Abstract: A hub assembly with a hub body connected to a tube from an external appliance, a hub outer casing which is coupled to the hub body and forms a liquid passage, a slitted separating wall disposed in the liquid passage in the hub outer casing, a filter disposed on the living body-side of the separating wall to allow the passage of gas and regulate the passage of liquid, and a ventilation passage which communicates between the liquid passage and the outside of the hub outer casing by way of the filter, wherein an end portion of the ventilation passage on the separating wall side of an opening portion facing the liquid passage is in a location at most 10 mm toward the distal end side relative to the distal end of the separating wall.
