A skateboard comprising:

• a truck, including a pivot that has two oppositely extending axial sections;
• two frames, each of the frames including a pivot hole, and a first segment and a second segment extending at two sides of the pivot hole, wherein the first segment and the second segment include an angle and each of the first and second segments has an end apart from the pivot hole provided with an axle, wherein the two frames are rotatably mounted to the two oppositely extending axial sections respectively, and are pivoted independently;
• wheels, each rotatably mounted around the axle of the first segment and of the second segment;
• a baseplate that includes a first mounting hole;
• a kingpin that extends from one side of the baseplate;
• a first buffering member, which is mounted around the kingpin, wherein the kingpin has a sectional area smaller than a diameter of the first through hole, and the first buffering member is at least partially received in a gap formed between the kingpin and the first through hole;
• a first fastening member;
• a second fastening member;
• a deck, including a second mounting hole correspond to the first mounting hole;

• a keel, having a fourth through hole parallel to the third through hole;
• and
• a third fastening member,
• wherein, the kingpin passes through the first through hole and the second through hole and gets engaged with the first fastening member so as to fixedly combine the truck with the baseplate, and the third fastening member passes through the first mounting hole and the corresponding second mounting hole, so as to fixedly combine the baseplate with the deck,
• wherein, the jointing member is fixed to the truck through the first fastening member, and wherein the second fastening member passes through the third through hole and the corresponding fourth through hole, so as to affix the keel to the truck through the jointing member.
