Reference numeral 26 designates a shift switch which is a switch attached to the right side wall portion 1b of the base frame 1. This is, for example, a slide type switch, and its operating shaft 2
6a is engaged with a connecting shaft 27 protruding from the right end surface of the second pivot 10, so that the shift switch 26 is switched by displacement of the second pivot 10 in the front-rear direction. The switching state of the shift switch 26 is changed depending on the front and rear positions of the shift switch 10. The hydraulic mechanism is controlled by electric signals generated based on the switching states of the select and shift switches 21 and 26 corresponding to each position of the operating lever 2 as described above, and the vehicle gear shift is performed by the operation of this hydraulic mechanism. machine (none shown)
is selectively switched to any one of the 1st to 4th speed positions, the drive position, and the reverse position. Reference numeral 28 denotes a guide member fixed to the left end of the first pivot 7, and its circumferential surface along the circumferential surface of the first pivot 7 includes a vertical groove 29a extending vertically and a horizontal groove 29b extending horizontally. Cross-shaped guide groove 2
9 is formed. Reference numeral 30 denotes a guide pin fixed to the base frame 1 so as to protrude toward the guide member 28, and its tip is positioned within the guide groove 29 when the first pivot 7 is in the middle position (see FIG. 5). ), when the control lever 2 is in the left and right positions, the guide member 28 is located on the right and left sides of the guide member 28, and when the operating lever 2 is in the neutral position and the second pivot 10 is in the middle position, the guide Of the grooves 29, they are particularly located within the lateral groove portions 29b (see FIG. 2). As a result, regarding the operation of the operating lever 2 in the select direction, that is, the left-right displacement of the first pivot 7, the operating lever 2
The operation is allowed only when the guide member 28 is in the neutral position, that is, when the lateral groove 29b of the guide member 28 is aligned with the guide pin 30, and when the operating lever 2 is in the front and rear positions, the lateral groove 29b is in the guide position. pin 30
If they do not match, the side wall portion of the guide member 28 comes into contact with the guide pin 30 and its operation is blocked. Regarding the shift direction operation of the operating lever 2, that is, the rotational displacement of the first pivot shaft 7,
Since the guide member 28 does not come into contact with the guide pin 30 regardless of whether the first pivot shaft 7 is in the left, middle, or right position, its operation is allowed freely. 31 and 3
Compression springs 2 have approximately the same strength, and these springs are fitted between the left side wall 1a and the guide member 28 of the base frame 1 and between the right side wall 1b and the first pivot 7, respectively. installed between the moderation member 17 of 1,
When the first pivot shaft 7 is displaced from side to side by operating the operating lever 2 in the select direction, the first pivot shaft 7 is biased to return to the middle position. Reference numeral 33 denotes a regulating opening, which is formed in the regulating wall 1d extending from the upper end of the right side wall 1b of the base frame 1, and is located in the lower half of the rear side of the rectangular opening 33a as shown in FIG. It is formed by continuously forming escape notches 33b. 34 is the connecting member 3
This is a regulating pin protruding from a portion near the upper end, which enters into the upper half of the rectangular opening 33a when the operating lever 2 is fully operated in the opposite direction of arrow C.
Then, when the operating lever 2 is operated in the opposite direction of arrow D (direction of the R position) from that position, the regulating pin 34
comes into contact with the rear edge of the rectangular opening 33a to prevent its movement, thereby preventing the operating lever 2 from inadvertently entering the R position. Further, in order to put the operating lever 2 into the R position to move the vehicle backward, the regulation pin 34 is inserted into the rectangular opening 33a.
When the control lever 2 is pushed down against the elastic force of the compression spring 16 and operated in the opposite direction of arrow D when it comes into contact with the rear edge, the regulation pin 34 moves into the relief notch of the regulation opening 33. 33b so that the operating lever 2 can reach the R position.
Reference numeral 35 denotes a locking surface portion formed on the first moderation member 17, which is formed by cutting a predetermined portion of the outer peripheral surface oriented in the axial direction so as to rise in the radial direction. On the other hand, 36 is an engagement arm having an engagement claw 36a protruding from one end that engages with the engagement surface portion 35.
is rotatably supported on the right side wall portion 1b of the base frame 1, and is constantly biased in the direction of arrow E by a torsion coil spring 37. Then, when the operating lever 2 is operated in the opposite direction of arrow C to bring the first pivot 7 to the left position, the first moderation member 17 engages the engagement claw 36.
a, and from this state, when the operating lever 2 is operated in the opposite direction of arrow D (i.e., in the direction of the R position) while pushing down as described above, the first moderation member 17 rotates at the same time. Therefore, the locking surface portion 35 of the first moderation member 17 comes into contact with the engagement claw 36a of the engagement arm 36 when the regulation pin 34 slightly enters the relief notch 33b. Reference numeral 38 denotes a receiving member attached to the right side wall 1b of the base frame 1, which has a downward substantially U-shape with a pair of legs 38a extending downward, and the engagement arm 36 is placed between the legs 38a. The other end is allowed to enter, and a limit of rotation of the engagement arm 36 biased in the direction of arrow E in the same direction is determined. Reference numeral 39 denotes a locking member pivotally supported on the right side wall 1b of the base frame 1, which has a locking pawl 39a at its lower part that engages with the other end of the engaging arm 36;
The lock position where the lock pawl 39a engages with the other end of the engagement arm 36 to prevent rotation of the engagement arm 36 in the opposite direction of arrow E (see the solid line in FIG. 6), and the pivot 3
It is possible to rotate between a lock release position where the lock is released by rotating in the direction of arrow F about 9b. Reference numeral 40 denotes a solenoid fixed to the base frame 1, which is energized to suction the plunger 41 when, for example, the vehicle transmission is switched to the reverse position. Reference numeral 42 denotes a connecting pin, which is provided at the tip of the brunge 41 so as to protrude in the radial direction, and is inserted and connected into the long hole 43 of the boss portion 39c protruding from the locking member 39, so that the brunge 41 is When attracted, the locking member 39 is rotated in the direction of arrow F to unlock the engagement arm 36 and allow rotation in the opposite direction of arrow E.

