Abstract: Provided is a hollow fiber membrane module that allows reducing pressure loss of a dry gas and a moist gas. A hollow fiber membrane module has: a hollow fiber membrane bundle; a case in which the hollow fiber membrane bundle is accommodated; a pair of sealing and fixing parts that fixes the hollow fiber membrane bundle to the case; intra-membrane channels; and extra-membrane channels. Moisture in the moist gas is supplied into the dry gas by virtue of the membrane separation effect of the hollow fiber membranes. A first channel is provided, which runs through the case from one end side to the other end side and through which part of the dry gas flows without passing through the intra-membrane channels.

Abstract: Provided is a gasket mounting structure capable of preventing a gasket from being mounted in a wrong direction. The gasket mounting structure is configured such that, when a jig 200 is inserted into a gasket 100 from a large-diameter inner peripheral surface portion 124 side, a small-diameter outer peripheral surface portion 210 is press-fitted into an inner peripheral surface of a seal projection 122 to result in a state in which the gasket 100 is held by the jig 200 and, when the jig 200 is inserted into the gasket 100 from a small-diameter inner peripheral surface portion 123 side, the small-diameter outer peripheral surface portion 210 does not reach a position at which the small-diameter outer peripheral surface portion 210 can come into contact with the seal projection 122.
