Claims

[Claims for Utility Model Registration] 1. A large number of pins extending substantially radially with respect to the mandrel body are arranged at substantially equal intervals in the circumferential direction at both ends of the mandrel body, For filament winding molding used in filament winding molding in which a resin-impregnated roving impregnated with thermosetting resin is wound helically between one pin and the other pin. The pin has a mandrel structure, and the pin is disposed in a pin ring that is removably fitted onto the end of the mandrel body, and the pin is located at an axially innermost part of the joint surface between the pin ring and the mandrel body. The mandrel structure for filament winding molding is characterized by a gap formed for a resin reservoir. 2 At both ends of the mandrel body, a large number of pins extending approximately radially with respect to the mandrel body are arranged at approximately equal intervals in the circumferential direction, and the pins arranged at one end of the mandrel body and the pins at the other end A mandrel structure for filament winding molding used in filament winding molding in which a resin-impregnated roving impregnated with a thermosetting resin is wound helically between a pin disposed in the pin. is disposed on a pin ring that is removably fitted onto the end of the mandrel body, and the pin ring is secured to the mandrel body by a fixing member on the outer side of the pin installation area. A mandrel structure for filament winding molding, characterized in that the pin ring is removably fixed to the pin ring, and a recess for a resin reservoir is formed on the outer periphery of the pin ring between the pin and the fixing member.
