Title:
WHEEL NUT AND MANUFACTURING METHOD FOR THE SAME
Document Type and Number:
Japanese Patent JP2005313874
Kind Code:
A
Abstract:

To provide a wheel nut which does not require a caulking process nor welding process upon attaching a cap, allows free shaping of a flange to some extent, and has improved liquidtightness, and a manufacturing method for the wheel nut.

A tilt angle θ1 between the direction perpendicular to the axis O of a cylindrical part 22 of a cap 20 and a skirt part 23 is made larger than a tilt angle θ2 between the direction perpendicular to the axis O of a hexagonal part 15 of a nut body 10 and a tilted part 12b. When the cylindrical part 22 of the cap 20 is press fitted tightly on the outer peripheral surface of the hexagonal part 15 of the nut body 10, the skirt part 23 deforms elastically as it is pressed by the tilted part 12b of a flange 12, and at least the outer periphery of the skirt part 23 is stuck closely over the tilted part 12b of the flange 12 by an elastic force resulting from the elastic deformation of the skirt part 23.
