SUMMARY OF THE INVENTION In consideration of the above facts, the present invention has a simple structure while ensuring further safety,
An object of the present invention is to provide a shift lever device that can be surely brought into a shift lock state under specific conditions.

[0006]

SUMMARY OF THE INVENTION A shift lever device of the present invention includes a shift lever mounted on a shaft support member having a base end portion supported axially so as to be relatively movable, and a shift lever device protruding at a predetermined position of the shift lever. The detent pin that is provided, the detent member that is arranged in correspondence with the predetermined shift range position of the shift lever, and the shift range position that prevents continuous shift operation of the shift lever are abutted by the detent pin and move further continuously. The shift end is formed on one side of the detent member and the shift lever is moved relative to the shaft support member so that the detent pin has passed over the stop end face. A guide surface formed on a part of the detent member so as to slidably support the detent pin in accordance with the switching operation.

With the above-described structure, when the shift lever is shifted, the detent pin stops the detent member when the shift lever reaches a predetermined shift range position where the shift lever is continuously stopped during a shift operation. It hits the end face and further continuous movement is stopped. At this time, if the shift lever is moved relative to the shaft support member to cross over the stop end face, the switching operation to the next shift range is continued. In this state, the detent pin slides on the guide surface of the detent member and maintains the position of the shift lever after the relative movement with respect to the shaft support member.

Further, when the shift lever switching operation is performed in the opposite direction to the above-described operation, the detent pin slides on the guide surface and the shift lever moves relative to the shaft support member when passing through the stop end surface. It becomes possible to move to return to and continue the switching operation.

At the same time, the shift lock arm member 34 rotates about the shaft pin 70, so that the catch portion 42 is guided by the guide hole 30 as shown in FIG.
It is configured to be able to move to a parking shift lock position which is located on the right side of FIG.

The shift lever 12 has a guide hole 30.
In the state of FIG. 2 which has reached the P shift range position inside,
The shift lever 12 is fitted in the recess 48 of the catch portion 42, and the detent pin 20 of the shift lever block 14 is attached.
Is configured so that its free end rides on the detent member 80.

The detent member 80 is the shift lever 1
2 constitutes a part of a detent mechanism for preventing erroneous operation of 2 from the neutral (N) shift position to the reverse (R) shift position.

As shown in FIGS. 1 to 4, the detent member 80 is formed by forming a guide surface 82 having an arcuate side surface on the upper portion of a rectangular member. The guide surface 82 is composed of a flat guide surface portion 82A having a cylindrical peripheral surface shape and an inclined guide surface portion 82B having a conical peripheral surface shape. The inclined guide surface portion 82B is, as shown in the drawing,
The shift lever block 14 is configured to incline downward from a high position in the drawing toward the flat guide surface portion 82A.

The detent member 80 is fastened to a structural member (not shown) with a screw or the like and is arranged at a predetermined position. In this arranged state, the arc of the guide surface 82 forms one of the circumferences around the axis of the shaft 26. It is configured to form a part.

Further, the end surface of the detent member 80, which has a high height and corresponds to the end surface on the right side in FIG. 3, is arranged and configured as a stopping end surface portion 84 of the detent pin 20.

That is, the stop end surface portion 84 is such that the shift lever 12 is at the neutral (N) shift position in FIG.
When the shift lever 12 is pushed down by the coil spring 18 to the bottom position in the block 14, the detent pin 20 comes into contact with the shift lever 12 in the reverse (R) shift position direction, that is, in the direction of arrow B in FIG. It is configured to stop rocking.

Then, by pulling up the shift lever 12 in the N shift position to release the detent pin 20 from the stop end surface portion 84, the shift lever 12 is moved to the position shown in FIG.

Next, the operation and operation of the shift lever device according to the present embodiment configured as described above will be described.

In the shift lever device according to the present embodiment, the shift interlock operation is restricted when the shift lever 12 is in the parking (P) shift position, and the shift lever 12 is reverse (R) from the neutral (N) shift position. A so-called R inhibit operation restriction is imposed to prevent unconditional movement to the shift position.

