Shift lever device

A shift lever device includes: a lever main-body; a hollow knob provided at a lever main-body distal end portion; a shift-button rotatably mounted to the knob; and a rod that is inserted-through interior of the lever main-body. The shift-button has a contact surface extending in direction of being away from a rotating-shaft of the shift-button, and that, when the shift-button rotates with respect to the knob, contacts an upper end portion of the rod and lowers the rod. Given that direction orthogonal to axial-direction of the rotating-shaft on plane orthogonal to axis of the rod is reference-direction, and that, among tangent-lines at contact points of the contact surface and the rod, tangent-line on plane orthogonal to the rotating-shaft is reference tangent-line, rotation range of the shift-button is set such that, partway through rotation, the reference tangent-line passes position at which the reference tangent-line becomes parallel to the reference-direction.
