The invention relates to a scroll-type compressor which will not exert an undesirable influence on a power source of a rotation shaft, even if seizing occurs between an orbiting scroll member and a fixed scroll member. A power transmission mechanism P is provided between a rotation shaft,and an eccentric drive pin,for transmitting power to an orbiting scroll member,. An inner wall of a bore of a closed ended cylindrical member,with an eccentric drive pin,protruding from a base end thereof is formed in the height direction of the cylinder with a plurality of grooves,of semi-circular cross-section. Moreover, a cylindrical resilient roller,is centrally provided on the closed end with a height approximately the same as that of the closed ended cylindrical member,. Rollers,are provided so as to be inscribed in each groove,and so as to come into contact with an outer peripheral surface of the resilient roller,. Projections,provided on the rotation shaft,are insertingly fitted so as to fill the spaces between the rollers
