LIQUID DISCHARGE HEAD, LIQUID DISCHARGE UNIT, LIQUID DISCHARGE DEVICE, AND INTERMEDIATE MEMBER

To provide a liquid discharge head which enables easy attachment/detachment of an unnecessary member or a necessary member to/from a liquid passage and can easily maintain the passage even if the member is attached or detached.SOLUTION: A liquid discharge head has: a liquid supply part 81; a frame member 82 formed with a passage of a liquid supplied from the liquid supply part; and an intermediate member 83 disposed between the liquid supply part and the frame member. The liquid supply part has a first connection part 91 which may be connected to the frame member. The frame member has a second connection part 92 which may be connected to the liquid supply part. The first connection part and the second connection part may be connected with each other. The intermediate member has: a third connection part 93 having the same shape as the first connection part; and a fourth connection part 94 having the same shape as the second connection part. The first connection part and the fourth connection part may be connected with each other. The second connection part and the third connection part may be connected with each other.SELECTED DRAWING: Figure 1 【課題】液体流路中に不要な部材又は必要な部材を容易に着脱でき、部材を着脱した場合でも流路を容易に維持できる液体吐出ヘッドを提供する。【解決手段】液体供給部８１と、前記液体供給部から供給される液体の流路が形成されたフレーム部材８２と、前記液体供給部と前記フレーム部材との間に配置される中間部材８３とを有する液体吐出ヘッドであって、前記液体供給部は、前記フレーム部材と接続可能な第１の接続部９１を有し、前記フレーム部材は、前記液体供給部と接続可能な第２の接続部９２を有し、前記第１の接続部と前記第２の接続部が接続可能であり、前記中間部材は、前記第１の接続部と形状が同一の第３の接続部９３、及び、前記第２の接続部と形状が同一の第４の接続部９４を有し、前記第１の接続部と前記第４の接続部が接続可能であり、前記第２の接続部と前記第３の接続部が接続可能であることを特徴とする。【選択図】図１
