An adjustable V-belt pulley comprising a first molded glass bead reinforced plastic member having a hub part with a central through aperture and a first annular flange part intermediate the ends of the hub part. One end of the hub part of the first member is externally threaded and has two external radial slots therein spaced one hundred and eighty degrees (180.degree.) apart and the side of the flange adjacent thereto is tapered outwardly in the direction away from the threaded hub part. The hub part at the other side of the flange part is split and provided with aligned apertures for the reception of a bolt for clamping the first member upon a shaft.
