ABSTRACT:
Disclosed is a small-sized joint for joining hydrogen gas running route-forming members, which can surely prevent the leakage of hydrogen gas, and a portable hydrogen flame ionization gas detector that can prevent the leakage of hydrogen gas to achieve high safety.The joint comprises a metallic base having an internal space at least one end of which is opened, and a ring-like sealing member composed of an elastic material and arranged at opening edge of the metallic base, wherein a hydrogen gas running route-forming member is fixed in a state inserted into an internal space of the metallic base through the sealing member, and the sealing member is squeezed to gastightly seal the space, whereby one hydrogen gas running route-forming member is removably joined. In the gas detector, the joint is used to form a hydrogen gas running route.
