PROBLEM TO BE SOLVED: To reduce a consumed electric power in a code number comparison device and make its constitution simple, in a theft prevention device by which above communication is carried out before the start of a prime mover. SOLUTION: When a key 1 is inserted in a key cylinder and a key insertion switch 2 is opened or closed, this is inputted to a main relay control part 15. This control part 15 outputs a raw signal to the base of a first transister 11 based on this input and a coil 21a is made in an electrified state. Thereby, a contact point 21b is closed and an electric power is supplied to a theft prevention control device 8 and an engine control device 9. The constitution of above respective devices 8, 9 can be made simple, due to that the electric power is not consumed until the key insertion switch 2 is closed and there is no need of sleep mode. |
