。[Claims for Utility Model Registration] (1) A fan-integrated clutch base in which a cooling fan and a base portion supporting a clutch shaft of a centrifugal clutch are integrally formed, and the fan-integrated clutch base has a shaft hole in the center through which the engine crankshaft is inserted. a taper collet that is inserted through the clutch shaft and is fitted into a tapered hole formed at an end of the shaft hole on the side of the cooling fan; and a taper collet that is inserted into the taper hole formed at the end of the shaft hole on the side of the base part. a taper nut screwed onto the tip of the crankshaft; a clutch pilot bearing mounted concentrically on the taper nut; a central shaft rotatably supported by the clutch pilot bearing; and the clutch shaft is rotated by centrifugal force. A power transmission mechanism for a model helicopter, comprising: a clutch drum with which the clutch comes into pressure contact when expanded; and a power transmission member that transmits rotation of the clutch drum to a rotor. (2) The power transmission mechanism for a model helicopter according to claim 1, wherein the taper apex angle of the taper nut is larger than the taper apex angle of the taper collet.
