PROBLEM TO BE SOLVED: To provide a filter cap of a spray valve for an aerosol vessel which can form a small hole for a filter of the stable shape by a retrofittable separate component. SOLUTION: The filter cap prevent any foreign matters from flowing into a housing 3 when the filter cap is fitted to a pipe part 17 provided on a housing bottom part 3b having a flow-in hole 3a, and is formed on a sleeve 20 which is externally inserted in the pipe part 17. A bottom side of the sleeve is closed by a bottom surface part 20a, and a plurality of recessed parts 21 are formed in a radial direction so as to form small holes 26 for a long filter in an inner circumferential surface of the sleeve 20 in an abutted condition on an outer circumferential surface of the pipe part 17. In addition, flow-in passages 29 and 27 for allowing the content to flow into the housing 3 through a flow-in hole 3a in the housing bottom part 3b via the small holes 26 for the filter from the aerosol vessel are formed in a tip part area and a bottom surface part area of the sleeve 20, respectively. |
