PROBLEM TO BE SOLVED: To normally drive a load even when a key switch is switched to a starting position while performing timer operation in a load driving device for supplying electric power to the load only when a timer performs the timer operation when starting an engine. SOLUTION: This load driving device is provided with a timer operation time lengthening switch 7A connected to both ends of a timer capacitor C1 via a current limiting resistance R10 and bypassing a part of a charging current of the timer capacitor C1 from the timer capacitor when in an ON state and a timer operation time lengthening switch driving circuit 7B for holding the timer operation time lengthening switch 7A in an ON state by imparting a driving signal to the timer operation time lengthening switch 7A while switching a movable contact point 3a of the key switch 3 to a starting contact point 3d.