Next, the operation of the above configuration will be explained. First, to put the vehicle transmission into 1st gear to start the vehicle, tilt the operating lever 2 in the neutral position fully in the direction of arrow C in the select direction, and then operate it in the direction of arrow D in the shift direction. Put it in 1st gear position. By operating in the select direction, the operating lever 2 rotates around the second support pin 14 of the second pivot 10, displacing the first pivot 7 in the opposite direction of arrow A, and bringing it to the right position. , the select switch 21 is switched, and the first moderation member 17 and the guide member 28 are also displaced in the opposite direction of arrow A, so that the moderation ball 18 is moved from the first moderation member 17 to the first moderation member 17 .
The guide pin 30 is in pressure contact with the flat surface portion 17a of the guide member 28, and the guide pin 30 is inserted through the lateral groove portion 29b of the guide member 28 and protrudes toward the left outer side of the guide member 28. Further, due to the subsequent operation in the shift direction, the operating lever 2 rotates around the first pivot shaft 7, so that the second pivot shaft 10 is displaced in the direction of arrow B and reaches the front position, thereby shifting the shift switch. 26 is switched, the moderation ball 25 comes to engage with the recess 23a of the second moderation member 23, and the operating lever 2 is held at the first speed position. Then, based on the switching states of the select and shift switches 21 and 26 at this time, the vehicle transmission is switched to the first speed via, for example, a hydraulic mechanism. Next, from this state, change the vehicle transmission to 2.
In order to switch to the second speed position, the operating lever 2 should be fully operated in the opposite direction of arrow D to pass through the neutral position and enter the second speed position. As a result, the first pivot 7 rotates while maintaining the right position, the second pivot 10 is displaced in the opposite direction of arrow B, the shift switch 26 is switched, and the moderation ball 25 is moved to the second moderation member. 23
The operating lever 2 is engaged in the recess 23c of the
hold in the fast position. Further, when switching the vehicle transmission from 1st speed to 3rd speed, for example, the following procedure is performed. First, when the operating lever 2 is operated in the direction opposite to the arrow D, the second pivot 10 is displaced in the direction opposite to the arrow B, and the moderation ball 25 is moved into the recess 23 of the second moderation member 23.
b, and the operating lever 2 is temporarily held at the neutral position. Next, when the operating lever 2 is operated in the opposite direction of arrow C, the lateral groove portion 29b of the guide groove 29 of the guide member 28 is aligned with the guide pin 30 and the first pivot shaft 7 is moved. Since horizontal displacement is allowed, the first pivot 7 is displaced in the direction of arrow A, the engagement groove 17c of the first moderation member 17 engages with the moderation ball 18, and the first pivot 7 is held in a neutral position. Thereafter, when the operating lever 2 is operated in the direction of arrow D, the first pivot 7 rotates while remaining in the middle position, and the second pivot 10 is displaced in the direction of arrow D and reaches the front position. The moderation ball 25 engages with the recess 23a of the second moderation member 23, and the operating lever 2 is held at the third speed position. Then, the vehicle transmission is switched to the third speed position based on the switching states of the select and shift switches 21 and 26 in this state. To switch the vehicle transmission to the 4th gear position or the drive position, operate the operating lever 2 in the select or shift direction as appropriate in the same manner as described above, and place the operating lever 2 in the 4th gear position or the D position. The vehicle transmission is switched based on the switching states of the select and shift switches 21 and 26 corresponding to each position. At this time, the guide member 28
Of the guide grooves 29, the horizontal groove portion 29b is the guide pin 3.
0, that is, when the operating lever 2 is in the neutral position, it is of course possible to operate it in the select direction.

