PROBLEM TO BE SOLVED: To provide a powder medicine administering instrument which is easy to assemble and absorbs a variation in dimension.SOLUTION: A first main unit 5 is provided with an engaging projection 10 that engages with a second main unit 6. Insertion openings 6c, 6d and 6e for inserting the engaging projection 10 are formed on the second main unit 6. Inclined surfaces 10c are formed on parts of the engaging projection 10 that engages with opening edges 6f of the insertion openings 6c, 6d and 6e, and pushing force is generated elastically between the engaging parts. A slider 7 is held by the first main unit 5 and the second main unit 6 in such a way that the slider is movable relative to the main units.COPYRIGHT: (C)2009,JPO&INPIT【課題】より容易に組み付けることができるとともに、寸法ばらつきを吸収することが可能な粉末薬剤投与器を得る。【解決手段】第一本体部5に第二本体部6と係合する係合突起部10を設けるとともに、第二本体部6に当該係合突起部10を挿通させる挿通口6c,6d,6eを形成し、係合突起部10が挿通口6c,6d,6eの開口縁6fと係合する部分に傾斜面10cを形成するとともに、当該係合する部分同士で弾性的に押圧力を生じさせ、第一本体部5に第二本体部6とでスライダ7を相対移動可能に挟持するようにした。【選択図】図3
