PURPOSE:To prevent the abrasion of faucet construction and a drop in the sealing quality thereof by providing a divisional plate with both ends radiused in the faucet construction of internal and external turbine wheel chambers. CONSTITUTION:Divisional plate insertion grooves 23 and 24 are formed all around a high and medium pressure external wheel chamber 1 and a high pressure internal wheel chamber 3, and a divisional plate 25 is inserted therein for sealing steam. The divisional plate 25 is made thin and the deflection thereof is used for close fitting to the wheel chamber side. Also, both ends of the divisional plate 25 are radiused 'R', thereby ensuring the close fitting of the divisional plate 25 to said grooves 23 and 24 at the wheel chamber side, even if there should occur any elongation on internal and external wheel chambers.
