Abstract

PURPOSE: To reduce the total weight of the mast with the required strength being secured, by forming the mast with carbon fiber reinforced plastics, and providing a protecting material at a mast mounting hole part.
CONSTITUTION: The mast 3 is formed by carbon fiber reinforced plastics, and a reinforcing ring 8 made of aluminum and the like is bonded to the position corresponding to the upper end of the mast mounting hole 11. A protrusion 80 for hooking rope can be provided on the reinforcing ring 8. Since the mast is formed by said carbon fiber reinforced plastics, the upper part thereof can be tapered, and the weight can be reduced. Since the reinforcing ring is used at the location where the largest stress is applied, the required strength can be secured.
