PROBLEM TO BE SOLVED: To solve the problem of conventional dispensers that there is a risk that their lids are lost by developing an opening/closing device of dispensers which is convenient and prevents loss of lids and which takes into consideration resource saving, energy conservation and waste reduction. SOLUTION: The opening/closing device of dispensers includes: a dispensing container (A); a rotary driving mechanism (B); a reciprocating driving mechanism (C); and an opening/closing driving mechanism (D). The device has a function that when a rotating body (R) is rotated forward relative to a holding body (H), a lid is opened to dispense an object to be delivered and a function that when the rotating body is rotated backward, the lid is closed to retract the object to be delivered. The opening/closing device of dispensers solves the conventional problems of dispensers and is applicable to various types of dispensers and to an opening/closing device of dispensers which is repeatedly used.
