Abstract

A shift device is configured including a restriction member and a release section. The restriction member stops a detent pin that has been moved at a release position, restricting movement of a shift lever to a third shift position when the shift lever is moved from a first shift position to a second shift position. When the shift lever has been moved at the second shift position, by the detent pin being moved to the release position from a non-release position, the release section releases the restriction of movement of the shift lever toward the third shift position by the restriction member.

First claim

What is claimed is:

1. A shift device comprising:
a housing;
a shift member that is provided at the housing so as to be rotatable in a first rotation direction and in a second rotation direction so as to be movable from a first shift position to a third shift position through a second shift position;
a detent section that is provided at the housing, and that includes a first detent portion and a second detent portion;
a detent pin that is provided at the shift member such that the detent pin is arranged inside the detent section, and that is movable relative to the shift member between a non-release position and a release position on the shift member, movement of the shift member from the first shift position to the second shift position being enabled by the detent pin being positioned at the release position;
a restriction and release section that is movably mounted on the housing and that includes an engagement surface, the restriction and release section being movable relative to the housing in a first direction to a first position and in a second direction which is different from the first direction to a second position;
wherein when the detent pin is positioned at the release position, and the shift member is rotated from the first shift position toward the third shift position, the detent pin engages the engagement surface and moves the restriction and release section in the first direction to the first position, which restricts further rotational movement of the shift member beyond the second shift position, and
wherein when the detent pin is positioned at the non-release position and the shift member is at the second shift position, the detent pin disengages the engagement surface and restriction of further rotational movement of the shift member beyond the second shift position by the restriction and release section is released due to the restriction and release section moving in the second direction to the second position, such that the shift member is free to rotate into the third shift position when the detent pin is subsequently positioned into the release position.

2. The shift device of claim 1 , wherein the restriction and release section includes:
a movable member that is moved by the detent pin which has been moved at the release position when the shift member is moved from the first shift position to the second shift position, and whose movement by the detent pin is canceled by movement of the detent pin to the release position being canceled when the shift member has been moved at the second shift position; and
a movement section that, when the shift member has been moved at the second shift position, moves the restriction and release section via the movable member by the detent pin being moved from the non-release position toward the release position, to release the restriction of movement of the shift member toward the third shift position.

3. The shift device of claim 2 , wherein: the movable member is capable of moving with respect to the restriction member in a movement direction of the detent pin when the detent pin is moved accompanied by movement of the shift member from the first shift position toward the second shift position; and the movable member is restricted from moving with respect to the restriction member in a movement direction of the detent pin when the detent pin is moved toward the release position from the non-release position.

4. The shift device of claim 3 , wherein the movement section is configured so as to turn the restriction member.

5. The shift device of claim 3 , wherein the movement section is configured so as to slide the restriction member.

6. The shift device of claim 2 , wherein the movement section is configured so as to turn the restriction and release section.

7. The shift device of claim 2 , wherein the movement section is configured so as to slide the restriction member.

8. The shift device of claim 1 , wherein the restriction and release section includes a resilient member, wherein:
when the shift member has been moved at the second shift position, the resilient member moves the restriction and release section to a movement start position at which releasing of the restriction of movement of the shift member toward the third shift position by the restriction and release section is started when movement of the detent pin to the release position is canceled; and
when the shift member has been moved at the second shift position, the detent pin moves, against urging force of the resilient member, the restriction and release section from the movement start position to release the restriction of movement of the shift member toward the third shift position by the restriction and release section, by the detent pin being moved from the non-release position toward the release position.

9. The shift device of claim 1 , wherein the restriction and release section is urged in the second direction by an urging member.

10. The shift device of claim 1 , wherein
the restriction and release section includes a second engagement surface that is different from the engagement surface recited in claim 1 , and when the detent pin is positioned at the non-release position and the shift member is at the second shift position, the restriction and release section is moved in the second direction to the second position by the detent pin engaging and pressing the second engagement surface due to the detent pin moving from the non-release position to the release position.

11. The shift device of claim 10 , further comprising a restricting portion which is provided at the housing, wherein when the detent pin is positioned at the release position, and the shift member is rotated from the first shift position toward the third shift position, the detent pin engages the engagement surface and moves the restriction and release section in the first direction to the first position, which restricts the further rotational movement of the shift member beyond the second shift position by the restriction and release section being abutted and stopped by the restricting portion.

12. The shift device of claim 1 , further comprising a restricting portion which is provided at the housing, wherein when the detent pin is positioned at the release position, and the shift member is rotated from the first shift position toward the third shift position, the detent pin engages the engagement surface and moves the restriction and release section in the first direction to the first position, which restricts the further rotational movement of the shift member beyond the second shift position by the restriction and release section being abutted and stopped by the restricting portion.
