1. An electronic shift control apparatus comprising:
a shift dial rotatable with respect to a main housing for selecting one of shifting ranges of a vehicle when being rotated;
a rotator coupled to the shift dial to rotate with the shift dial;
a groove plate coupled to the rotator to rotate with the rotator;
a Printed Circuit Board (PCB) fixed to the main housing and outputting a shifting range signal selected by the shift dial to a Transmission Control Unit (TCU) electrically connected to the PCB; and
a haptic motor assembly fixed to the main housing, connected to the groove plate, controlled to operate by the PCB, and generating a haptic signal when operating,
wherein the haptic motor assembly includes:
a motor housing fixed to the main housing;
a haptic motor inserted and fixed in the motor housing, electrically connected to the PCB, and controlled to be operated by the PCB; and
a roller rotatably coupled to the motor housing and being in contact with the groove plate,
wherein the motor housing includes an elastic protrusion integrally protruding in one direction from the motor housing,
wherein the motor housing is in contact with the main housing through the elastic protrusion,
wherein the elastic protrusion protrudes in an opposite direction of the roller, and
wherein when the elastic protrusion comes in contact with the main housing, a force that moves the motor housing toward the groove plate is applied to the motor housing by elasticity of the elastic protrusion, whereby a contact force between the roller and the groove plate is maintained.
