The apparatus is mounted on the end of a pulley of the V-belt drive and is comprised of a tapered member connected to the output shaft of the power source for engaging in holding relationship the pulley of said V-belt drive; a retractor member attached to the pulley; and a toggle linkage for displacing the retractor member relative to the tapered member to disengage the pulley from the tapered member. The toggle linkage includes a first pair of diverging toggle links and a second pair of crossing toggle links having end portions pivotally connected to end portions of said first pair of toggle links. The second pair of toggle links is mounted in a sleeve for rotation about an axis having a fixed relationship to the tapered member.
