A brake device 20 for braking a hydraulic motor 1, said brake device 20 equipped with a disc plate 21 that rotates together with a cylinder block 3, a brake piston 27 supported on a first case 12, and a brake spring 35, 45 interposed and compressed between the brake piston 27 and a second case 13. The second case 13 has a recessed or protruding retaining part 30, 32, 42 into which one end of the brake spring 35, 45 is inserted, and the brake spring 35, 45 is retained by the retaining part 30, 32, 42 even when the other end of the brake spring is separated from the brake piston 27. L'invention concerne un dispositif de freinage (20) pour freiner un moteur hydraulique (1), ledit dispositif de freinage (20) comprenant une plaque de disque (21) qui tourne conjointement avec un bloc-cylindres (3), un piston de frein (27) monté sur un premier boîtier (12), et un ressort de frein (35, 45) intercalé et comprimé entre le piston de frein (27) et un second boîtier (13). Le second boîtier (13) comprend une partie de retenue évidée ou en saillie (30,32,42) dans laquelle une extrémité du ressort de frein (35, 45) est insérée, le ressort de frein (35, 45) étant retenu par la partie de retenue (30,32,42) même lorsque l'autre extrémité du ressort de frein est séparée du piston de frein (27). 　油圧モータ１を制動するブレーキ装置２０は、シリンダブロック３と共に回転するディスクプレート２１と、第１ケース１２に支持されるブレーキピストン２７と、ブレーキピストン２７と第２ケース１３との間に圧縮して介装されるブレーキスプリング３５，４５と、を備える。第２ケース１３は、ブレーキスプリング３５，４５の一端が差し込まれる窪み状または突起状の保持部３０，３２，４２を有し、ブレーキスプリング３５，４５は、他端がブレーキピストン２７から離れた状態においても、保持部３０，３２，４２によって保持される。
