ムホース。[Scope of Claim for Utility Model Registration] In a vacuum hose with a built-in check valve in which a cylindrical check valve is built into a flexible hose, the inner diameter of the portion including one end of the vacuum hose is equal to the outer diameter of the check valve. Alternatively, the diameter may be slightly enlarged to form a stepped portion on the inner peripheral surface of the vacuum hose, and the check valve may be inserted through the enlarged diameter portion and installed in a portion where the diameter is not expanded beyond the stepped portion. Vacuum hose with built-in check valve.
