BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever device provided with lever guide means for guiding a shift lever in a predetermined shift operation direction.

[0002]

2. Description of the Related Art A conventional example of this type of shift lever device will be described with reference to FIGS. FIG. 5 is a partially broken side view showing a main part of the shift lever device. In FIG. 5, a bracket 110 is fixed on a vehicle body floor (not shown) of a vehicle. The shift lever 1 is attached to the bracket 110.
20 is supported so as to be shiftable as described below. The shift lever 120 has a lever shaft 121 and a lever holder 122. The lever shaft 121
The shift knob 123 is attached to the upper end portion 121a of the camera.

The shift shaft 13 is attached to the bracket 110.
0 is supported rotatably about its axis. The shift shaft 130 includes a lever holder 122 of the shift lever 120.
Is rotatably supported via a select shaft 132 orthogonal to the shift shaft 130. Therefore, the shift lever 120 moves the shift shaft 13 with respect to the bracket 110.
It is supported so as to be operable in a combined direction of the zero axis direction and the select axis 132 axis direction. This allows
The shift knob 123 of the shift lever 120 includes a front-rear direction (left-right direction in FIG. 5, this direction is referred to as a “shift direction”) of a vehicle body (not shown), and a direction orthogonal to the shift direction (in FIG. This direction is referred to as a “selection direction”).

[0004] As shown in FIG.
On the top, a gate portion 114 as a lever guide means for guiding the shift lever 120 in a predetermined shift operation direction.
Is provided. The gate portion 114 has a substantially rectangular plate shape, and is formed in an arc shape having a radius B centered on the axis 130L of the shift shaft 130. The gate portion 114 includes the lever shaft 12 of the shift lever 120.
The guide groove 114a with which 1 engages by penetration is formed. As shown in a plan view in FIG. 6, the guide groove 114a is formed in a pattern shape corresponding to a predetermined shift operation of the lever shaft 121 of the shift lever 120 (see FIG. 5). The guide groove 114a is provided on the lever shaft 121.
By restricting the moving direction of the shift lever 120,
(See FIG. 5) is guided in a predetermined shift operation direction.

[0005]

In the above-mentioned conventional shift lever device, the lever shaft 121 of the shift lever 120 is used.
Requires a certain diameter φD (see FIG. 5) due to strength restrictions. Note that the diameter φD is referred to as a lever diameter φD in this specification. Further, the moving direction of the shift lever 120 is regulated by the guide groove 114a of the gate portion 114. Therefore, the groove width D of the guide groove 114a (see FIG. 6).
Is determined based on the lever diameter φD (see FIG. 5).
The gate portion 114 has a weakest portion 114b (see a partial plan view in FIG. 7) that projects sharply into the guide groove 114a by setting the guide groove 114a (see FIG. 6).

Therefore, if the size of the conventional shift lever device is to be reduced, the radius B (see FIG. 5) of the gate portion 114 is set to a small size, and
It is conceivable to reduce the length L in the front-back direction of 14.
Then, the area of the gate portion 114 protruding from the weakest portion 114b (see FIG. 7) becomes small, and the gate portion 1
14 may not be established in terms of strength. For this reason,
The radius B (see FIG. 5) of the gate portion 114, which determines the size of the shift lever device, is substantially determined mainly by the lever diameter φD of the shift lever 120 (see FIG. 5). There was a limit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. In the present embodiment, a floor shift lever device as a representative example of the shift lever device will be described.
FIG. 1 is a partially broken side view showing a main part of a shift lever device,
FIG. 2 is a partially cutaway front view. 1 and 2, the bracket 10 is fixed on a vehicle body floor (not shown) of the vehicle. The bracket 10 has a left side plate 11 (see FIG. 2) and a right side plate 12 which are parallel to each other. A shift lever 20 is supported by the bracket 10 so as to be shiftable as described below. Also,
The shift lever 20 is an integrally molded product having a lever holder 22 obtained by resin-molding a metal lever shaft 21 so-called insert molding. As shown in FIG. 1, a shift knob 23 is attached to the upper end 21a of the lever shaft 21. The portion of the lever shaft 21 other than the upper end 21a to which the shift knob 23 is attached is formed in a round bar shape or a hollow cylindrical shape having a diameter (also referred to as a lever diameter) φD.

