PROBLEM TO BE SOLVED: To provide a high efficiency gear pump and a brake device using the same.SOLUTION: A gear pump 1 comprises: a pair of gears 4 engaged with each other; a seal block 6 and a side plate 7 including slide contact surfaces 6s and 7s in slidable contact with side surfaces of the paired gears 4 while holding the gears 4 therebetween in a rotary axis direction; and a case 15 accommodating the gears 4, the seal block 6, and the side plate 7, a region around the seal block 6 and the side plate 7 being defined as a discharge-side high-pressure region HR. A deformation allowable chamber 26 is provided between the case 15 and the seal block 6 on an opposite side to the slide contact surface 6s of the seal block 6.

    【課題】高効率のギヤポンプと、それを用いたブレーキ装置を提供する。【解決手段】ギヤポンプ1は、互いに噛み合う一対のギヤ4,4と、該一対のギヤ4,4を回転軸方向に挟持してギヤ4,4の側面に摺接する摺接面6s,7sを有するシールブロック6および側板7と、これらを収容するケース15とを備え、シールブロック6および側板7の周囲が吐出側の高圧領域HRとされている。シールブロック6の摺接面6sと反対側でケース15とシールブロック6との間に変形許容室26が設けられている。【選択図】図8
