block 223 to the notch in the front over the intermediate mountain portion, but the operation resistance due to the spring force of the plunger pushing-up spring at that time is increased. It is transmitted to the driver as a click feeling, and the same shift feeling as that obtained by the detent spring 88 and the cam notch 841 (see FIG. 3) at the time of switching from the P position to the D position can be obtained. Of course, the detent plunger mechanism 64 and the detent block 22
3 functions as a detent, and shift lever 3 is first
Hold in the fast position. With both of these movements, the slider 42 of the switch box 4 moves to the left front as shown in FIG.
Contacts the conductor portion 432, and the conductor portion 4 is connected through the contact point 457.
31 and the conductor portion 432 are electrically connected to each other to establish a connection relationship for outputting the first speed signal. On the other hand, since the manual valve connecting member 23 shown in FIG. 2 is immovable due to the restraint of the swing retainer 2 to the stationary member 1, the switching of the manual valve 86 via the control rod 81 does not occur.

Next, in order to select the second speed, the shift lever 3 is tilted leftward from the neutral position and then pulled backward. In this tilting operation to the left, the front-back swing of the swing retainer 2 is restricted, and only the shift lever 3 is not restricted, as described above. During this operation, the spherical portion 351 slides the slider 42 of the switch box 4 to the left. Then, in the next backward pulling operation, as shown in FIG. 5C, the connecting portion 32 of the shift lever 3 causes the lock plate 5 to move.
Move backward along the long hole 53 of the switch box 4
The slider 42 of is moved backward. With both of these movements, the contact 456 of the contact plate 45 shown in FIG.
The conductor portion 431 and the conductor portion 434 are electrically connected via 57, and a connection relationship for outputting the second speed signal is established. Also in this case, the manual valve connecting member 23 is the stationary member 1 of the swing retainer 2.
Since it is immobile due to restraint on the
No switching of the manual valve 86 via 1 occurs.

The third speed is selected by pushing the lever forward from the neutral position. Since the operation and function of each member at this time are clear from the above-described operation description, a step-by-step description is omitted to avoid redundancy, but the positions of the shift lever 3 and the lock plate 5 are shown in FIG. ), The contact 456 of the contact plate 45 moves forward along the path of, and is in a connection relationship of outputting the third speed signal.

The selection of the fourth speed is an operation of pulling the shift lever 3 backward, contrary to the case of the third speed. At this time, the position of the shift lever 3 becomes the position shown by the chain double-dashed line in FIG. 5 (D), the contact 456 of the contact plate 45 retracts in the path of, and is in the connection relationship of outputting the fourth speed signal.

The speed selection signal thus obtained is processed in the same manner as the speed change signal output according to the vehicle speed and the throttle opening in the D range in a normal automatic transmission, and is used for controlling the speed change solenoid valve. Used. Hereinafter, one embodiment will be briefly described. FIG. 6 shows a control flow in an electronic control unit for an automatic transmission incorporating such a manual transmission. Initial setting of steps S1 to S5 normally performed in a conventional automatic transmission, rotation speed calculation, and neutral. Start switch input processing, throttle opening calculation,
After the calculation of the oil temperature, the determination of the manual shift switch (MT switch), that is, the switch on / off in the switch box 204 and the determination of the on / off of the manual mode flag set during the manual shift are added in steps S6 and S7. ing. When the MT switch is on,
In steps S12 and S14, the manual mode flag is turned on and the manual shift map (MT map) is selected. In that subroutine, the shift diagram table (MSL) and the lockup diagram table (MSLP) are selected automatically in step S8. , S9 instead of S9, and the steps S17 and S18 of the manual gear shift corresponding to the steps S10 and S11 of the automatic gear shift are determined, and the processes of steps S19 to S23 corresponding to the determination are performed. It should be noted that steps S15 and S16 show a step of returning to the automatic shift mode by timer control, and step S13 shows a step of canceling the return to the step.

In the gear shift operation device of this embodiment, in the D range position, the shift lever 3 is located in the gear train on the high speed stage side, and the gear train on the low speed stage side and the gear train for automatic gear shifting are arranged on the left and right sides thereof. Therefore, when shifting from the neutral state of the shift lever 3 to another gear train, depending on the direction,
The operation resistances in opposite directions are loaded, respectively, and the arrangement is effective in preventing erroneous operation.

Although the present invention has been described in detail based on one embodiment, the present invention is not limited to the disclosure of the above embodiment, and various details can be obtained within the scope of the matters described in the claims. It is needless to say that the specific configuration of the above can be changed and implemented.
