Claims

[Scope of utility model registration request]

(1) Both ends of the fixed shaft are fixedly supported by a pair of supports, and roller supports are rotatably supported by a pair of bearings fitted on both ends of the fixed shaft, and the rollers are mounted inside these roller supports. An electric motor that is fitted and fixed at both ends of the circumferential part, has a stator part installed at the center in the axial direction of the fixed shaft, and a rotor part corresponding to the stator part and mounted on the same circumferential part of the roller. In the built-in roller device, a fan is attached to the rotating part on the roller side, and the fan sucks in external cooling air from one end side in the axial direction of the roller, and passes it through the electric motor inside the roller to the other side. A roller device with a built-in electric motor that discharges from the end side.

(2) The roller device with a built-in electric motor according to claim 1, which is a registered utility model, characterized in that each end of the fixed shaft is provided with ventilation holes that open to the outside and communicate with the inside.

(3) Utility model registration claim 1, which is characterized in that the roller support is provided with ventilation holes that communicate the outside and the inside.
Roller device with a built-in electric motor as described in .

(4) A utility model registration request characterized in that each end of the fixed shaft is provided with ventilation holes that open to the outside and communicate with the inside, and furthermore, the roller support is provided with ventilation holes that communicate with the outside and the inside. A roller device with a built-in electric motor according to Scope 1.

(5) The roller device with a built-in electric motor according to any one of claims 1 to 4, wherein the fan is an axial fan.

(6) A roller device with a built-in electric motor as set forth in any one of claims 1 to 5 of the utility model registration claim, characterized in that a fan is mounted on the inner circumference of the roller at a position closer to the rotor.

(7) A roller device with a built-in electric motor according to any one of claims 1 to 5 of the utility model registration claim, characterized in that a fan is attached to the end side of the roller.

(8) A roller device with a built-in electric motor according to any one of claims 1 to 5 of the registered utility model claim, characterized in that a fan is attached to a roller support.
