(57) [Summary] [Constitution] The intrinsic viscosity is 2 to 6 dl / g, the zero shear viscosity at 190 ° C. is 2 × 10 7 to 3 × 10 8 poise, R Value is 2.5 to 4, density is 0.94 to 0.97 g / cm 3. Which has a specific baffle portion and has a minimum wall thickness of the baffle portion in the range of 0.65 to 0.95 with respect to the maximum wall thickness. Fuel tank. [Effects] According to the present invention, it is possible to obtain a light fuel tank having excellent uniform stretchability and excellent impact strength even with a thinner wall thickness than before. |
