Abstract

PROBLEM TO BE SOLVED: To provide a check valve and a seating valve having little deformation of a seat, and a satisfactory sealability. SOLUTION: This check valve is composed of an accommodation space 36 formed in a fluid passage 8; a body 41a formed with a passage hole 41b along the center axis; a head part 41c raised in a one side end face of the body 41a along the outer periphery of the passage hole 41b and formed with a seat 41d at the end part; a seating valve 41 arranged with one end face on the opposite side of the head part 41c allowed to abut to the bottom surface 25a of a recess 25; a valve element 32 having a seat surface abutting to the seat 41d; an elastic member 33 compressedly accommodated an accommodation space 36 and urging the valve element 32 in the direction of the seat 41d; and a fixing member 31 for fixing the seating valve 41 to the bottom of the recess 25 by applying a load to a shoulder part of the body 41a in the direction of the center axis. With this arrangement, a thin wall part 41g is formed between a loading point of the shoulder part 41e and the seat 41d.
