PROBLEM TO BE SOLVED: To provide a boat carrier which can be reciprocated in a stable condition without transferring an incline to a different appliance, and travel without selecting any traveling surface. SOLUTION: Upper end parts of column parts 1a of a portal frame 1A provided in the longitudinal advancing/retracting direction with a predetermined interval therebetween are pivotably supported by a beam part 1b and lower end parts of the column parts 1a are pivotably supported by a crawler type traveling unit 5, and a boat B is stored therein and travels on an inclined passage. An angle of the portal frame 1A with respect to the crawler type traveling unit 5 is adjusted by an inclination adjusting mechanism (a hydraulic cylinder device 2), and the center of gravity of a boat carrier 1 storing the boat B is moved in a stable state. The crawler type traveling unit 5 can continuously travel on the incline irrespective of any traveling surface. COPYRIGHT: (C)2004,JPO