First, the shift interlock at the parking P shift position will be described. When the driver operates the shift lever 12 to the P shift position as shown in FIG. 2, the shift lever 12 shifts the shift lock mechanism 32. Is caught by the catch portion 42 of. When the shift lever 12 is laterally moved rightward in FIG. 2 in this state, the shift is locked. That is, by this movement operation, the shift lock arm member 34 is rotated in the direction opposite to the arrow A against the biasing force of the spring 74 in cooperation with the shift lever 12, and the shift lock state shown in FIG. 1 is obtained.
Further, along with this operation, the cable core member 78 is operated in a direction to be drawn into the cable member 76, and the detent pin 20 is operated against the biasing force of the spring 18 to climb the inclined guide surface portion 82B.

In the shift interlock state at the parking P shift position shown in FIG. 1, the mechanical shift lock device 86 connected to the cable member 76 is interlocked with the lock pin 96 to engage with the first locking portion 92 and the cable is locked. The movement of the core material 78 is prevented. That is, since the rotation of the shift lock arm member 34 is blocked, the shift lock state is set in which the shift lever 12 is blocked from moving in another shift range (so-called P range shift lock). This P
The range shift lock state is released when the driver depresses the brake pedal while turning the key.
That is, when the brake pedal is depressed, the mechanical shift lock device is interlocked and the lock pin 96 is locked by the first locking portion 9.

4 can rotate in the direction of arrow A while pulling out the cable core member 78 in conjunction with the shift lever 12 to shift to the shift lock release state shown in FIG. 2, and to a shift range other than the P shift range of the shift lever 12. Shift lock is released so that the shift can be made. The operation of moving the shift lever 12 laterally makes it easy for the driver to apply an operation force, which improves operability.

The shift lever 12 in the released state of the shift lock has R, N, D, 2,
Or, it can be moved to the L range position.

Next, the R inhibit of the shift lever device will be described. The shift lever 1 is operated by the driver.
When 2 is moved to the neutral (N) shift position, the detent pin 20 moves the guide surface 82 of the detent member 80.
, And the state shown by the chain double-dashed line corresponding to the N shift position in FIG. 3 is reached. In this state, even if the shift lever 12 is attempted to move from the N shift position to the R shift position direction (to the left in FIG. 3), the detent pin 20 has the blocking end surface portion of the detent member 80 on the left side in the figure. It hits 84 and prevents its operation.

When the blocking action of the detent pin 20 is released, the shift lever 12 is moved to the spring 18
R in the state of being pulled up in the axial direction against the urging force of
When the detent pin 20 is swung to the shift position and the shift lever 12 is released, the detent pin 20 goes over the stop end surface portion 84 and rides on the guide surface 82, so that a shift change operation can be performed. In this way, the shift change operation can be performed only by pulling up the shift lever 12, and further safety can be secured.

When the shift lever 12 is moved from the N shift position toward the D, 2 or L shift position, the detent pin 20 is not restricted at all.
The shift lever 12 can be freely changed to the N, D, 2 or L shift position.

As described above, in the shift lever device according to the present embodiment, the shift lock arm member 34, the holder member 36, and the like are operated to shift lock the shift lever 12 at the parking (P) shift position or release the shift lock operation. The shift lock mechanism 32 has a simple and strong structure and can be executed. In addition, an R inhibit that prevents unconditional movement of the shift lever 12 from the neutral (N) shift position to the reverse (R) shift position is provided to the shift lever 1.
In addition to the above, the detent pin 20 and the detent member 80, which can be pulled up, can be used for the simple configuration. Therefore, the entire structure of the shift lever device can be simplified, downsizing can be provided, an inexpensive product can be provided, further safety can be ensured, and the shift lock state can be reliably achieved under a specific condition. .

Although the shift lock arm member 34 is configured to be rotatable by pivotally supporting the shift lock arm member 34 with the shaft pin 70 in the above-described embodiment, the present invention is not limited to this structure. Instead, the shift lock arm member 34 is interlocked with the mechanical shift lock device from the parking shift lock release position corresponding to the P shift range position of the guide hole 30 to the parking shift lock position, in addition to linear movement such as slide movement, It may be configured to perform various movement operations. Further, in the above-described present embodiment, the shift lever 12 is movable in the axial direction with respect to the block 14. However, the present invention is not limited to this structure, as long as the detent pin 20 integrated with the shift lever 12 can move onto the guide surface 82 beyond the stop end surface portion of the detent member 80. The detent pin 20 may be configured to cross the stop end surface portion of the detent member 80 by pressing the shift lever 12, obliquely pulling it, or rotating it. Further, the detent pin 20 may be configured to be movable without being fixed to the shift lever 12.
