A weft knitted fabric made from a poly(trimethylene terephthalate) fiber yarn and not containing other elastic yarns such as a polyurethane yarn, a polyester type elastic yarn and a polyester ether type elastic yarn, and showing an elongation under constant load in a range from 80 to 250% in the weft direction under a load of 19.6N per 2.5 cm, an elongation elastic modulus after elongation by 50% of 80% or more in the weft direction, a fabric weight per square meter in a range from 80 to 500 g/m2, a bulk density in a range from 0.28 to 0.60 g/cm3 and a shear rigidity G in a range from 0.28 to 1.50 cN/cm.deg.
