。 A pair of fixed conical wheels and a movable conical wheel capable of holding a transmission V-belt are provided, and the fixed conical wheel includes a cylindrical fixed boss portion, a fixed conical portion connected to one end of the fixed boss portion, and a pair of movable conical wheels capable of holding the transmission V-belt. The movable conical wheel has a cylindrical movable boss part that is slidably fitted inside the fixed boss part, and a cylindrical movable boss part that is slidably fitted inside the fixed boss part. a movable cone part connected to one end of the boss part and facing the fixed cone part, and a sleeve slidable relative to the movable boss part is fitted inside the movable boss part. one end of the sleeve is fixed to the inward flange of the fixed conical wheel, and the sleeve is provided between the fixed conical wheel and the movable conical wheel to urge the movable conical wheel toward the fixed conical wheel. A spring member is interposed, and a tapered portion is formed on the inner surface of the sleeve, and the tapered portion widens from an end near the inward flange of the fixed conical wheel to an opposite end. Further, an adapter is fitted inside the sleeve, and the adapter has a tapered part on the outer surface that matches the tapered part of the sleeve and is removably fixed to the end of the transmission shaft. A tension bolt is screwed into a screw hole at the end of the fixed conical wheel near the inward flange,
In a belt-type continuously variable transmission, the head of the tension bolt is engaged with an end of the sleeve closer to the inward flange of the fixed conical wheel. A belt type continuously variable transmission characterized in that the diameter of the inner through hole is smaller than the outer diameter of the head of the tension bolt.
