A shift lever device comprising: a lever main body that is hollow and is shaft-shaped; a knob that is hollow and is provided at a distal end portion of the lever main body; a rotating member that is disposed within the knob and is rotatably mounted to the knob; a rod that is inserted through an interior of the lever main body; and an urging member that is disposed at the interior of the lever main body, and that is configured to urge the rod toward an upper side, wherein: the rotating member has a contact surface that extends in a direction of moving away from a rotating shaft of the rotating member, and that, when the rotating member rotates with respect to the knob, contacts an upper end portion of the rod and lowers the rod, and given that a direction orthogonal to an axis of the rotating shaft on a plane orthogonal to an axis of the rod is a reference direction, and that, among tangent lines at contact points of the contact surface and the rod, a tangent line (Lct) that is on a plane orthogonal to the rotating shaft is a reference tangent line (Lct), a rotation range of the rotating member is set such that the reference tangent line (Lct) passes a position at which the reference tangent line (Lct) becomes parallel to the reference direction partway through rotation of the rotating member, characterized in that a guide hole, that supports the rod such that the rod slides freely, is formed in the knob, and the contact surface is inclined with respect to the axis of the rotating shaft. a lever main body that is hollow and is shaft-shaped; a knob that is hollow and is provided at a distal end portion of the lever main body; a rotating member that is disposed within the knob and is rotatably mounted to the knob; a rod that is inserted through an interior of the lever main body; and an urging member that is disposed at the interior of the lever main body, and that is configured to urge the rod toward an upper side, wherein: the rotating member has a contact surface that extends in a direction of moving away from a rotating shaft of the rotating member, and that, when the rotating member rotates with respect to the knob, contacts an upper end portion of the rod and lowers the rod, and given that a direction orthogonal to an axis of the rotating shaft on a plane orthogonal to an axis of the rod is a reference direction, and that, among tangent lines at contact points of the contact surface and the rod, a tangent line (Lct) that is on a plane orthogonal to the rotating shaft is a reference tangent line (Lct), a rotation range of the rotating member is set such that the reference tangent line (Lct) passes a position at which the reference tangent line (Lct) becomes parallel to the reference direction partway through rotation of the rotating member, characterized in that a guide hole, that supports the rod such that the rod slides freely, is formed in the knob, and the contact surface is inclined with respect to the axis of the rotating shaft. the rotating member has a contact surface that extends in a direction of moving away from a rotating shaft of the rotating member, and that, when the rotating member rotates with respect to the knob, contacts an upper end portion of the rod and lowers the rod, and given that a direction orthogonal to an axis of the rotating shaft on a plane orthogonal to an axis of the rod is a reference direction, and that, among tangent lines at contact points of the contact surface and the rod, a tangent line (Lct) that is on a plane orthogonal to the rotating shaft is a reference tangent line (Lct), a rotation range of the rotating member is set such that the reference tangent line (Lct) passes a position at which the reference tangent line (Lct) becomes parallel to the reference direction partway through rotation of the rotating member, characterized in that a guide hole, that supports the rod such that the rod slides freely, is formed in the knob, and the contact surface is inclined with respect to the axis of the rotating shaft.
