摘要： The ink cartridge has a communication unit for allowing an ink storage chamber to communicate with a space outside a housing. The communication unit includes a communication port formed on an outside surface of the housing, a merging channel having an end which communicates with the communication port, and a plurality of branch channels, each having an end which communicates with the merging channel and the other end which communicates with the ink storage chamber. In the branch channel, while ink flows backward, the ink flowing from the merging channel branches into the first branch channel and the second branch channel. At the same time, a ratio (Q1/Q2) between an ink flow rate in the first branch channel and an ink flow rate in the second branch channel while the ink is supplied is smaller than that while the ink flows backward.

摘要： Provided is a sealing member to be used as a valve in a pressure adjustment mechanism. The sealing member includes a base member having high strength, and has high reliability. The sealing member includes an elastic member (valve portion) having an annular abutment portion (valve distal end portion) formed as an annular protrusion and the base member (lever portion). When a held portion having a tubular shape extending from the annular abutment portion is held in an annular groove formed in the base member, the elastic member is fixed to the base member. A holding length over which an annular groove holds the held portion along a depth direction of the base member is set longer than a width of the annular groove.
