Abstract
A cap member is for covering, during suction operations, nozzle rows formed in a single nozzle plate of an ink jet head on an ink jet printer. The cap member includes a surrounding lip, a partitioning lip, and a body. The surrounding lip is for forming a sealed condition around the nozzle rows when in intimate contact with the nozzle plate during suction operations. The partitioning lip is for forming, with the outer lip portion, partitioned spaces that separate the nozzle rows from each other. The body is formed from resin and includes an integral base portion and protruding portion. The base portion is formed with a separate suction hole for each partitioned space. The protruding portion protrudes away from the base portion. At least one of the surrounding lip and the partitioning lip cover the protruding portion.
