ABSTRACT:
A truck includes a chassis attached to a deck of the skateboard, a yoke pivotally connected to the chassis and two wheels provided on the yoke. The chassis includes a rod extended from the underside thereof. The yoke includes a first portion, a second portion extended from the first portion, a third portion extended from the second portion so that the first and third portions thereof are biased and a rod extended from the upside of the first portion thereof. The wheels are provided on third portion of the yoke. A torque spring includes two ends located on opposite sides of the rods. One of the ends of the torque spring engages with the rod of the chassis while the remaining end of the torque spring engages with the rod of the yoke. Thus, the torque spring is loaded and tends to return the yoke relative to the chassis.