As shown in FIG. 2, a shift shaft 30 is provided between the left side plate 11 and the right side plate 12 of the bracket 10.
Is supported so as to be rotatable around its axis in a state of being installed. The shift shaft 30 is provided with a lever holder 22 of the shift lever 20 and a select shaft 3 orthogonal to the shift shaft 30.
2 so as to be rotatable. Therefore, the shift lever 20 is connected to the shift shaft 30 with respect to the bracket 10.
And the select shaft 32 is operably supported in a combined direction. As a result, the shift knob 23 of the shift lever 20 can be moved in the front-rear direction (corresponding to the left-right direction in FIG. 1 and the direction is referred to as the “shift direction”) of the vehicle body (not shown) and the direction orthogonal to the shift direction (FIG. 1 corresponds to the front and back sides of the paper surface, and the direction is referred to as a “selection direction”).

The shift lever device is provided with lever guide means for guiding the shift lever 20 in a predetermined shift operation direction. The lever guide has a guide pin 14 and a gate 24.

As shown in FIG. 2, the guide pins 14
Is attached to a pin support 12a integrally formed on the upper end of the right side plate 12 of the bracket 10. A substantially upper half of the guide pin 14 protrudes from the pin support 12a. The guide pin 14 is formed in a round bar shape or a hollow cylindrical shape having a diameter (also referred to as a pin diameter) φd over the entire length thereof. Note that the bracket 10 corresponds to a fixed-side member in this specification, and the guide pin 14 corresponds to a guide pin portion in this specification.

As shown in FIG. 2, the gate portion 24 comprises:
The shift lever 20 is formed integrally with the upper end of the lever holder 22. Further, the gate portion 24 is provided with the lever holder 2.
2 protrudes rightward (to the right in FIG. 2). The gate portion 24 has a substantially rectangular plate shape,
The shift shaft 30 is formed in an arc shape with a radius b (see FIG. 1) centered on the axis 30L. As shown in FIG. 1, the gate portion 24 is formed with a guide groove 24a through which the upper end of the guide pin 14 is engaged. The guide groove 24a is formed in a pattern corresponding to a predetermined shift operation of the shift lever 20 (see FIGS. 1 and 2) (see a plan view in FIG. 3). The guide groove 24a guides the shift lever 20 in a predetermined shift operation direction by relatively restricting the movement direction of the guide pin 14. As is well known, a transmission (not shown) of the vehicle is shifted in response to a predetermined shift operation of the shift lever 20.

In the above-mentioned shift lever device, the guide pin 14 and the gate portion 2 of the lever guide means which are separately arranged on the bracket 10 and the shift lever 20 and engage with each other.
4 are relatively moved based on the shift operation of the shift lever 20, whereby the shift lever 20 is guided in a predetermined shift operation direction.

In order to reduce the size of the shift lever device, the shift lever 20 (specifically, the lever shaft 21) is used.
Of the lever diameter φD of the guide pin 14
The relationship of φD> φd is satisfied (see FIG. 2). The pin diameter φd of the guide pin 14 is set to, for example, a minimum necessary diameter. Diameter φD of lever shaft 21 of shift lever 20
Is set to a diameter determined by strength constraints.

The moving direction of the guide pin 14 is regulated by the guide groove 24a of the gate portion 24. For this reason,
The groove width d of the guide groove 24a (see FIG. 3) is
4 (see FIG. 2). Also,
As shown in FIG. 3, a guide groove 24a is formed in the gate portion 24.
The weakest portion 24b that projects sharply is formed in the guide groove 24a. Therefore, the radius b (see FIG. 1) of the gate portion 24 can be set to be as small as about φd / φD as compared with the conventional shift lever device (see FIG. 5).

