PROBLEM TO BE SOLVED: To provide a handcart capable of expanding flexibility without receiving a restriction on design, and finely keeping a balance during walking by coupling a front wheel leg portion and a rear wheel leg portion to an optional position of each handle strut portion.SOLUTION: On right and left handle strut portions 18 supporting a handle from a lower side, small-diameter cylinder portions 23 extending downward from both ends of the handle, and large-diameter cylinder portions 24 in which the small-diameter cylinder portions 23 are slidably inserted, are provided. The small-diameter cylinder portion 23 is formed to have a true-circular cross section, and on the other hand, the large-diameter cylinder portion 24 is formed to have a generally track-shaped cross section, and a sliding guiding path 242 for sliding/guiding the small-diameter cylinder portion 23 and a storage space 243 are respectively provided on one side and the other side in a long-diameter direction of the large-diameter cylinder portion 24. In the storage space 243, a rivet portion 272 in which a tip end of a blind rivet 27 is inserted from the outside and plastically deformed by swaging is stored so as to avoid an interference with each small-diameter cylinder portion 23 inserted in the sliding guiding path 242.SELECTED DRAWING: Figure 5 |
