Effect As described with reference to FIG. 3, in the vehicle shifter device 1 according to the present embodiment, the first path (arrow A _{1) along} which the shift lever 10 moves when the shift range is switched between the P range and the R range. And a second route different from the first route (routes indicated by arrows A ₄ and A ₅ ) when switching the shift range from the N range and the D range to the P range. 10 is configured to move. Therefore, in the vehicle shifter device 1 according to the present embodiment, when the shift range is switched from the N range and the D range to the P range, the shift lever 10 is moved to the P position 10p without passing through the R position 10r. It can be moved directly and can be shifted to the P range with a simple operation.

  Further, in the vehicle shifter device 1, each shift range of the P range, the R range, the N range, and the D range can be switched only by operating the shift lever 10. In addition, it is not necessary to perform different operations (operations with the shift lever and operations with the push button switch) depending on the shift range, and the driver's erroneous operation during shift shifting can be suppressed.

  Therefore, in the vehicle shifter device 1 according to the present embodiment, it is possible to directly shift from the respective ranges of the N range and the D range to the P range with a simple operation, and to suppress erroneous operations by the driver. it can.

In the section in which the shift lever 10 moves to the position 10p, the detent guide 26 is formed with the inclined groove portion 26g. Therefore, due to the elastic force acting to project the detent plunger 22 toward the groove bottom of the detent guide 26, The shift lever 10 automatically moves to the P position 10p. Therefore, the driver simply moves the shift lever 10 to the relay position 10v ₁ or relay position 10v _2, then, the shift lever 10 is automatically moved to the P position 10p. Therefore, the driver's shift operation can be simplified, which is effective in suppressing erroneous operations.

It should be noted that the P range is desirable when the driver moves the shift lever 10 to the relay position 10v ₁ or the relay position 10v ₂ from the viewpoint of ensuring high responsiveness to the driver's shift operation.

  In addition, since the vehicle shifter device 1 according to the present embodiment includes the detent mechanism (detent case 21 and detent plunger 22) and the detent guide 26, recognition when the driver selects each shift range. Can also be obtained from information from the hand holding the shift lever 10 (information by reaction force or the like).
