Abstract:
A check valve that can prevent sticking of a valve body and reliably perform an opening and closing action in a check vale having a simple structure and that does not use biasing means on the valve body. A check valve has support pieces of a valve body protruding in the valve body direction on a circular base seat forming an outflow window in the center inserted in a circular groove where a support member (retainer) is formed between an outflow opening and a valve seat and on an open edge of the outflow window formed in the center of the base seat, and the support pieces of the support member (retainer) that support the valve body have linear or planar support parts on the top portion for leveling at least in a radial direction of the base seat.

Claim (Index 12):
The carburetor of  claim 11 , wherein the plurality of support pieces are positioned about an outflow window formed in a base of the support member and protrude from the base in a valve body direction;\n wherein each of the plurality of support pieces of the support member support the valve body on a linear or planar support part on a top portion for linearly leveling the valve body at least in a radial direction of the base; wherein each of the plurality of support pieces has a linear or planar support part on the top portion for leveling at least in a radial direction of the base seat by raising each of the plurality of support pieces to face in a direction to intersect a direction toward a center of the base seat.
