Abstract
In a shift device, contact projections of a rotation cylinder make contact with side faces of recesses of an detent plate due to an urging force so as to urge a lever toward a shift position side. The contact projections make line contact with the side faces of the recesses. This enables the contact amount between the contact projections and the side faces of the recesses to be increased, enabling the contact pressure between the contact projections and the side faces of the recesses to be lowered.
Claims8
A shift device comprising:
- a shift body that is configured to rotate with respect to a vehicle body side about an axis of rotation of the shift body to change a shift position;
- a contact body that is fixed on the vehicle body side with no relative movement between the contact body and the vehicle body side;
- and
- a contact member that is provided on a shift body side and configured to rotate integrally with the shift body about the axis of rotation of the shift body with no relative rotation between the contact member and the shift body, that faces the contact body in a direction along the axis of rotation of the shift body,
- wherein:
- a projection portion projects in the direction along the axis of rotation of the shift body, and is formed integrally at one of the contact body or the contact member with no relative movement between the projection portion and the one of the contact body or the contact member,
- a recess portion is recessed in the direction along the axis of rotation of the shift body, and is formed at the other of the contact body or the contact member,
- the projection portion and recess portion are configured to face in the direction along the axis of rotation of the shift body, the projection portion and recess portion make line contact or surface contact due to an urging force in the direction along the axis of rotation of the shift body such that the shift body is urged toward a shift position side,
- the projection portion extends along a radial direction of rotation of the shift body relative to the axis of rotation of the shift body, a length of the projection portion in the radial direction is longer than a width of the projection portion along a circumferential direction of rotation of the shift body, and
- the recess portion extends along the radial direction relative to the axis of rotation of the shift body, a length of the recess portion in the radial direction is longer than a width of the recess portion along the circumferential direction.
