## Abstract

In a shift device, when a lock lever is disposed at a restriction position or an intermediate position, a detent groove of a lever is abutted by the lock lever, and pivoting of the lever from a D position toward an S position, and pivoting of the lever from the S position toward the D position, is restricted. However, when the lever is disposed at the D position or the S position, by moving the lock lever to a permitted position, the detent groove does not abut the lock lever and so pivoting of the lever from the D position toward the S position and pivoting of the lever from the S position toward the D position is permitted. Thus, pivoting of the lever from the D position toward the S position and pivoting of the lever from the S position toward the D position can be restricted and permitted.

## Claims

### Claim 1

A shift device comprising:
a shift body that is moved to change a shift position, a second shift position being disposed immediately next to a first shift position, an N position being disposed immediately next to the first shift position or the second shift position; and
a restriction section that is operable from a first position to a second position and from the second position to a third position, that is operated from the first position to the second position upon a predetermined condition being met and upon the shift body having been disposed at the N position, movement of the shift body from the N position to an R position and from the R position to a P position is unimpeded by the restriction section when the restriction section is disposed at the second position, the movement of the shift body between the first shift position and the second shift position is restricted when the restriction section is disposed at the second position, and, that is disposed at the third position upon the predetermined condition being met and upon the shift body having been disposed at the first shift position or the second shift position, so as to permit movement of the shift body between the first shift position and the second shift position; wherein
the N position corresponds to a neutral shift position of a vehicle, the R position corresponds to a reverse shift position of the vehicle, and the P position corresponds to a park shift position of the vehicle.

### Claim 2 (depends on 1)

The shift device of claim 1, wherein the predetermined condition is operation of an operation section provided at the shift body.