Also, to put the vehicle transmission into the reverse position, do as follows. That is, first, the operating lever 2 is operated in the shift direction to bring it to the neutral position, and then it is operated fully in the direction opposite to the arrow C, and then the operating lever 2 is operated in the direction opposite to the arrow D. As a result, the regulation pin 34 that has entered the regulation opening 33 comes into contact with the rear edge of the rectangular opening 33a and prevents the operation lever 2 from being operated. Operate in the opposite direction of arrow D while pushing down against the force. With this operation, the regulation pin 34 is inserted into the relief notch 33 of the regulation opening 33.
b, the operating lever 2 is displaced in the opposite direction of arrow D, and the first pivot 7 rotates accordingly, so that the locking surface portion 35 of the first moderation member 17 engages with the engagement arm 36. It comes into contact with the mating claw 36a. The engagement arm 36 has a locking member 3 at its other end.
9 is engaged and rotation in the opposite direction of the arrow E is prevented. Therefore, when the locking surface portion 35 comes into contact with the engagement pawl 36a, the rotation of the first moderation member 17 and the further rotation of the operating lever 2 are prevented. Operation is blocked. When this state is reached, the shift switch 26 switches, so the electric power is generated based on the switching state of the shift switch 26 and the switching state of the select switch 21, which has already been switched since the first pivot 7 has reached the left position. The vehicle transmission is switched to the reverse position on condition that a signal is generated and a vehicle stop detection device (not shown) detects that the vehicle is in a stopped state. and,
When the vehicle transmission is switched to the reverse position in this manner, it is detected and the solenoid 40 is energized, which causes the plunger 41 to be sucked, causing the locking member 39 to rotate in the direction of arrow F to the unlocked position. The engagement arm 36 is then unlocked. This allows the engagement arm 36 to rotate in the opposite direction of the arrow E, and in turn allows the first moderation member 17 to rotate, so the operating lever 2
can be operated to the R position. With this, the driver can confirm that the vehicle transmission has entered the reverse position, and the next operation, that is, depressing the accelerator, causes the vehicle to move backward.

As described above, according to this embodiment, by operating one operating lever 2 in each of the select and shift directions, it is possible to reliably set the operating lever 2 to any one of the six positions of 1st to 4th gears, D and R. In addition, since the operating lever 2 is pivoted by the first and second pivot shafts 7 and 10 that are displaced in directions perpendicular to each other, it is possible to reduce the size of the lever and to accommodate many speed changes. Although each axis 7,
With a simple structure in which two switches 21 and 26 for select and shift corresponding to 10 are provided, the vehicle transmission can be switched by electric signals based on the switching states of these switches 21 and 26. In particular, as in this embodiment, a guide member 28 is provided on the first pivot 7, and a guide groove 29 formed in this guide member 28 and a guide pin 30 are provided.
If the operating lever 2 can be operated in the select direction only when it is in the neutral position due to the engagement relationship with the Since it can be made almost the same as that of the device, it is convenient because it can prevent operational errors from occurring. 8 and 9 show a second embodiment of the present invention. In this case, the shift position and select position are detected by one switch 50. The switch 50 has an actuator 52, and the tip of the actuator 52 has a U-shaped notch 54.
is provided. An arm 56 is fixed to one end of the first pivot 7 with a bolt. Arm 5
6 is bent into a crank shape, and a pin 58 is attached to the other end. Pin 58 has notch 5
The actuator 52 of the switch 50 is moved in a linear direction in conjunction with the rotation of the arm 56. The pin 58 and the actuator 52 are engaged as shown in FIG. When the operating lever 2 is moved in the selection direction, the first pivot 7 moves in the left and right directions in FIG. reach the position. Next, control lever 2
When the arm 56 is moved in the shift direction, the arm 56 rotates around the central axis of the first pivot 7, and in conjunction with this, the actuator 52 moves in the direction of arrow G.

By combining the movements of the actuator 52 in the above two directions, the switch 50 can detect all combinations of positions in the select direction vs. the shift direction. The structure of the switch 50 is such that, for example, fixed contacts corresponding to the respective positions of the operating lever 2 are buried on an insulating plate, and a movable contact is provided on the actuator 52, so that the actuator moves on the insulating plate. It is conceivable that the contacts would be made conductive depending on the situation.

As described above, the present invention provides an operating lever with first and second pivots extending in the same direction, supports each of these pivots by a bearing part and a guide part, and operates the operating lever so that both pivots are orthogonal to each other. Since it is provided so that it can be operated so as to be displaced in the direction in which the control lever is moved, it has an excellent effect of being able to generate a signal corresponding to each operating position of the operating lever with a simple and compact structure.
