された状態にて回転可能に支持されている。However, with this structure, the total length of the drive device and the drum becomes long, and if there is a limited space such as a car body, the length occupied by the drum is shortened, which inevitably reduces the capacity of the drum. It was hot. In order to solve the above-mentioned drawbacks, the present invention incorporates a hydraulic motor in an inner cylinder that is a part of the speed reducer, and also incorporates a part of the speed reducer in the recess of the front wall of the drum, so that it can be used in a limited space. This allows the drum to occupy a longer length. The embodiment will be explained below with reference to the drawings. 1 is a drum mounted on the vehicle body 2, and the core drum 1' can be rotated in a tilted state downward forward by the front strut 3 and the rear strut 4. is supported by

ることができる。The present invention has the above-described structure. Next, I will explain the operation. When rotating the drum, first the hydraulic motor 6 is activated, and the rotation of the drive shaft 17 is decelerated by the deceleration mechanism 19. When the outer ring 15 is rotated, the drum integrated with the outer ring 15 is also rotated together. At this time, the vehicle body may vibrate due to driving, etc., and the drum may swing vertically and horizontally. Since it can swing while being supported by the portion 11, the drum 1 can be rotated automatically without interfering with the rotation of the drum 1. As described above, in the present invention, the hydraulic motor is housed inside the reduction gear, and a part of the reduction gear is also housed in the recessed part of the front wall of the drum, so that the entire drive apparatus becomes very compact, and it can be used in a limited space such as the vehicle body. The drum occupies a longer space in a longer space, and the storage capacity of the drum can be increased.
