PROBLEM TO BE SOLVED: To provide a motor with a speed reducer which is equipped with a coupling structure between a fixed case of a hydraulic motor and a carrier of a speed reducing mechanism capable of sufficiently ensuring coupling force, and having excellent workability.SOLUTION: A hydraulic motor 1 with a speed reducer includes: a fixed case 4 in which a hydraulic motor mechanism 5 is disposed inside, and formed with a case side groove 45 on which a peripheral surface of a fixing pin 51 abuts on an outer peripheral surface; and a speed reducing mechanism 7 coupled to an output shaft 13 of the hydraulic motor mechanism 5. The speed reducing mechanism 7 has a second carrier 29 formed with a carrier side groove 43 on which the peripheral surface of the fixing pin 51 abuts on an inner peripheral surface of a collar portion 41. While the fixed case 4 and the second carrier 29 are superimposed, a hole 52 reaching a part of the fixed case 4 is bored on the carrier 29 from the opposite side to the fixed case 4, thereby forming the case side groove 45 and the carrier side groove 43 by simultaneous machining. |
