| 摘要 |
The invention concerns a craft (10) transportable by road by being hitched at the rear of a vehicle, comprising two wheels (14, 16) capable of being extended from their housing (18) into running position through an opening in the housing (18), each wheel being coupled by a shaft (34) to one first end of a lever arm (32), the assembly being articulated on a shaft integral with the hull (12), and the second end of the lever arm being coupled by a shaft (36) to a shock absorber (38) fixed to a first support (42) for maintaining the wheels (14) in extended position. When the wheels are retracted in the housing, a trap door (50) integral with the lever arm (32) is urged to come to stop on a boss to close the housing (18) opening after the shock absorber has been released and fixed on a second support (52) integral with the lever arm (32) and after the lever arm has been fixed to a third support integral with the hull, so as to close the opening completely, thereby preventing water from penetrating into the housing where the wheel is located.
