Title:
WHEEL FOR AUTOMOBILE
Document Type and Number:
Japanese Patent JP2010241413
Kind Code:
A
Abstract:

To provide a wheel for an automobile having high durability and fine run-out accuracy, in which difference in rigidity of a disc between positions at which decorative holes are provided in a circumferential direction of the wheel and positions at which spokes are provided in the circumferential direction of the wheel is reduced in comparison with conventional cases.

The wheel 10 for the automobile has a rim 20 and the disc 30. A disc flange 35 of the disc 30 is provided with non-contact sections 36 not making contact with an inner peripheral surface of the rim 20, and the non-contact sections 36 are located on lines each extended from a line passing through the center of each spoke 33 in the width direction, to an outer side of the wheel in the radial direction. As a result, the rigidity of the disc 30 at positions at which the spokes 33 are provided in the circumferential direction of the wheel can be reduced in comparison with the case (conventional case) in which the non-contact sections 36 are not provided. Such a configuration enables the difference in the rigidity of the disc 30 between positions at which the decorative holes 34 are provided in the circumferential direction of the wheel and positions at which the spokes 33 are provided in the circumferential direction of the wheel to be reduced in comparison with the conventional case. As a result, the wheel 10 can have the increased durability and improved run-out accuracy in comparison with the conventional case.
