In this paper the effect of grain size on the shear characteristics of granular materials is studied from the results of drained triaxial compression tests. The materials tested are Shirasu, Coral ahd Coal having different shape and surface texture. Deviator stress, angle of shearing resistance, volume changes, dilatancy factor and energy components at failure are mainly examined. In the examination it is clarified that they generally increase with a decrease in grain size, and that as the shape and surface texture become unusual, the effect of grain size on them increases. As volume changes and dilatancy factor at failure increase with a decrease in gain size, in all materials the critical void ratios, which are determined by (⊿V／Vo)f＝O method and (dV／Vε1)f＝O method, increase correspondingly with a decrease in grain size. And in all materilas of each grain size the critical void ratio determined by（dV／Vε1）f＝O method is larger than that by(⊿V／Vo)f=O method.
