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.COPYRIGHT: (C)2015,JPO&INPIT【課題】操作レバーの操作性を高めることができるとともに使い勝手も良くなる吸引器具を提案する。【解決手段】本発明の吸引器具は、シート部材Sを収納するケースCを有し、シート部材Sを1ピッチ分ずつ送り出す繰出機構Kの作動に伴い、帯状部材S1、S2を剥離させて粉体収容部S4を開封し、剥離後のシート部材Sを巻き取って収納するものであって、繰出機構Kは、その内周面に凹部67を設けた駆動歯車60と、駆動歯車60の回転軸と同心となる揺動軸部53を有する操作レバー50とを備え、揺動軸部53は、操作レバー50のケースCへ向けた押し込み変位にて凹部67に係合して駆動歯車60を回転させる一方、操作レバー50のケースCからの引き出し変位にて凹部67に対して弾性変位することで駆動歯車60との間で空転する弾性片54を有することを特徴とする。【選択図】図1
