DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.

In FIG. 5, reference numeral 1 denotes a shift lever main body, and an operation section 3 is provided at an upper end portion. The shift lever body 1 is formed in a cylindrical shape, and the lower lever shaft 5
Are supported rotatably around the center.

The shift lever main body 1 is provided with a pin-shaped engaging body 7 protruding outward, and the engaging body 7 is provided with a push button type pressing section 9 provided on the operating section 3 and an operating rod 11.
Are connected via.

The engaging member 7 is supported by a slidable holding member 13 incorporated in the internal space of the shift lever main body 1, and has both ends in the vertical direction formed in the peripheral wall surface of the lever main body 1, 15, and one end faces a positioning groove 19 of a position plate 17 described later.

The holding member 13 is formed in a cylindrical shape, and an urging spring 21 for urging the holding member 13 upward is interposed at a lower end thereof, and a lower end of the operating rod 11 is connected to an upper end thereof. doing.

The operating rod 11 extends upward along the internal space of the shift lever body 1 and has an extended end which is
It is linked and linked. Therefore, when the pressing portion 9 is pressed with a finger (arrow in FIG. 5), a downward action is applied to the operation rod 11.

The position plate 17 is fixed to a base plate (not shown) and has a positioning groove 19.
From the left side in FIG. 5, the upper upper edge is a traveling position of first speed, second speed, D range, neutral N, reverse R, and a parking position P.

Therefore, when the engaging body 7 is lowered, a shift operation from the parking position to the traveling position or from the traveling position to the parking position becomes possible.
In both cases, switching within the travel position area during travel is
The shift operation is performed without lowering 7.

On the other hand, the shift lever body 1 has a synthetic resin rotatable second position which is rotatable between a restricting position (FIG. 6 I) and a restriction releasing position (FIG. 5II) for restricting the downward movement of the engaging member 7. 1
Is provided.

The first regulating member 23 is formed in a sleeve shape, and is provided with a window hole 25 facing the engagement body 7 and a projection 27.

The protruding portion 27 protrudes below the window hole 25, and is provided with a vertical groove 29 which allows the engagement body 7 to move downward beyond the area of the window hole 25 at the restriction release position II. Have been.

The window hole 25 has an inclined surface 25a on the upper side. The inclined surface 25a is provided when the finger is released from the pressing portion 9 when the shift is completed when the solenoid 31 is off.
The first restricting member 23 is rotated clockwise by raising the engaging body 7 by the urging spring 21 to form a tilted area where the restricting position I is set.

The lower mounting portion 2 of the first regulating member 23
A rod 33 controlled by the solenoid 31 is connected to 3a. When the solenoid 31 is off, the rod 33 is urged forward by an urging spring (not shown). Thus, when the solenoid 31 is off, the first regulating member 23 rotates counterclockwise, that is, to the regulation releasing position II, and when the engaging body 7 descends, the regulation by the engaging body 7 is released. Therefore, the first restricting member 23 rotates to the restriction releasing position II following the lowering of the engagement body 7. When the solenoid 31 is turned on, the first regulating member 23 is forcibly held at the regulating position I. Thereby, the first regulating member 23 is
Position I and restriction release position II
Can be obtained. The biasing spring in the solenoid 31 biases the engagement body 7 upward.
By setting the spring pressure weaker than the first spring pressure, when the engaging body 7 is raised by the urging spring 21, the first regulating member 23 is moved to the regulating position I by the inclined surface 25 a of the window hole 25.
Can be rotated.

The solenoid 31 is always in an off state, has a function of rotating the first regulating member 23 to the regulation releasing position II, and enables the shift operation of the shift lever body 1 to each position. . When the shift lever body 1 is in the parking position P, a key 3 to be described later
By turning on the control unit 37, a signal at the time of an operation for starting the engine from the OFF position to the start side is input to the control unit 37. The solenoid 31 that has been turned on depresses the brake pedal 39 together with a signal from the park switch 41 that detects when the shift lever body 1 has been shifted to the parking position P so that runaway such as sudden start does not occur. The signal at the time of stepping is input to the control unit 37 to be turned off.

The first regulating member 23 has an arm 43.
When the shift lever main body 1 is shifted to the parking position P (from the imaginary line to the solid line in FIG. 1), the distal end of the arm 43 is interlocked with the engagement recess 47 of the slider 45.

