1 to 3 show a preferred embodiment according to the present invention. FIG. 1 is a side view of a shift lever device, and FIG. 2 is a side view of a shift lever 3 having a seesaw portion 5. FIG. 3 is a cross-sectional view taken along line AA of FIG. 2.

In the figure, 31 is a push button, 32 is a detent pin, 3 is a shift lever, 4 is a detent plate, 5 is a seesaw portion, 6 is a display panel showing each shift range, 7 is a stopper, and 8 is a solenoid. These are described in detail below.

[0008] First pushbutton 31 is configured to operate when the driver of the vehicle switches the shift position. The push button 31 is mechanically connected to a detent pin 32 via a cam mechanism (not shown).
Is operated, the detent pin 32 operates against the elastic force of the spring 34. The push button 31, the detent pin 32 and the spring 3
4 is provided on the shift lever 3.

The detent plate 4 has a stepped portion corresponding to each shift operation position such as a P (parking) range, an R (reverse) range, an N (neutral) range, a D (drive) range, a 2 range or a 1 range. 41. The detent plate 4 is
With other configurations of the shift lever device is molded by synthetic resin, the detent plate 4 of the stepped portion 41 of generally at the outer region angle the detent from swinging area angle θ of the shift lever 3 as shown in FIG. 1 It is provided at the portion of the plate 4 .

The seesaw portion 5 has a support shaft 53 fitted and mounted on the base 33 of the shift lever 3, and is rotatable clockwise and counterclockwise about the support shaft 53. The seesaw portion 5 has a slit 51 that engages with the detent pin 32 and an engagement pin 52 that engages with the step portion 41.
To the detent pin 32 and the engagement pin 52 at the other end.
Are respectively engaged with the step portions 41 of the detent plate 4.

The shift lever device has a stopper 7 and a solenoid 8 as indicated by phantom lines in FIG. The stopper 7 has a function of restricting the movement of the detent pin 32 at a position indicated by a virtual line a in FIG. 1 until the brake (not shown) is operated when an ignition key (not shown) is turned on. Have.

The solenoid 8 has the function of exciting the brake 7 when the ignition key is turned on to move the stopper 7 to the position indicated by the imaginary line b in FIG. Thus, the restriction state of the detent pin 32 by the stopper 7 is released. If the solenoid 8 becomes inoperable for some reason, the display panel 6
It is also possible to insert a key or the like from a hole (not shown) provided in the above and manually move the stopper 7 to the position indicated by the imaginary line b.

The embodiment thus constructed operates as follows. That is, when the driver operates the shift lever 1 and operates the push button 31 to switch to any of P, R, N, D, 2 or 1 range, the operation of the push button 31 causes the detent pin 32 to move as shown in FIG. It operates in the downward direction shown in FIG. However, when the push button 31 is in the P range and the stopper 7 is at the position of the imaginary line a shown in FIG. 1, the detent pin 32 is regulated by the stopper 7 and the detent pin 32 is inoperable. It has become.

When the detent pin 32 operates downward, the operating force is transmitted to the seesaw section 5 through the slit 51. Thus, the seesaw portion 5 rotates counterclockwise about the support shaft 53, and the engagement pin 52 also rotates counterclockwise. Then, the engagement pin 52 is disengaged from the step portion 41, and the shift lever 3 can freely move at the swing area angle θ. For example, it is possible to switch from the P range indicated by the solid line in FIG. 1 to another range.

When the operation of the push button 31 is stopped after the shift lever 3 has been selected to the desired range, the engaging pin 52 of the seesaw portion 5 engages with the corresponding step portion 41, and the shift lever 3 is moved. Hold in that range.

[0016]

[Other Embodiments] In addition, the present invention only needs to have a structure in which a shift lever is provided with, for example, a seesaw portion having one end engaged with a detent pin and the other end engaged with a step portion of a detent plate. Various modifications are possible without being limited to the above embodiment.

[0017]

Since the present invention has the above-described construction, the following effects can be obtained. That is, the seesaw section is clockwise
And the counterclockwise rotation, so that the engagement pin
The shift lever is at the swing range angle θ.
Can be moved freely. Also, the step is the shift lever
Detent play in the range of the outside area angle of the swing area angle
The height of the detent plate is extremely
Umate can be low, for example, even when molding the detent plate of a synthetic resin, not a large shape in order to ensure the desired strength.