As described above, since the radius b of the gate portion 24 is reduced, the length La of the gate portion 24 in the front-rear direction (left-right direction in FIG. 1) can also be reduced. Thereby, the gate portion 24 can be easily formed integrally with the shift lever 20 (specifically, the lever holder 22). In addition, by forming the gate portion 24 integrally with the shift lever 20, the size of the bracket 10 can be reduced. That is, in the conventional example (see FIG. 5), the bracket 10
Is for holding the gate portion 24, so the bracket 10 having a size capable of holding the gate portion 24 is required. However, according to the present embodiment, as shown in FIG. 2, only the support of the shift shaft 30 and the guide pin 14 is sufficient, so that the size of the bracket 10 can be reduced.

According to the shift lever device configured as described above, the gate portion 24 of the lever guide means is different from the conventional example in which the shift lever 20 itself is guided (see FIG. 5).
The guide pin 14 which is not affected by the lever diameter φD of the shift lever 20 is guided (see FIG. 2). For this reason, miniaturization can be easily realized. That is, the lever diameter φD of the shift lever 20 and the pin diameter φd of the guide pin portion 14
However, by setting the dimensions so as to satisfy the relationship of φD> φd, the outer shape of the gate portion 24 to which the guide pin 14 is engaged and whose size is determined by the pin diameter φd of the guide pin 14 is set to the shift lever 20 itself. Since the pin diameter φd is smaller than the lever diameter φD, the outer shape of the gate portion 24 can be made smaller than the outer shape of the gate portion 114 (see FIG. 5) of the conventional example (see FIG. 2).

The guide pin 14 is connected to the bracket 10
In addition, it is possible to provide a shift lever device in which the gate portions 24 are respectively provided on the shift levers 20.

Further, since the gate portion 24 is formed integrally with the shift lever 20, the number of steps for assembling the gate portion 24 can be reduced.

The present invention is not limited to the above embodiment, but can be modified without departing from the scope of the present invention. For example, the present invention is not limited to the floor shift lever device, and can be applied to other shift lever devices, for example, a column shift lever device, an instrument panel shift lever device, and the like. The fixed member is not limited to the bracket 10, but may be any member fixed to the vehicle body. Further, instead of the guide pins 14, a pin-shaped guide pin portion corresponding to the guide pins 14 may be formed integrally with the bracket 10. The gate portion 24 can also be formed by attaching a gate member having a guide groove 24a to the shift lever 20. Further, the lever holder 22 of the shift lever 20 can be formed by casting instead of resin molding.

Further, as shown in a partially cutaway side view in FIG. 4, the gate portion 24 in the shift lever device of the above embodiment may be formed integrally with the lower end portion of the lever holder 22 of the shift lever 20. In this case, the arrangement of the pin support 12a and the guide pins 14 is also changed in accordance with the change in the arrangement of the gate 24.

In the above embodiment, the lever diameter φD of the shift lever 20 and the pin diameter φd of the guide pin 14 satisfy the relation of φD> φd, but may be set to the relation of φD ≦ φd. . Further, in the above embodiment, the gate portion 24 is formed integrally with the shift lever 20, but the gate portion 24 formed separately from the shift lever 20 may be assembled to the shift lever 20. In addition, the guide pin 14 and the shift lever 20 can be formed with a modified cross section other than a circular or hollow circular shape. Further, the guide pin 14 and the shift lever 20 need not have the same diameter or the same cross section over the entire length.

[0029]

According to the shift lever device of the present invention, the gate portion of the lever guide means guides the guide pin portion which is not influenced by the lever diameter φD of the shift lever, unlike the conventional example which guides the shift lever itself. Thereby, miniaturization can be easily realized.
