In this shift device, in a case in which an external force has acted on a lever when an operating mechanism is causing the lever to pivot, a clutch mechanism permits rotation of a first detent plate with respect to a second detent plate, such that pivoting of the lever is permitted. Note that a restraining mechanism urges the lever toward a shift position. This enables to the restraining mechanism to urge the lever separately to the clutch mechanism, thereby enabling the degrees of freedom for setting a biasing load on the lever by the restraining mechanism to be increased.

Shift device

In a shift device, as a result of a rotor cam being rotated in a positive direction, and transmitting surfaces of the rotor cam pressing rotation surfaces of an urging cylinder, the urging cylinder is rotated in the positive direction, and a lever is moved rotationally towards a front side. Here, in a case in which a load towards the rear side is applied to the lever, the rotation surfaces are rotated in an opposite direction relative to the transmitting surfaces. As a result, the load towards the rear side being applied to the lever can be released.

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.

A shift lever device has a shift lever that is moved and whose shift position is changed, and a detent plate that is displaced due to the shift lever being moved. The shift lever device has a first lock bar and a second lock bar that can move toward the detent plate side or a side opposite from the detent plate, and, due to the first lock bar and the second lock bar engaging with portions of the detent plate, a range over which the detent plate is displaced is restricted, and a range of movement of the shift lever is restricted. The shift lever device has a cam that has a single engaged-with portion with which the first lock bar and the second lock bar engage, and, due to the cam being displaced, the first lock bar and the second lock bar are moved.

A shift lever device includes a shift lever that is rotated in a shift direction to change a shift position, and that is capable of moving in a direction different from the shift direction, a main shaft that rotates when the shift lever is rotated in the shift direction, and a housing that rotatably supports the main shaft. When the main shaft is moved in the direction different from the shift direction, a load is input from the shift lever to the main shaft in the opposite direction from a direction in which the main shaft is displaced from the housing.

A shift device for a vehicle, the shift device comprising: a shift body that is moved to change a shift position; and a restriction section provided with a first restriction member and a second restriction member, configured such that actuation of the first restriction member restricts movement of the shift body to a plurality of shift positions or within a shift range, and configured such that actuation of the first restriction member and the second restriction member, or actuation of the second restriction member alone, restricts movement of the shift body to a shift position.

A shift device includes: a shift mechanism that is provided with a shift body that is movable to change a shift position; at least one rotation section that is provided at the shift mechanism and that is rotated about a center axis line of the rotation section; at least one moving section that is provided at the shift mechanism and that is moved; and a detection body that detects a rotation position of the rotation section and detects a movement position of the moving section.

When a lock bar is moved in a state in which a cam is rotated and an abutting face is abutted on a cam face of the cam, the abutting face is abutted on a circumferential face of the cam at a location excluding a lock bar moving direction position with respect to a center of rotation. Accordingly, a movement stroke of the lock bar with respect to a rotation angle of the cam can be increased.

In a transmission mechanism, a motor is driven to rotate a rotation shaft, thereby rotating a rotor cam and a lock gear through a worm gear, a helical gear, and an intermediate gear. A cam is rotated integrally with the lock gear, thereby causing a lock bar to move to a position to restrict rotation of a knob and to a position to release rotation-restriction of the knob. A magnet is provided at the lock gear, and the magnet rotates integrally with the lock gear. Accordingly, the position of the rotor cam and the position of the lock bar can be detected from the position of the magnet.

A shift device, including: a shift body that is operated to change a shift position thereof; a biasing section that causes biasing force to act on the shift body; a retention track that, by placement of the biasing section thereon, causes the shift body to be retained at a shift position; a release track that, by movement of the biasing section thereon from the retention track, causes retention of the shift body at a shift position to be released; and a changer section that, after the biasing section has been moved from the retention track to the release track and moved along the release track, causes the biasing section to be moved from the release track onto the retention track and a shift position of the shift body to be changed by moving the biasing section at a specific occasion.

A shift device is configured including a restriction member and a release section. The restriction member stops a detent pin that has been moved at a release position, restricting movement of a shift lever to a third shift position when the shift lever is moved from a first shift position to a second shift position. When the shift lever has been moved at the second shift position, by the detent pin being moved to the release position from a non-release position, the release section releases the restriction of movement of the shift lever toward the third shift position by the restriction member.

A shift device includes a knob rotated to select a mode of a vehicle transmission. A rotary detent member is rotated to a rotation position corresponding to the selected transmission mode. The rotary detent member is coaxial with the knob. A connecting member connects the knob and the rotary detent member when located at the first position. The connecting member is disconnected from the knob when located at the second position. A motor rotates the connecting member and the rotary detent member. During a normal operation in which a certain condition is unsatisfied, a control circuit controls the motor to hold the connecting member at the first position. When the certain condition is satisfied, the control circuit controls the motor to move the connecting member to the second position and move the rotary detent member to a rotation position corresponding to a parking mode.
