The knob 16E is grippable by a vehicle occupant (in particular, a driver), and the knob 16E is manipulated in the front-rear direction in a state of being gripped by the occupant, and the lever 16 is slid in the front-rear direction. The lever 16 is slid back and forth so that the shift position can be changed, and the shift position of the lever 16 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 16A of the lever 16, a substantially rectangular columnar check pin 24 (see FIG. 3) as a moderation member constituting the shift biasing means is coaxially fitted, and the check pin 24 is biased While being guided by the box 16A to be movable in the vertical direction, the upper surface is curved in a convex shape in the longitudinal direction.

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

In the shift device 10 configured as described above, the guide portion 16B of the lever 16 is supported by the housing gate 14 (slide plate 14A) of the plate 12 via the spring 22, the retainer 18 and the roller 20. When the knob 16E of the lever 16 is operated in the longitudinal direction, the lever 16 is slid in the longitudinal direction while the guide portion 16B is slid in the longitudinal direction along the slide plate 14A, and the shift position of the lever 16 is changed. Ru. Furthermore, the sensor substrate 30 detects the sliding position of the lever 16 in the front-rear direction of the magnet 28, whereby the sliding position of the lever 16 in the front-rear direction is detected. Further, the check pin 24 of the lever 16 is brought into contact with the detent surface 14C of the housing gate 14 (check portion 14B) by the biasing force of the check spring 26 of the lever 16, whereby the lever 16 is biased to the “H” position side. Ru.

Here, when the lever 16 is slid in the front-rear direction, the roller 20 is rotated by contact with the slide plate 14A. For this reason, the sliding resistance between the lever 16 (guide part 16B) and the slide plate 14A can be reduced, the sliding resistance in the front-rear direction of the lever 16 can be reduced, and the sliding performance can be improved. As a result, the operation feeling of the knob 16E in the front-rear direction by the occupant can be improved. Furthermore, for example, even when the shift device 10 is provided with a drive mechanism (not shown) and the lever 16 is slid to the specific shift position by the drive force of the drive mechanism, the sliding performance of the lever 16 by the drive mechanism can be improved.

Further, in the guide portion 16B of the lever 16, the spring 22 biases the roller 20 via the retainer 18, and the roller 20 is in contact with the slide plate 14A. Therefore, when the knob 16E is operated in the front-rear direction and the lever 16 is slid in the front-rear direction, rattling of the lever 16 (guide portion 16B) with respect to the slide plate 14A can be suppressed, and rattling of the knob 16E can be suppressed. .

Furthermore, each pair of rollers 20 of the guide portion 16B of the lever 16 abuts on the slide plate 14A in the inclination direction with respect to the left-right direction (slide width direction of the lever 16) and the up-down direction (slide vertical direction of the lever 16). ing. Therefore, the pair of upper and lower rollers 20 in the left guide portion 16B are in contact with the slide plate 14A on the left side in the left direction, and the upper side of the slide plate 14A on the upper side. It is possible to have the function of the pair of rollers 20 to be abutted and the function of the pair of rollers 20 to be abutted in the lower direction of the slide plate 14A on the lower side. Further, the pair of upper and lower rollers 20 in the right guide portion 16B is in contact with the slide plate 14A at the upper side and the function of the pair of rollers 20 in the right side. It is possible to have the function of the pair of rollers 20 in contact and the function of the pair of rollers 20 in the lower side abutting on the slide plate 14A in the lower direction. Thereby, the pair of rollers 20 (including the retainer 18 and the spring 22) may be omitted as compared to the case where the rollers are provided in the vertical direction and the three directions of the left and right directions in the left and right guide portions 16B. It is possible to reduce the number of parts.

A magnet 28 is provided at the lower end of the lever 16. Therefore, unlike the case where the magnet 28 is provided on the interlocking member interlocked with the sliding of the lever 16 in the front-rear direction, the accuracy of the position of the magnet 28 with respect to the sliding position of the lever 16 in the front-rear direction can be increased. It is possible to improve the detection accuracy of the sensor substrate 30 at the slide position in the front-rear direction of the sensor. 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 16, the guide portion 16B can be made to interfere with the housing gate 14 in all radial directions around the longitudinal direction (sliding direction of the lever 16), and the guide portion 16B can be interfered with the front wall (front) of the housing gate 14 on the front side, and the guide portion 16B can be interfered with the rear wall (rear) of the plate 12 on the rear side. Therefore, the overload inputted to the lever 16 can be received by the housing gate 14 and the plate 12 through the guide portion 16B in all directions (the entire movable direction of the lever 16).

The bottom wall of the retainer 18 is in contact with the bottom surface of the biasing hole 16D at a lower position of the guide portion 16B of the lever 16 by the check spring 26 biasing the lever 16 downward (plate 12 side). It is done. For this reason, when a load to the lower side is applied to the knob 16E of the lever 16 by the occupant, rattling to the lower side of the lever 16 can be suppressed.

In the present embodiment, the lever 16 is provided with the roller 20 (including the retainer 18 and the spring 22). However, with or instead of this, the housing gate 14 may be provided with a roller 20 (including a retainer 18 and a spring 22).

Furthermore, in the present embodiment, the guide portion 16B of the lever 16 is slidably supported. However, the knob 16E of the lever 16 may be slidably supported.

Further, in the present embodiment, the check pin 24 and the check spring 26 are provided on the lever 16 side, and the check portion 14B is provided on the plate 12 side (housing gate 14). However, the check portion 14B may be provided on the lever 16 side, and the check pin 24 and the check spring 26 may be provided on the plate 12 side.

Furthermore, in the present embodiment, the magnet 28 is provided on the lever 16 side, and the sensor substrate 30 is provided on the plate 12 side. However, the sensor substrate 30 may be provided on the lever 16 side, and the magnet 28 may be provided on the plate 12 side.
