Abstract
Disclosed is an improved friction type of power transmission mechanism for driving a reel support in a VTR wherein the power is transmitted from the motor to the reel support via the follower pulley, which is sandwiched and clamped between a base disk and an annular plate. The follower pulley has a first friction ring sandwiched between the base disk and the lower flange surface of the follower pulley and a second friction ring sandwiched between the annular plate and the upper flange surface of the follower pulley. With this arrangement an increased torque can be produced without causing excessive abrasion. The diameter of the circular opening of one of the first and second friction rings is equal to or larger than the outer diameter of the other friction ring. This has the effect of saving the material of friction ring.
