Abstract

PURPOSE:To reduce noises by providing a spiral groove on the surface of a gear which is rotated by a driving motor, by indicating the computed operation hour of the timer by using the amount of rotation of an indicating plate which is rotated by said groove. CONSTITUTION:An engaging knob 14 which is provided on the rotatable indicating plate 12 is engaged with the spiral groove 11a provided on the surface of the rotating gear 11 which is driven by the torque of the driving motor. The amount of rotation of said rotating indicating plate 12 is observed through an observing window 12A, and the operating hour of the timer is computed and indicated.
