  The present invention relates to an engine starting device that permits starting of an engine on the condition that an ID code from a transmission means is determined to be an authorized one registered in advance.

  In order to prevent theft of vehicles that frequently occur in recent years, the vehicle includes a transmission unit that can transmit a vehicle-specific ID code while being carried by a driver, and a reception unit that can receive the ID code. A so-called smart entry system has been proposed that allows various operations of the vehicle including engine start, provided that the ID code is genuine. For example, in the case of a smart entry system in a motorcycle, when the driver carrying the transmission means (electronic key) approaches the vehicle, the reception means receives the ID code transmitted from the transmission means, and is registered in advance. Whether the engine is present or not is determined, and the engine start operation is enabled only when the engine is genuine.

  However, a motorcycle equipped with the smart entry system as described above conventionally has an operation knob that can be rotated on condition that it has been determined that a legitimate ID code has been received. Thus, an ignition switch device has been proposed in which the engine can be started (see, for example, Patent Document 1). In such an ignition switch device, the operation knob can be rotated from the off position to the on position or the lock position, and the engine is started at the on position and the steering wheel of the vehicle is locked at the lock position.
