PROBLEM TO BE SOLVED: To provide a gear pump capable of properly keeping pressing force between a side plate and a gear even at high-temperature, and a brake device.SOLUTION: A seal device 70 is provided, which is disposed in a storing portion 62a formed on a housing 52 or a side plate 62 with an interference in a direction separating the housing 52 and the side plate 62 between the housing 52 and the side plate 62, and divides a high-pressure portion 80a and a low-pressure portion 80b formed in a radial direction of gears 58 and 60. The interference corresponding to the radial direction of the gears 58 and 60 is set to be larger than the interference corresponding to a thrust direction of the gears 58 and 60.

    【課題】高温時においても側板とギヤとの間の押圧力を適切に保つことができるギヤポンプおよびブレーキ装置を提供すること。【解決手段】ハウジング52と側板62との間にハウジング52と側板62を離間する方向の締め代をもってハウジング52または側板62に形成された収容部62aに配置され、ギヤ58、60のラジアル方向に形成される高圧部80aと低圧部80bとを区画するシール装置70を備え、締め代をギヤ58、60のラジアル方向に対応する締め代がギヤ58、60のスラスト方向に対応する締め代より大きく設定するようにした。【選択図】図2
