PROBLEM TO BE SOLVED: To use a power assisted drive wheel and a hand-pushed truck by connecting or disconnecting them as necessary to lighten carrying work and reduce a system cost. SOLUTION: In structure of a truck connecting arm part 1 of the power assisted drive wheel generating a driving force corresponding to human power, an upper surface part of a truck connection plate corresponding to a truck side upper part connecting pin position is cut out to constitute tapered structure, and a connecting rod 3 moving up and down by a lever operation in the inside of a lower surface of the truck connection plate is provided. On the other hand, a bolt-shaped connecting pin is disposed to an upper part of a truck-side connecting plate corresponding to a connecting/fitting position at the truck connecting part of the power assisted drive wheel mechanism. In the lower part, sliding guides sliding a connecting plate upward and downward and a support rail supporting them are fixed and installed to the truck. The connecting plate is provided with an L-shaped hook for catching the connecting rod disposed at a drive-wheel-side lower part connecting position. COPYRIGHT: (C)2009,JPO&INPIT
