PROBLEM TO BE SOLVED: To accurately position/support the peripheral edge part of a fixed side disk without machining the inner peripheral surface of a casing body. SOLUTION: In this tractor with a multi-disk brake device, a rotating side disk integrally rotating with an output shaft is fitted to the outer peripheral surface of the output shaft. A fixed side disk is disposed near the rotating side disk in a fixed state, and both disks are brought into surface contact with each other in a pressed state by a pressingly acting body to brake the rotation of the output shaft. A plurality of disk support pieces are disposed around the output shaft disposed in the casing body, and the peripheral edge part of the fixed side disk is positioned/supported by these disk support pieces to dispose the fixed side disk around the output shaft in the fixed state.
