PROBLEM TO BE SOLVED: To provide an aspirator in which operability of a control lever and user friendliness can be improved.SOLUTION: An aspirator includes a case C storing a sheet member S, and opens a powder storage part S4 by peeling belt-like members S1, S2 while a delivery mechanism K delivering the sheet member S pitch by pitch is activated, and the peeled sheet member S is wound to be stored. The delivery mechanism K comprises: a driving gear 60 in which a recess 67 is arranged on an inner peripheral surface; and a control lever 50 which includes a swing shaft part 53 concentric with a revolving shaft of the driving gear 60. The swing shaft part 53 includes an elastic piece 54 which rotates the driving gear 60 by engaging with the recess 67 when pushing the control lever 50 toward the case C, and which slips between the elastic piece and the driving gear 60 by elastic displacement of the elastic piece with respect to the recess 67 when pulling the control lever 50 from the case C. |
