PURPOSE:To reduce a number of part items and facilitate the work of assembly, by providing an elastic part at least one end of cylindrical portion of the bush material used for knuckle part of connecting rods. CONSTITUTION:To a shaft part 42a of a knuckle shaft 42, secured to a cranking substance 41, is installed a connecting rod 43, and to a flange part 42b side a connecting lever 44, respectively with a clearance. Between the connecting rod 43 and the connecting lever 44, is installed an elastic bush material 40, and this material 40 comorises a cylindrical part 40a, elastic part 40c, 40b engaged to the shaft part 42a of the knuckle shaft 42, and the connecting rod 43 and the connecting lever 44 are rotatable for the knuckle shaft 42. An elastic action of the before said elastic part 40b, 40c restricts a movement of the connecting rod 43 and the connecting lever 44 axially for the knuckle shaft 42, and prevents a looseness of the connecting part, simultaneously provides a relief of deviation like tilt between the knuckle shaft 42 and the connecting rod 43 or connecting lever 44. Accordingly, the function of bush, washer and spring can be combined. |
