A roller skate frame includes a wheel-mounting plate for mounting wheels thereon, a shoe-mounting plate projecting transversely from a top end of the wheel-mounting plate and disposed at one side of the wheel-mounting plate that is opposite to the wheels, a plurality of wheel-mounting protrusions projecting from the wheel-mounting plate, and a plurality of reinforcing ribs, each of which projects transversely from a bottom end of the wheel-mounting plate and interconnects two adjacent ones of the protrusions.

1. A roller skate frame comprising:a wheel-mounting plate having top and bottom ends, said wheel-mounting plate being formed with a plurality of first through-holes adjacent to said bottom end, each of said first through-holes extending in a transverse direction relative to said wheel-mounting plate

1. A roller skate frame comprising:a wheel-mounting plate having top and bottom ends, said wheel-mounting plate being formed with a plurality of first through-holes adjacent to said bottom end, each of said first through-holes extending in a transverse direction relative to said wheel-mounting plate;a shoe-mounting plate adapted to receive an article of footwear thereon, projecting in said transverse direction from said top end of said wheel-mounting plate, and disposed at one side of said wheel-mounting plate that is adapted to be opposite to a wheel;a plurality of spaced apart wheel-mounting protrusions, each of which projects from a periphery of a respective one of said first through-holes in said transverse direction, each of which is disposed at said side of said wheel-mounting plate, and each of which defines a second through-hole that extends from a respective one of said first through-holes in said transverse direction; anda plurality of first reinforcing ribs, each of which projects from said bottom end of said wheel-mounting plate in said transverse direction and extends between and interconnects two adjacent ones of said protrusions. 2. The roller skate frame of claim 1, wherein each of said first through-holes defines a first axis, said second through-hole in each of said wheel-mounting protrusions defining a second axis that is parallel to and that is offset from said first axis, said second through-hole in each of said wheel-mounting protrusions eccentrically extending and being reduced from the respective one of said first through-holes in said transverse direction. 3. The roller skate frame of claim 1, wherein said wheel-mounting plate and said shoe-mounting plate form an acute angle, and said wheel-mounting plate is elastically movable relative to said shoe-mounting plate in such a manner that said acute angle varies in an extent corresponding to an external force applied to the wheel by the ground so as to maintain constant alignment of the wheel relative to said wheel-mounting plate. 4. The roller skate frame of claim 3, further comprising a plurality of second reinforcing ribs, each of which extends between and interconnects two adjacent ones of said protrusions and is spaced apart from and parallel to a respective one of said first reinforcing ribs. 5. The roller skate frame of claim 4, wherein said shoe-mounting plate includes a front plate and a rear plate that is spaced apart from and that is disposed rearwardly of said front plate, said roller skate frame further comprising a generally U-shaped bridging plate that projects from said top end of said wheel-mounting plate in said transverse direction and that extends between and that interconnects said front and rear plates. 6. The roller skate frame of claim 5, wherein said bridging plate has a rear end connected to said rear plate of said shoe-mounting plate, said roller skate frame further comprising a third reinforcing rib that extends between and that interconnects a front most one of said protrusions and said rear end of said bridging plate. 7. The roller skate frame of claim 1, wherein said shoe-mounting plate, said wheel-mounting plate, said protrusions, and said first reinforcing ribs are integrally formed by molding a carbon fiber reinforced resin material to form a molded body that has a structure corresponding to that of said roller skate frame, followed by machining and trimming said molded body. 8. The roller skate frame of claim 1, wherein said shoe-mounting plate, said wheel-mounting plate, said protrusions, and said first reinforcing ribs are integrally formed by forging a metal body to form a forged body that has a structure corresponding to that of said roller skate frame, followed by machining and trimming said forged body.
