PROBLEM TO BE SOLVED: To provide a highly efficient gear pump capable of improving sealability of a connection between a side plate and a seal block, without reference to materials for the side plate and the seal block.SOLUTION: A seal block 6 is formed in a step shape having an inner wall surface 61c for forming a fluid chamber between itself and a tooth space of a gear 4, and a connection JL is provided between the inner wall surface 61c and an outer peripheral surface 7a of a side wall 7. In a high-pressure region HPR on the outside of an annular seal member 81, at least the inner wall surface 61c comprises a connection sealing member 82 that seals the connection JL of a part for forming the fluid chamber.

    【課題】側板とシールブロックの材料に関わらず、側板とシールブロックとの接続部のシール性を向上させることができる高効率なギヤポンプを提供する。【解決手段】シールブロック6は、ギヤ4の歯溝との間に流体室を形成する内壁面61cを有する段差形状に形成されて、該内壁面61cと側板7の外周面7aとの間に接続部JLを有する。環状シール部材81の外側の高圧領域HPRにおいて、少なくとも内壁面61cが流体室を形成する部分の接続部JLをシールする接続部シール部材82を備える。【選択図】図7
