Document Type and Number:
Japanese Patent JP2017177957
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a disc wheel having a heat radiation structure which can efficiently discharge heat in the disc wheel to the outside by a simple constitution.SOLUTION: A disc wheel 10 having a disc part 10d and a rim part 70 comprises an intake port 10i, an exhaust port 10o and an agitation plate 15. The intake port 10i is formed at an external peripheral side of the disc part 10d, and takes outside air at the outside of the disc part 10d into the disc part 10d. The exhaust port 10o is formed at an internal peripheral side of the disc part 10d rather than the intake port 10i, and discharges inside air at the inside of the disc part 10d to the outside of the disc part 10d. The agitation plate 15 is protruded into the disc part 10d, agitates the inside air, and guides it to the intake port 10i. The intake port 10i is formed so that an inside opening which faces the inside air becomes narrower than an outside opening which faces the outside air, and the exhaust port 10o is formed so that the outside opening which faces the outside air intake becomes narrower than the inside opening which faces the inside air.SELECTED DRAWING: Figure 1
