The ball seat (12A) includes a plurality of protrusions (12e) jutting out from the ball seat (12A) and inserted into a plurality of through holes (11b) formed in a bottom portion of the housing (11). The protrusions (12e) having pierced through the through holes (11b) are staked at their distal portions (e2). The protrusion (12e) of the ball seat (12A) has a large diameter portion (e1), whose diameter is larger than an inner diameter of the through hole (11b) of the housing (11), at its proximal portion proximal from the distal portion (e2) thereof.",
