A skateboard includes a board body having a bottom provided with a base having a bottom provided with two opposite wheel seats. Each of the two wheel seats includes a wheel axle for mounting a roller. The wheel axle of each of the two wheel seats has a center located at a height different from that of a center of the respective wheel seat, thereby forming an eccentric state, so that each roller has independent horizontal and vertical displacement, thereby forming a balance effect, so that the skateboard can be moved in a stable manner.

The skateboard in accordance with claim 1, wherein each of the two wheel seats is mounted in the wheel seat receiving portion of the main seat and has a first end and a second end, the first end being formed with a protruding restoring portion movably mounted in the guide channel of the wheel seat receiving portion of the main seat, the restoring portion of each of the two wheel seats has a first side formed with a locking edge that can be moved to abut a wall of the guide channel of the wheel seat receiving portion of the main seat and a second side formed with a resting edge that can be moved to abut the partition of the wheel seat receiving portion of the main seat.3. The skateboard in accordance with claim 2, wherein the second end of each of the two wheel seats is adapted for passage of a respective wheel axle.4. The skateboard in accordance with claim 2, wherein each of the two wheel seat restoring devices includes a restoring member mounted in the receiving channel of the wheel seat receiving portion of the main seat and urged between the partition and a wall of the receiving channel, and an urging seat movably mounted in the receiving channel of the wheel seat receiving portion of the main seat and having a first side formed with a fixing portion fixed on a first end of the restoring member and a second side formed with an urging portion urged on the resting edge of the restoring portion of the respective wheel seat, the urging seat is rested on the partition of the wheel seat receiving portion of the main seat, and the urging portion of the urging seat is extended through the partition of the wheel seat receiving portion of the main seat.5. The skateboard in accordance with claim 4, wherein each of the two wheel seat restoring devices further includes an adjusting seat movably mounted in the receiving channel of the wheel seat receiving portion of the main seat and having a first side formed with a fixing portion fixed on a second end of the restoring member and a second side rested on a wall of the receiving channel of the wheel seat receiving portion of the main seat.6. The skateboard in accordance with claim 5, wherein each of the two wheel seat restoring devices further includes an adjusting screw screwed into the wall of the receiving channel of the wheel seat receiving portion of the main seat and having an end formed with an urging face urged on the second side of the adjusting seat, the second side of the adjusting seat is formed with a depression to receive the urging face of the adjusting screw.7. A skateboard comprising:a board body having a bottom provided with a base; the base having a bottom provided with two opposite wheel seats; a main seat mounted between the base and the two wheel seats; a main seat restoring device mounted between the base and the main seat; two wheel seat restoring devices each mounted between the main seat and a respective one of the two wheel seats; each of the two wheel seats including a wheel axle for mounting a roller; wherein, the wheel axle of each of the two wheel seats has a center located at a height different from that of a center of the respective wheel seat, thereby forming an eccentric state, so that each roller has independent horizontal and vertical displacement, each of the two wheel seats is rotatably mounted on a bottom of the main seat by a wheel seat pivot shaft, and each of the two wheel seats has a mediate portion formed with a shaft passage portion having a center formed with a shaft hole, the wheel seat pivot shaft is extended through the shaft hole of the shaft passage portion of each of the two wheel seats and through the main seat and has two ends each protruding outward from a respective one of the two wheel seats and each threaded thereon with a threaded fixing member so that each of the two wheel seats can be rotated on the main seat about the wheel seat pivot shaft. 8. The skateboard in accordance with claim 7, wherein the wheel axle of each of the two wheel seats is located at a height different from that of the respective wheel seat pivot shaft, thereby forming an eccentric state, so that each roller on the wheel axle has independent horizontal and vertical displacement and has independent buffer displacement.9. A skateboard comprising:a board body having a bottom provided with a base; the base having a bottom provided with two opposite wheel seats; a main seat mounted between the base and the two wheel seats; a base receiving portion formed at the top of the main seat has a first side and a second side; an inverted V-shaped connecting portion rotatably mounted on the base receiving portion of the main seat formed at the bottom of the base, the connecting portion of the base includes: a first side rotatably mounted on the first side of the base receiving portion of the main seat and a second side provided with an urging portion having a distal end formed with a protruding retaining edge; a U-shaped urging portion on the base receiving portion of the main seat provided at the second side of the base receiving portion; a main seat restoring device mounted between the base and the main seat, the main seat restoring device is clamped between the urging portion of the connecting portion of the base and the urging portion of the base receiving portion of the main seat and is retained by the retaining edge, so that the main seat has an automatically restoring function; a base pivot shaft rotatably mounting a top of the main seat to a bottom of the base; and two wheel seat restoring devices each mounted between the main seat and a respective one of the two wheel seats; each of the two wheel seats including a wheel axle for mounting a roller; wherein, the wheel axle of each of the two wheel seats has a center located at a height different from that of a center of the respective wheel seat, thereby forming an eccentric state, so that each roller has independent horizontal and vertical displacement. 10. The skateboard in accordance with claim 9, wherein the first side of the base receiving portion of the main seat is formed with an arcuate guide edge, and the first side of the connecting portion of the base is formed with an arcuate guide edge rested on the guide edge of the base receiving portion.11. The skateboard in accordance with claim 9, wherein the main seat restoring device includes a restoring member made of an elastic block.12. The skateboard in accordance with claim 9, wherein the base pivot shaft is extended through the first side of the connecting portion of the base and the first side of the base receiving portion of the main seat and has a distal end threaded together with a fixing member, so that the main seat can be rotated on the base about the base pivot shaft.13. The skateboard in accordance with claim 12, further comprising a bushing made of wear-resistant material mounted on the base pivot shaft and located between the first side of the connecting portion of the base and the first side of the base receiving portion of the main seat.14. The skateboard in accordance with claim 9, wherein each of the two wheel seats is rotatably mounted on a bottom of the main seat by a wheel seat pivot shaft.15.
