Abstract

A hot and cold water mixing device which comprises an inner housing (11) provided with a hot water inlet hole (17), a cold water inlet hole (18) and a mixed water delivery hole (19), and an outer housing (31) having openings (33, 34, 32) communicating with a hot supply passage (15), a cold water supply passage (16) and a mixed water supply passage (14). The inner housing (11) is inserted into the outer housing (31) to form a hot water passage (20), a cold water passage (35) and a mixed water passage (30) between the outer housing (31) and the inner housing (11). The hot water passage (20) and the mixed water passage (30) are formed by enclosing the hot water inlet hole (17) and the mixed water delivery hole (19) by the respective seal members (26, 29) which each are partly arranged so as to intersect with the circumferential line of the inner housing (11).
