At the upper end of the lever 18, a knob 18A (see FIGS. 3 and 4) serving as an operating unit is fixed. The knob 18A is grippable by a vehicle occupant (in particular, a driver), and is operated in the front-rear direction in a state where the knob 18A is gripped by the occupant, and the lever 18 is slid in the front-rear direction. The lever 18 is slid back and forth so that the shift position can be changed. The shift position of the lever 18 is, for example, “R” position (reverse position), “N”, from the front side to the rear side. The position (neutral position), the "H" position (home position), the "N" position (neutral position) and the "D" position (drive position) are changed.

In the biasing box 12A in the plate 12, a substantially rectangular columnar check pin 22 (detent pin, see FIG. 6) as a moderating member constituting the biasing mechanism of the moderating mechanism is coaxially fitted with the biasing box 12A.

It is arranged perpendicular to. The sensor substrate 28 is capable of detecting the magnetic field generated by the magnet 26. When the sensor substrate 28 detects the sliding position of the magnet 26 in the front-rear direction, the sliding position of the lever 18 in the front-rear direction is detected. Thus, the shift position of the lever 18 is detected.

In the plate 12, a substantially rectangular box-shaped sensor housing 30 (see FIG. 3) as a covering member constituting a support is fixed on the lower side of the sensor substrate 28, and the inside of the sensor housing 30 is the upper side. It is open to you. A sensor substrate 28 is accommodated in the sensor housing 30, and the sensor housing 30 covers the sensor substrate 28 from the lower side.

Next, the operation of the present embodiment will be described.

In the shift device 10 configured as described above, the slide portion 20A of the guide portion 20 of the lever 18 is supported by the slide plate 16 of the plate 12. By operating the knob 18A of the lever 18 in the longitudinal direction, the lever 18 is slid in the longitudinal direction while the slide portion 20A is slid in the longitudinal direction along the slide plate 16, and the shift position of the lever 18 is changed. Ru. Furthermore, when the sensor substrate 28 detects the sliding position of the lever 18 in the front-rear direction of the magnet 26, the sliding position of the lever 18 in the front-rear direction is detected. Further, the check pin 22 of the plate 12 is brought into contact with the detent surface 20D of the check portion 20C of the guide portion 20 of the lever 18 by the urging force of the check spring 24, whereby the lever 18 is urged toward the "H" position. .

Here, not only the slide portion 20A but also the check portion 20C (moderate surface 20D) is provided in the guide portion 20 of the lever 18, and the positions of the slide portion 20A and the moderation surface 20D are approached (in particular, the slide portion 20A and The vertical position with the moderation surface 20D is substantially matched). For this reason, when the lever 18 is disposed at a position other than the “H” position, the tilting torque in the vertical direction of the slide portion 20A due to the biasing force of the check spring 24 with respect to the moderation surface 20D can be reduced. Thereby, when the lever 18 is slid in the front-rear direction, the tilting power in the vertical direction of the slide portion 20A with respect to the slide plate 16 can be reduced, and the slide resistance in the front-rear direction of the slide portion 20A with respect to the slide plate 16 The sliding performance of the lever 18 in the front-rear direction can be improved. Moreover, for example, even when the shift device 10 is provided with a drive mechanism (not shown) and the lever 18 is slid to the specific shift position by the drive force of the drive mechanism, the sliding performance of the lever 18 by the drive mechanism can be improved.

Furthermore, a pair of sliding portions 20B are formed to project on the upper and lower surfaces of the sliding portion 20A of the lever 18 and on both left and right outer side surfaces in the front and rear direction, and the lever 18 is slid in the front and rear direction. The slide portions 20B of the pair of slide portions 20A of the lever 18 slide in the front-rear direction with respect to the upper surface, the lower surface, and the left and right direction inner side surface of the pair of slide plates 16, respectively. Therefore, when the lever 18 is slid in the longitudinal direction, rattling of the pair of slide portions 20A in the vertical direction and the lateral direction with respect to the pair of slide plates 16 can be suppressed, and the lever 18 is in the vertical direction and the lateral direction It is possible to suppress backlash.

Further, the guide portion 20 of the lever 18 is projected outward in the left-right direction (slide width direction side) of the lever 18, and on the lower side of the check portion 20C of the guide portion 20 (slide vertical direction side of the lever 18) Is provided. Therefore, the shift device 10 can be miniaturized in the left-right direction as compared with the aspect in which the check pin 22 and the check spring 24 are disposed on the outer side in the left-right direction of the lever 18 of the guide portion 20.

Further, a moderation surface 20D, a check pin 22 and a check spring 24 are provided on both sides in the left-right direction of the lever 18 and on the lower surface of the check portion. For this reason, even if the urging force of each check spring 24 is reduced, the urging force to the lever 18 can be secured, and the axial dimension (vertical dimension) of each check spring 24 can be reduced. It can be miniaturized.

A magnet 26 is provided at the lower end of the lever 18. For this reason, unlike the case where the magnet 26 is provided on the interlocking member interlocked with the sliding of the lever 18 in the front-rear direction, the accuracy of the position of the magnet 26 with respect to the sliding position of the lever 18 in the front-rear direction can be increased. The detection accuracy by the sensor substrate 28 of the slide position in the front-rear direction of the sensor can be improved. Moreover, the need to provide the interlocking member can be eliminated, and the number of parts can be reduced.

Furthermore, when an overload (impact) is input to the lever 18, the guide portion 20 (slide portion 20A) can be made to interfere with the slide plate 16 in all radial directions around the longitudinal direction (sliding direction of the lever 18). The guide portion 20 is capable of interfering with the front wall and the rear wall of the housing gate 14 on the front side and the rear side, respectively. Therefore, the overload input to the lever 18 can be received by the slide plate 16, the housing gate 14 and the plate 12 through the guide portion 20 in the entire movable direction of the lever 18.

In addition, when the shift device 10 is assembled, the slide portion 20A is inserted into the slide plate 16 after the check spring 24 and the check pin 22 are inserted into the biasing box 12A in the plate 12 from the upper side. A lever 18 (except for the knob 18A) is inserted into the plate 12 from above. Next, the housing gate 14 is fixed to the plate 12 from the upper side, and the slide plate 16 (including the slide portion 20A) is held between the inner surface of the plate 12 and the upper wall of the housing gate 14. Therefore, the check spring 24, the check pin 22, the slide plate 16, the lever 18 and the housing gate 14 can be assembled from the upper side to the plate 12, and the assemblability of the shift device 10 can be improved.

In the present embodiment, the guide portion 20 of the lever 18 is slidably supported. However, the knob 18A of the lever 18 may be slidably supported.

Furthermore, in the present embodiment, the moderation surface 20D is provided on the lower surface of the check portion 20C of the lever 18, and the check pin 22 and the check spring 24 are provided on the lower side of the moderation surface 20D. However, the moderation surface 20D may be provided on the upper surface of the check portion 20C of the lever 18, and the check pin 22 and the check spring 24 may be provided on the upper side of the moderation surface 20D.

Further, in the present embodiment, the moderation surface 20D is provided on the lever 18 side, and the check pin 22 and the check spring 24 are provided on the plate 12 side. However, the check pin 22 (biasing portion) and the check spring 24 may be provided on the lever 18 side, and the moderation surface 20D may be provided on the plate 12 side.
