A transmission belt that is to be mounted on pulleys, for transmitting a force between the pulleys. The transmission belt includes: at least one endless annular hoop; and plate-shaped elements that are held by the at least hoop such that the elements are arranged in a circumferential direction of the transmission belt. The elements, each of which has a pair of flank surfaces at its widthwise opposite ends, are to be clamped between conical surfaces of a substantially V-shaped annular groove of each of the pulleys. A flank angle of each of the flank surfaces is larger than a cone-generating angle of each of the conical surfaces. The elements include first and second elements, such that each of the first elements is to be in contact at the flank surfaces with the conical surfaces, and has a width larger than a width of each of the second elements.

Transmission belt

A stationary pulley () includes a pressing pulley () having a stationary pulley surface () and also includes a support pulley () having a rotating shaft () fixed to the center section of the support pulley. The support pulley () is placed so as to face a movable pulley surface () across the pressing pulley () in the direction of the axis of the rotating shaft (), and the support pulley () supports an outer peripheral section () of the pressing pulley () so as to restrain axial movement of the outer peripheral section (). The pressing pulley () has an inner peripheral section () axially movable relative to the rotating shaft () and can transmit torque to the rotating shaft ().
