ABSTRACT:
A connector housing of a valve-equipped connector is integrally formed from a tube connection section at a first axial side; a pipe insertion section at a second axial side; and a valve housing section between the tube connection section and the pipe insertion section. The valve housing section is formed with an adequately large inner diameter. A main valve body and a compression coil spring for biasing the main valve body to the first axial side so that it abuts the inner surface of the housing are stored in the valve housing section. A cylindrical bushing is fitted to the first axial side of the pipe insertion section of the connector housing, and a valve cap for receiving a second axial end of the compression coil spring is formed integrally at the first axial end of the cylindrical bushing.
