Claims

[Scope of utility model registration request]

A telescoping pipe 11 configured to be telescopically operable by an internally provided telescoping mechanism is horizontally hung on a loading platform that also serves as a chassis frame, wheels 10, 10 are attached to both ends of the telescoping pipe 11, and the telescoping pipe 11 is expanded and retracted. A trailer wheel spacing adjustment structure that allows the spacing between left and right wheels 10, 10 to be changed and adjusted by operation.
