Claims

[Scope of utility model registration request]

A large number of metal pieces each having a pair of oblique edges that press against the drive belt contact surface formed on the V initial load of the transmission pulley and a belt fitting groove are arranged so as to sequentially form an annular shape in the thickness direction. The endless steel belt is fitted into the continuous belt fitting groove of each metal piece, and the inner circumferential surface of the steel belt is slidably connected to the continuous fitting groove. In the case where an intervening buffer is fitted in the inner part of the groove formed by connecting the circumferential surface and the outer downward circumferential surface and facing the side edge of the endless steel belt,
A drive belt for a belt-driven continuously variable transmission, in which a band-shaped body made of Tanari resin with an oil sump notch is fitted as an intervening buffer into the deep part of the continuous groove.
