Abstract
In a V-belt type transmission having a V-belt entrained on a pulley, the pulley includes a fixed pulley half fixed to an end portion of a crankshaft and a movable pulley half supported on the crankshaft but axially slidable in opposition to the fixed pulley half. The fixed pulley half is secured with a bolt that is threaded and engaged with a female screw formed inside an end portion of the crankshaft. The V-belt type transmission is capable of securely clamping a fixed pulley half and is capable of preventing the entry of dust and water into a fixed pulley half threaded portion formed in an end portion of the crankshaft. This arrangement protects against the formation of rust and corrosion.
