PROBLEM TO BE SOLVED: To provide an idle rotation control device capable of easily changing an engine rotary speed in idling in response to an interest, taste or uses, by easily changing the engine rotary speed of an engine in idling only by operating an input means. SOLUTION: This idle speed control device has a DC motor 37 opening and closing a throttle valve 34 for changing opening of an intake passage 32, by opening and closing the intake passage 32 connected to the engine 12. A CPU 37 controls the opening of the intake passage 32 by driving the DC motor. A motorcycle 1 is attached with a mode switch 66 and a reset switch 67 for inputting a target engine speed of the engine in idling, and the target engine speed inputted by these mode switch 66 and reset switch 67 is stored in a storage part 72. The CPU 37 controls the opening of the intake passage 32 in idling in response to the target engine speed stored in the storage part 72. COPYRIGHT: (C)2008,JPO&INPIT
