PROBLEM TO BE SOLVED: To provide an aroma generator capable of facilitating refill work of liquid aroma and evaporating and diffusing the liquid aroma at an optional timing of a user, and to provide a retaining member for use in the aroma generator.SOLUTION: An aroma generator 100 includes a container member 1, a retaining member 3, and an evaporation member 4. The container member 1 is formed into a bottomed cylindrical shape with an opening part 14 at one end, stores essential oil, and has a male screw part 12a. The retaining member 3 includes a female screw part 33 with which the male screw part 12a is engageable, is formed into a cylindrical shape, and stores and retains the container member 1. The evaporation member 4 is attached to at least either one of the container member 1 and the retaining member 3. The essential oil 1A infiltrates the evaporation member 4 and evaporates therefrom. The retaining member 3 has: a first cylindrical part 31 from one end of which the container member 1 is inserted and a second cylindrical part 32 that is provided at the other end of the first cylindrical part 31 and where the evaporation member 4 is exposed to the outside from an end opposite to the first cylindrical part 31.COPYRIGHT: (C)2014,JPO&INPIT【課題】液状香料の補充作業を簡便に行うことができつつ、使用者の任意のタイミングで液状香料の蒸発・拡散を行うことができる芳香器及び芳香器に用いる保持部材を提供する。【解決手段】芳香器100は、容器部材1と、保持部材3と、蒸発部材4と、を備える。容器部材1は、一端に開口部14を有する有底筒状に形成され、精油1Aを収容するとともに、雄ねじ部12aが設けられる。保持部材3は、雄ねじ部12aが係合可能な雌ねじ部33が設けられるとともに、筒状に形成され、容器部材1を収容して保持する。蒸発部材4は、容器部材1及び保持部材3のうち少なくともいずれか一方に取り付けられる。蒸発部材4には、精油1Aが浸透して蒸発する。保持部材3は、容器部材1が一端から挿入される第1筒状部31と、第1筒状部31の他端に設けられ、第1筒状部31と反対側の端部から外部に蒸発部材4が露出する第2筒状部32と、を有する。【選択図】図3