The slider 45 has a pair of front and rear guide pins 51 and a fixed bracket 49 supported on the vehicle body side.
51, it is slidably mounted in the range of the elongated hole 53, and is urged by an urging spring 55 in the direction of arrow B in FIG. When the engaging body 7 is lowered against the urging spring 21, the urging spring 55 is actuated via the arm 43 in addition to the operation of the rod 33 urged forward by the urging spring (not shown). Accordingly, the first regulating member 23 has an assisting function of quickly returning and rotating to the regulation release position II. The urging spring 55 is set to be weaker than the spring pressure of the urging spring 21 that raises the engaging body 7, and one end is engaged with the engaging concave portion 47 of the slider 45 and the other end is engaged with the fixed bracket 49. Have been. The slider 45 is connected via a cable 57 to a stopper member 61 constituting a second regulating member 59.

As shown in FIGS. 1 and 3, the stopper member 61 is slidably fitted in the direction of the arrow in the stopper case 63 and has a cutout groove 65. This notch groove 65
Corresponds to the opening 67 provided in the stopper case 63 so that the rotor 69 can rotate.

When the first regulating member 23 is at the regulation releasing position II, the relationship between the notch groove 65 and the opening 67 is as shown in FIG.
As shown in FIG. 2, the notch groove 65 and the opening 67 are located at a distance from each other, so that the rotation of the rotor 69 is prevented.
When the first regulating member 23 is at the regulating position I, the notch groove 65 and the opening 67 are opposed to each other, and allow the rotor 69 to rotate as shown in FIGS.

The rotor 69 is linked with a key operation by the key 35, and switches from OFF (OFF) to ACC (accessory), O
The key 35 can be rotated to N (ON) and START (start), and the key 35 can be inserted and removed at the OFF position of the key cylinder 71.

In the shift lever device of the automatic transmission configured as described above, during traveling, the shift lever body 1 is in the traveling position area, and the solenoid 31 is off. The first regulating member 23 includes the urging spring 2
The shift operation can be performed as it is in the region of D / N where the engaging body 7 does not have to be lowered, although it is at the restriction position I by the engaging body 7 by 1. Next, when the pressing portion 9 is pressed, the engagement body 7 descends. At the same time, the first regulating member 23 rotates to the regulation releasing position II following the lowering of the engagement body 7, so that the shift operation to the desired position can be performed.

Next, when the vehicle stops and gets off, the pressing portion 9 is pressed to lower the engaging body 7. At the same time, the first restricting member 23 follows the lowering of the engagement body 7 and rotates to the restriction releasing position II, so that it is further lowered to shift the shift lever main body 1 to the parking position P. At this time, the first regulating member 23 is interlocked with the slider 45 via the arm 43. A signal from the park switch 41 is input to the control unit 37. At the same time, the first regulating member 23 is turned to the regulating position I as shown in FIG. Move. The rotation of the first regulating member 23 positions the notch groove 65 of the stopper member 61 and the opening 69 via the slider 45 at a position where the opening 69 faces each other. Can be stopped. As a result, the duty of the shift lever body 1 to the parking position P can be reliably performed when getting off the vehicle.

In this case, if the user attempts to separate from the vehicle at a position other than the parking position P, the first restricting member 23 and the slider 45 are separated from each other as shown by a two-dot chain line in FIG. The member 59 disables the operation of the key 35 from the other position to the OFF position, and the engine cannot be stopped.

Next, when the vehicle travels from the parking position P, the key 35 is inserted into the key cylinder 71 and the key operation is performed from the OFF position to the start side. At this time, the solenoid 31 is turned on, and the first restricting member 23 is forcibly held at the restricting position I by the solenoid 31, so that the shift operation becomes impossible only by starting the engine, and at the same time, the shift lever main body is turned off. Since 1 is in the parking position P, there is no danger of runaway when the engine is started.

Next, after starting the engine, the brake petals 3
When step 9 is depressed, the signal at the time of stepping is input to the control section 37, and the solenoid 31 is turned off by the signal from the park switch 41 which has already been input, so that the shift conditions are made uniform. Therefore, the pressing portion 9 is pressed,
When the engaging body 7 is lowered, the first restricting member 23 comes to the restriction releasing position II following the lowering. Therefore, by further lowering the engaging body 7, the shift lever main body 1 is shifted to the traveling position. Becomes possible.

[0032]

As described above, according to the shift lever device of the present invention, as described above, the first restricting member which rotates to the restricting position by the lifting of the engaging body, the first restricting member,
Since the solenoid for rotating the regulating member to the regulation releasing position is provided, the occupied space can be reduced, and the size can be reduced. Also, if the shift lever body is not shifted to the parking position when getting off the car, the engine cannot be stopped and the key cannot be pulled out, so that it is possible to ensure the obligation to go to the parking position when getting off . Therefore, the engine is always started at the parking position when the engine is started, so that runaway when the engine is started can be prevented. Further, when the vehicle runs after the engine is started, the shift operation to the driving position cannot be performed unless the brake pedal is depressed, so that sudden start and the like can be prevented.
