In a detector that constitutes an in-tank valve, an attachment part formed on one end thereof is arranged in facing relation to a connector of a drive unit, and arm members of a bracket, which is substantially U-shaped in cross section and is fixed to the connector, are inserted in and engaged with engagement holes of the attachment part. Thus, the detector is always retained firmly in a state of being pulled to the side of the drive unit by elastic forces of the bracket.
1. An in-tank valve disposed in a tank in which a high pressure gas is stored in interior thereof, comprising a body including a valve configured to open and close a flow path, and a detector configured to detect a temperature of the high pressure gas,
wherein a retaining unit configured to retain the detector with respect to the body is disposed between the body and the detector, and the retaining unit imparts a resilient force in directions to cause the body and the detector to approach one another mutually,
wherein the retaining unit comprises:
a base member held on one of the body and the detector to extend in a radial direction of the detector, at least a portion of the base member being inclined toward one of the body and the detector;
a pair of arm members configured to extend with respect to the base member toward another one of the body and the detector; and
hooks provided at distal ends of the arm members and folded toward the base member,
wherein the hooks are inserted into the other of the body and the detector and engage with a surface of the other of the body and the detector opposite to the base member, and
the retaining unit is a separate body apart from the body and the detector.
2. An in-tank valve disposed in a tank in which a high pressure gas is stored in interior thereof, comprising a body including a valve configured to open and close a flow path, and a detector configured to detect a temperature of the high pressure gas,
wherein a retaining unit configured to retain the detector with respect to the body is disposed between the body and the detector, and the retaining unit imparts a resilient force in directions to cause the body and the detector to approach one another mutually, wherein the retaining unit comprises:
a base member formed on one of the body and the detector to extend in a radial direction of the detector, at least a portion of the base member being inclined toward the one of the body and the detector;
arm members configured to extend with respect to the base member toward a side of another one of the body and the detector; and
hooks provided at distal ends of the arm members and folded toward the base member,
wherein the hooks are inserted into the other of the body and the detector and engage with a surface of the other of the body and the detector, and
the retaining unit is formed integrally with the one of the body and the detector.
