Abstract
A skateboard includes a board adapted for a user to stand with both feet thereon and having a major axis, and a front steering device and a rear steering device respectively disposed on front and rear sections of a bottom surface of the board along the major axis and each having two wheels. The front or rear steering device has a wheel seat disposed on the bottom surface of the board rotatably around a rotation axis which inclines downwards from front to rear, and a wheel rack disposed on the wheel seat rotatably or swingably around a main axis. An abutted surface is defined where the wheel seat and the wheel rack are abutted against each other. On an imaginary vertical plane including the major axis, where the rotation axis passes the abutted surface is in front of where the main axis passes the abutted surface.
