A wheel assembly for a skateboard includes a positioning seat, a wheel set and an adjustment seat mounted respectively on bottom and top sides of the positioning seat, a positioning post, and a pair of opposite resilient plates, each having fixed and abutting ends. The adjustment seat includes first and second portions, and a receiving space. The first portion and the positioning seat are interconnected pivotally so as to permit relative movement between the positioning and adjustment seats. The positioning post extends into the receiving space. The resilient plates are disposed in the receiving space on opposite sides of the positioning post. The abutting ends of the resilient plates abut against the positioning post.

I claim: 1. A wheel assembly for a skateboard, comprising: a positioning seat having a top side and a bottom side; a wheel set mounted on the bottom side of said positioning seat; an adjustment seat mounted on the top side of said positioning seat, said adjustment seat including a first portion, a second portion opposite to said first portion, and a receiving space, said first portion and said positioning seat being interconnected pivotally so as to permit relative movement between said positioning seat and said adjustment seat; a positioning post mounted on said positioning seat and extending into said receiving space; and a pair of opposite resilient plates positioned on said adjustment seat within said receiving space and disposed on opposite sides of said positioning post, each of said resilient plates having a fixed end disposed proximate to said second portion, and an abutting end opposite to said fixed end, said abutting ends of said resilient plates abutting against said positioning post. 2. The wheel assembly as claimed in claim 1, further comprising a resiliency adjustment device mounted on said adjustment seat for adjusting resiliency of said resilient plates. 3. The wheel assembly as claimed in claim 2, wherein said resiliency adjustment device includes an adjustable piece mounted slidably on said resilient plates between said fixed ends and said abutting ends, said adjustable piece being formed with two grooves for inserting said resilient plates respectively therethrough, said adjustable piece being movable toward and away from said fixed ends so as to adjust resiliency of said resilient plates. 4. The wheel assembly as claimed in claim 3, wherein said resiliency adjustment device further includes a screw rod extending into said receiving space through said second portion of said adjustment seat and located between said resilient plates, said screw rod extending threadedly through said adjustable piece so as to permit adjusting of said adjustable piece. 5. The wheel assembly as claimed in claim 4, wherein said screw rod has one end located externally of said second portion of said adjustment seat, said one end being provided with an adjustment knob for rotating said screw rod. 6. The wheel assembly as claimed in claim 4, wherein said resiliency adjustment device further includes a first vertical post that is mounted within said receiving space, that is sleeved on said screw rod, and that is located between said adjustable piece and said positioning post, and a spring member sleeved on said screw rod and having two ends abutting respectively against said adjustable piece and said first vertical post. 7. The wheel assembly as claimed in claim 6, wherein said resiliency adjustment device further includes a C-shaped ring sleeved on said screw rod so as to clamp said screw rod. 8. The wheel assembly as claimed in claim 6, wherein said resiliency adjustment device further includes a second vertical post sleeved on said screw rod opposite to said first vertical post, said second vertical post cooperating with said second portion of said adjustment seat to fix said fixed ends of said resilient plates on said adjustment seat. 9. The wheel assembly as claimed in claim 1, further comprising a spindle for connecting pivotally said first portion of said adjustment seat to said positioning seat. 10. The wheel assembly as claimed in claim 1, wherein said abutting ends of said resilient plates are curved ends.
