PROBLEM TO BE SOLVED: To cheaply provide a door opening/closing device for works clock which is provided with ornaments at each time indication point in a time indication part at every hour on the hour so as to move with full of variety. SOLUTION: Rotation by a motor 33a is transmitted to regularly rotate a first feed wheel 52a and a second feed wheel 54a via a series of wheels. By the coupling of projections 52a2 and 54a2 of the feed wheels with the grooves of each of Geneva wheels 55a, 56a and 57a, these wheels are intermittently rotated. To power shafts 27a, 28a and 29a rotating combined with each Geneva wheel, driving levers are attached and the levers are coupled with opening/ closing members placed capable of swinging together with the door so that a plurality of doors are opened and closed at arbitrary timings with a single motor.
