PROBLEM TO BE SOLVED: To provide a power transmission mechanism that is easily assembled, only needs small members, and has elastic bodies (such as rubber) and excellent buffer action and durability of the component members. SOLUTION: Six axially projected sections (ring pieces radially divided and cut in one twelfth) 24a are placed on the same diameter line of inner circumference of a pulley 24 at a constant interval. Between the respective adjoining axially projected sections, rubber blocks 25 are inserted respectively. The respective rubber block 25 is constituted in a shape of the ring pieces radially divided and cut in one twelfth, and cutouts 25a with an approximate T-shape in section are formed from the inner circumferential surface to the outer circumferential surface. Six axially projected sections 26 with an approximate T-shape in section are formed on the same diameter line of inner surface of a torque transfer plate 26 with a constant interval. The cutouts of the respective rubber blocks are respectively engaged into the respective axially projected sections of the torque transfer plate. When the respective rubber blocks are inserted between the respective adjoining axially projected sections of the pulley, respective protrusions 25b of the respective rubber blocks are fitted into respective recesses 24a<SB>2</SB>of the respective axially projected sections.
