PROBLEM TO BE SOLVED: To provide a vehicular wheel capable of securing the predetermined length of a communicating hole and a cross-sectional area of an opening in a sub air chamber member and enhancing mass productivity. SOLUTION: In this vehicular wheel 10, the sub air chamber member 13 is fixed to the tire air chamber MC side of the wheel. The sub air chamber member 13 formed by processing a hollow pipe includes a sub air chamber SC formed inside both ends of the hollow pipe processed in a collapsing manner; and the communicating hole 13b for making the sub air chamber SC communicate with the tire air chamber MC. The communicating hole 13b is formed at a portion of a point processed in a collapsing manner. On the outside end of the point, one end is opened to the tire air chamber MC, while the other end has a hollow opened to the sub air chamber SC. COPYRIGHT: (C)2008,JPO&INPIT
