Each aluminum alloy wheel includes a rim and a disc, and is attached to a hub of an axle by engaging bolt holes on the disc with bolts provided on the hub, and by screwing nuts into the bolts. The disc is made of a single plate, and nut seats are formed around the bolt holes and have a work hardened layer formed thereon. The disc is made of a reduced number of components compared with a wheel of the related art, and does not require any fastening member. Furthermore, no separate nut seats are necessary. This is effective in reducing the number of components and manufacturing cost.

1. A structure of a motor vehicle wheel made of an aluminum alloy, comprising: a rim; a disc attached to said rim, said disc having bolt holes formed therein and being formed from a single stamped plate, said disc including a hub mounting part formed around each of said bolt holes, said hub moun
1. A structure of a motor vehicle wheel made of an aluminum alloy, comprising: a rim; a disc attached to said rim, said disc having bolt holes formed therein and being formed from a single stamped plate, said disc including a hub mounting part formed around each of said bolt holes, said hub mounting part being formed by projections extending away from said bolt holes for engaging with a front surface of a hub of an axle, each of said projections being formed having a surface in the shape of a crescent for engaging with the front surface of the hub; said wheel is attachable to the hub by engaging said bolt holes in the disc with bolts provided on the hub and screwing nuts onto the bolts, or by matching the bolt holes on the disc with internal threads provided on the hub, inserting headed bolts into the bolt holes and screwing the headed bolts into the internal threads; and nut seats or bolt head seats having work hardened layers are provided around the bolt holes. 2. The structure according to claim 1, wherein the disc is provided with weight reduction holes and ornamental holes formed therein. 3. The structure according to claim 2, wherein said weight reduction holes and ornamental holes have chamfered edges. 4. The structure according to claim 2, wherein the nut seats or the bolt head seats are curved. 5. The structure according to claim 4, wherein said curved nut seats or bolt head seats have concave surfaces for receiving cooperating convex surfaces of said nuts or bolts. 6. The structure according to claim 1, wherein said nut seats or the bolt head seats are curved. 7. The structure according to claim 6, wherein said curved nut seats or bolt head seats have concave surfaces for receiving cooperating convex surfaces of said nuts or bolts. 8. The structure according to claim 1, wherein said wheel is formed from only said rim and said disc, and said rim and said disc are each one piece members welded together to form said wheel. 9. The structure according to claim 1, wherein said nut seats or bolt head seats are formed as a single piece with said disc. 10. The structure according to claim 1, wherein only said nut seats or bolt head seats have work hardened layers. 11. A method of making a motor vehicle wheel comprising the steps of: stamping a single plate of aluminum alloy material with a die to form a disc; forming bolt holes in said disc; forming said disc with a hub mounting part around each of said bolt holes, said hub mounting part being formed by projections extending away from said bolt holes, each of said projections having a surface in the shape of a crescent; pressing a punch toward edges of said bolt holes to form a nut or bolt head seat around a periphery of said bolt holes; and forming a work hardened layer on said nut or bolt head seats. 12. The method according to claim 11, further comprising the steps of: forming a rim from a single piece of material; and welding said disc to said rim. 13. The method according to claim 11, further comprising the step of forming weight reduction holes and ornamental holes in said disc. 14. The method according to claim 13, wherein said step of forming weight reduction holes and ornamental holes includes the step of forming chamfered edges around said weight reduction holes and ornamental holes. 15. The method according to claim 11, wherein said step of pressing includes the step of forming said nut seats or bolt head seats curved. 16. The method according to claim 15, wherein said step of pressing includes the step of forming said curved nut seats or bolt head seats having concave surfaces. 17. The method according to claim 11, wherein said step of forming the work hardened layer comprises forming said work hardened layer only on said nut or bolt head seats. 18. The method according to claim 11, wherein said step of forming the work hardened layer comprises pressing a punch to an edge of the bolt holes.
