Engine starting device

An engine starting device comprising:

• a portable unit which can be carried by a driver, and in which a transmitting unit capable of transmitting an ID code inherent to a vehicle is arranged;
• a control unit which includes a substrate on which a receiving unit capable of receiving the ID code transmitted from the transmitting unit, and a determination unit configured to determine whether the ID code received by the receiving unit is a pre-registered legitimate ID are formed;
• a main body part which includes an operation knob configured to be rotationally operated between an off position at which an engine of the vehicle is to be stopped and an on position at which the engine is to be started, and which is fixed between a bar-shaped handle and a speed meter of the vehicle;
• and
• a regulation unit which is configured to regulate a rotational operation of the operation knob, and which is configured to release a rotation-regulated state of the operation knob on condition that the ID code received by the receiving unit is determined a legitimate ID by the determination unit, wherein:
• the main body part is fixed to a handle bracket provided at a center portion of the bar-shaped handle of the vehicle, such that the regulation unit is disposed on and attached to a right side part of the main body part and the control unit is disposed on and attached to a left side part of the main body part, as seen from a driver seat-side of the vehicle,
• the handle bracket is formed with a pair of protrusions at the center portion of the bar-shaped handle, said pair of protrusions extending orthogonally underneath the bar-shaped handle,
• the main body part is fixed to the pair of protrusions, and
• one of the pair of protrusions is adjacent to the regulation unit, and the other of the pair of protrusions is adjacent to the control unit.
