Abstract
A shaft body (12) is rotatable around an axial line (C-C). A first valve element (13a) is located between a first opening (11a) and a second opening (11b) and it has a first notch (13a1). A second valve element (13b) is located between first opening (11a) and a third opening (11c) and it has a second notch (13b1). By rotating first and second valve elements (13a, 13b) around the axial line (C-C) as a center (O), an operation for opening and closing first and second notches (13a1, 13b1) can be performed.
