（Ａ）１ａの内面を滑るだけなので、切り替えの操作は
楽に行なわれる。これは弁４ａについても同様である。The reason why the water leakage is suppressed well is as follows.
The valve 3 is moved toward the valve seat 10a or the valve seat 10b by the valve spring 3c.
This is because a is pressed. The switching operation of switching the valve 3a from the valve seat 10a to the valve seat 10b or from the valve seat 10b to the valve seat 10a has good operability. That is, when the valve 3a is disengaged from the valve seat 10b or the valve seat 10a, the valve 3a is receded linearly against the valve spring 3c. Since the user only slides on the inner surface of 1), the switching operation is performed easily. This is the same for the valve 4a.

Therefore, the valve 4a exhibits a reciprocating motion that moves linearly in the vertical direction against the valve spring 4c. The valve 4a is provided with a valve seat 10c provided at an edge of the valve chamber communication hole (E).
Alternatively, the valve chamber communication hole is brought into contact with a valve seat 10d provided at an edge portion of the valve chamber communication hole (F) to close the valve chamber communication hole. Since the tip of the valve 4a is also spherical, it comes into abutment with good seating and eliminates water leakage.
