a keel, having a fourth through hole parallel to the third through hole; and a second fastening member, wherein, the kingpin passes through the first through hole and the second through hole, and 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 fourth through hole, so as to affix the keel to the truck through the jointing member. ### Claim 6 (depends on 5) The skateboard assembly of claim 5, wherein the third through hole has a diameter greater than a sectional area of the second fastening member. ### Claim 7 (depends on 6) The skateboard assembly of claim 6, wherein the third through hole has a middle part defined by two flat walls that are parallel to each other and separated by a distance equal to or slightly greater than a width of the sectional area of the second fastening member, with two ends of the third through hole each defined by an arc. ### Claim 8 (depends on 5) The skateboard assembly of claim 5, wherein the keel includes at least two lengthwise plates, and each said lengthwise plate has each of two ends thereof formed with the fourth through hole, while the corresponding fourth through holes of the two lengthwise plates are aligned with the third through hole from two sides. ### Claim 9 (depends on 1) The skateboard assembly of claim 1, wherein the pivot of the truck has two first retaining members each deposited between a middle part and an end of the pivot, and the frame has a side that faces the truck and has the pivot hole provided with a first positioning portion, and wherein the skateboard assembly further comprises two second retaining members each having a second positioning portion and a fifth through hole, so that the second positioning portion is engaged with the first positioning portion, and when the pivot passes through the fifth through hole and the pivot hole, the second retaining member is connected to the frame, so that contact between the first retaining member and the second retaining member defines a moving range of the frame. ### Claim 10 (depends on 9) The skateboard assembly of claim 9, wherein the first retaining member is formed with a ramp facing the frame, and the second retaining member has a ramp facing the first retaining member and being parallel to the ramp of the first retaining member. ### Claim 11 (depends on 9) The skateboard assembly of claim 9, wherein the second retaining member is made of nylon. ### Claim 12 (depends on 1) The skateboard assembly of claim 1, wherein the pivot of the truck has two first retaining members each deposited between a middle part and an end of the pivot, and the frame has a side that faces the truck and has the pivot hole provided with a third retaining member, so that when the pivot passes through the pivot hole, contact between the first retaining member and the third retaining member defines a moving range of the frame. ### Claim 13 (depends on 12) The skateboard assembly of claim 12, further comprising a second buffering member, which is deposited between the first retaining member and the second retaining member. ### Claim 14 (depends on 1) The skateboard assembly of claim 1, wherein the first segment or the second segment of the frame has a cutout portion. ### Claim 15 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 jointing member, including a second through hole and a third through hole, wherein the second through hole is parallel to the first through hole, and the third through hole is formed at an end of the jointing member apart from the second through 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. ### Claim 16 (depends on 15) The skateboard of claim 15, wherein the pivot of the truck has two first retaining members each deposited between a middle part and an end of the pivot, and the frame has a side that faces the truck and has the pivot hole provided with a first positioning portion, and wherein the skateboard assembly further comprises two second retaining members each having a second positioning portion and a fifth through hole, so that the second positioning portion is engaged with the first positioning portion, and when the pivot passes through the fifth through hole and the pivot hole, the second retaining member is connected to the frame, so that contact between the first retaining member and the second retaining member defines a moving range of the frame. ### Claim 17 (depends on 16) The skateboard of claim 16, wherein the first retaining member is formed with a ramp facing the frame, and the second retaining member has a ramp facing the first retaining member and being parallel to the ramp of the first retaining member. ### Claim 18 (depends on 15) The skateboard of claim 15, wherein the pivot of the truck has two first retaining members each deposited between a middle part and an end of the pivot, and the frame has a side that faces the truck and has the pivot hole provided with a third retaining member, so that when the pivot passes through the pivot hole, contact between the first retaining member and the third retaining member defines a moving range of the frame. ### Claim 19 (depends on 18) The skateboard of claim 18, further comprising a second buffering member, which is deposited between the first retaining member and the second retaining member. ### Claim 20 (depends on 15) The skateboard of claim 15, wherein the first segment or the second segment of the frame has a cutout portion.
