A truck (20) journaling a wheel (W) is turnably supported leftward and rightward from a neutral position and, at the same time, a support (1) for returnably urging the truck (20) to the neutral position is provided. The support (1) comprises a weighting table (2) fixed to a deck (D) and a support table which is pivotally connected to this weighting table (2) and detachably and attachably fixes the truck. A link piece (7) is pivotally connected between the weighting table 2 and the support table (10) and, when the support table (20) is turned leftward and rightward from the neutral position, the support table (10) is allowed to return to the neutral position due to a repulsive force of a coil spring (S).

1. A truck structure of a skateboard comprising:a truck for supporting a wheel;a support for turnably supporting the truck leftward and rightward from a neutral position and returnably urging the truck to the neutral position,wherein the support comprises a weighting table fixed to a deck of the skateboard and a support table which is pivotally connected to this weighting table and turnable leftward and rightward; said support table being detachably and attachably fixed to said truck, anda link piece being pivotally connected between the weighting table and the support table and, when said support table turns leftward and rightward from the neutral position, the support table is returned to the neutral position by a repulsive force of an elastic member compressed by the link piece.2. The truck structure of the skateboard according to claim 1, further comprising:a cap-shaped pedestal portion having a base portion, the weighting table protruding cylindrically therefrom, said support table having the same concentric diameter as said base portion and is pivotally and movably engaged with the base portion; anda fixture portion which extends from a bottom face of the base portion to one side and detachably and attachably mounts the truck,wherein said base portion is externally engaged with the pedestal portion, and the fixture portion is pivotally connected along an axis line of said base portion.3. The truck structure of the skateboard according to claim 2, further comprising:a storage portion provided on a bottom face side of the fixture portion of the support table and storing a coil spring as the elastic member;an adjustment bolt, which extends by penetrating a hollow of the coil spring, being screwed on a peripheral wall of said storage portion; anda nut which pushingly abuts against an end portion of and being moveable back and forth on the adjustment bolt.4. The truck structure of the skateboard according to claim 3,wherein the link piece comprises an L-shaped plate piece, and a base end side of the plate is screwed on a protrusion fixed on a bottom side of said base portion, and a top end side screwed on the adjustment bolt of said plate is positioned within said storage portion and receives said adjustment screw therethrough within said storage portion and, at the same time, said top end side pushingly abutting against a rear end side of the coil spring,wherein said protrusion is arranged on an axis line of the adjustment bolt at the neutral position and, when the support table is rotated, the protrusion moves away from said axis line, and the coil spring is repulsively compressed by the link piece.5. The truck structure of the skateboard according to claim 1, wherein the truck comprises a hanger journaling a wheel, and a main body portion having a pivot fixed to a pedestal portion having a pivot hole by a king pin trough bush rubbers.6. The truck structure of the skateboard according to claim 1, wherein the pedestal portion of the truck is fixed to one side of the deck of the skateboard and is made as a fixed wheel, and the support is fixed to the other side of the deck, and the truck is detachably and attachably fixed on the support so as to make it as a rudder wheel.
