Abstract: A strength of an outer side portion in a second direction of a shift body is increased. In a shift device, when a lever is placed in an ‘M’ position, a right avoidance hole of the lever avoids interference with a right restricting portion, rotational movement of a left restricting surface of the lever is restricted by a left restricting portion, and an operation to rotationally move the lever towards the right side is restricted. Furthermore, when the lever is placed in a ‘D’ position, a left avoidance hole of the lever avoids interference with the left restricting portion, rotational movement of a right restricting surface of the lever is restricted by the right restricting portion, and an operation to rotationally move the lever towards the left side is restricted. The right avoidance hole and the left avoidance hole can be made smaller, so that the strength of both outer side portions in a lateral directions of the lever can be increased.

A processor can command an operating gear change based on the signal output from the magnet sensor.

Abstract: A shift device comprises a shift lever and a shift knob. A driver moves the shift knob in a longitudinal direction when a shift change is conducted between plural traveling positions. The driver moves the shift knob, in a lateral direction, toward a driver's side when the shift change is conducted from a R position to a P position. When viewed from a vehicle rear side, the shift lever located at the traveling positions takes a first position where the shift lever is inclined, relative to its upright state, in a direction of separating its upper end portion with the shift knob from a driver's seat, whereas the shift lever located at the P position takes a second position where the shift lever is in the upright state or in a state which is closer to the upright state than the first position.
