A fan type chemical diffusing apparatus is disclosed which enables an apparatus main body, a chemical receptacle and a power supply housing to be made independent in volume from each other and which makes it possible to readily establish an amount of retention of a chemical relative to a rate of airflow produced by a fan, and a length of time period for its service. Disclosed also is a chemical receptacle that prevents chemical impregnated carrier particles from being seized in a space between the end face of the receptacle main body and a lid body, as well as a clip type fastener by which the apparatus can be fastened firmly to an object regardless of its thickness. <;??>;The fan type chemical diffusing apparatus includes the apparatus main body made of a fan that produces an air flow, a motor for driving the fan and an airflow opening through which the airflow produced by the fan passes; the chemical receptacle for accommodating a chemical impregnated body therein that is impregnated with a chemical, the chemical receptacle having vent holes; and a power supply housing for receiving a power supply therein, the power supply powering the motor, wherein the chemical receptacle and the power supply housing are adapted to be detachably loaded in the apparatus main body and when loaded are each positioned therein so as to receive essentially no limitation in volume from the other. <;??>;The chemical receptacle for use with a fan type chemical diffusing apparatus for volatilizing and diffusing a chemical in a chemical impregnated body accommodated in the chemical receptacle by means of an airflow produced by a fan, comprises: a cylindrical receptacle main body having its cylindrical wall closed with its one end wall formed with a large number of vent holes; and a cylindrical lid body having its cylindrical wall closed with its one end wall formed with a large number pf vent holes, wherein the cylindrical wall of the lid body is adapted to be fitted into and with
