<P>PROBLEM TO BE SOLVED: To provide a water-purifying cartridge positioning structure capable of uniformly maintaining the width of a watercourse of a raw water passage to eliminate the inclination in the circumferential direction of the incursion of water so that the positioning of a water-purifying cartridge, the rotation stop, the attachment and detachment or the like can be easily and surely made and, at the same time, that excessive load can not be applied in the case of attachment and detachment. <P>SOLUTION: The water-purifying cartridge positioning structure is so constituted that a fitting section is formed between an entrance section of a cartridge storage section of a holding section and the outer circumferential end section on a downstream side of a water-purifying cartridge, a projection is formed in one member forming the fitting section and a recess section is formed in the other member, the projection and the recess section are fitted to each other when the water-purifying cartridge is stored in the cartridge storage section of the holding section and that the movement of the mutually relative circumferential direction can be controlled. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
