Abstract

PURPOSE:To reduce stress generated at a wind hole portion and to improve fatigue strength by decreasing the wall thickness in the periphery of the wind hole formed on a disc to be wedge-shaped in section, and setting the decreased wall portion in such a manner as to satisfy specified dimensional relationship. CONSTITUTION:A wheel comprises a rim for holding a tire and a disc to which a hub is fitted. A wind hole 20 or the like is formed on a disc raw material 20. In this case, the disc raw material 20 has a wall thickness in the periphery of the wind hole 21 decreased to form a wedge-shaped section, and the decreased wall portion is set in such a manner as to satisfy the following conditions. That is, when half the shortest distance between the adjacent wind holes 21 is supposedly l0, the width of the decreased wall portion l1, the wall thickness of the disc raw material 20 h0 and the wall thickness of the end portion of the wind hole 21 h1, for example, if l1/l0<=0.1, it is set to satisfy the condition that -9.5(l1/l0)+1.275<=(h1/h0<=-0.510(l1/l0)<2>+0.95.
