PROBLEM TO BE SOLVED: To secure strength of a gas tank without increasing its weight. SOLUTION: In the high-pressure gas tank 2 including a cylindrical body part 2a and a dome part 2b connected to both sides of the body part 2a and tapered off on the end side, an FRP (fiber reinforced plastics) layer 21 consisting of a plurality of layers is formed on the outer circumference face. In a boundary part R between the body part 2a and the dome part 2b, a pin 30 penetrating the FRP layer 21 is arranged. The pin 30 is fixed to an elastic pedestal 31 covering the surface of the FRP layer 21 in the boundary part R. COPYRIGHT: (C)2011,JPO&INPIT |
