Abstract: A fixing structure includes a housing including a first hole, an input member including a second hole, and rotating relative to the housing, depending on input of rotational force, a torsion spring being biased so as to return, to a predetermined reference position, a position of the input member relative to the housing, and a fixing member inserted into the first hole and the second hole in a state where the input member is rotated against biasing force of the torsion spring from the reference position to a predetermined rotational position. The fixing member includes a first insertion portion including a part press-fitted into and fixed to the first hole, and a second insertion portion including a part inserted into the second hole, and fixes the input member at the predetermined rotational position.

Abstract: A disk type valve which is arranged such that a pair of fixed and movable disks which are superposed one upon the other are disposed in a cylindrical valve casing in such a manner that the planes of the disks are perpendicular to the axis of the valve casing, these disks being provided with notches or openings for passing water, and the movable disk being engaged with the distal end of a spindle which is inserted into the valve casing from one end thereof in parallel to the axis of the valve casing, wherein the movable disk is disposed at the other end of the valve casing, and the spindle is passed through an insertion portion provided in the fixed disk and engaged with the movable disk.
