A transmission belt includes a belt body, two spaced-apart mounting axles and a reinforcing unit. The belt body forms a loop that defines an inner space. The mounting axles and the reinforcing unit are embedded in the belt body. The reinforcing unit includes at least one cord that includes a plurality of winding segments and a plurality of connecting segments. The winding segments alternately extend around the mounting axles. Each of the connecting segments interconnects a corresponding pair of the winding segments that respectively extend around the mounting axles.

A continuously variable transmission includes a primary pulley, a secondary pulley, a metal belt and a controller. The metal ring includes a ring and a plurality of elements bundled by the ring. The elements have respective receiving portions opening in a radial direction of the metal belt and receive the ring in the receiving portions. Assuming a direction perpendicular to a circumferential direction and a radial direction of the metal belt as a lateral direction L, the controller executes a falling-off countermeasure control of the element when a relative movement of the element in the lateral direction L with respect to the ring is detected or a presence of an action of a force on the element which causes such relative movement is detected.

An element of a transmission including: a rocking edge portion with a convex surface formed on one of a front face and a rear face, so that the rocking edge portion extends over a pillar portion at least partially, the rocking edge portion having a contact line where the adjacent elements contact each other serves as a fulcrum of rotation of the adjacent elements; and a recessed non-contact portion extends along the saddle surface, to avoid contact with the adjacent element, and that divides the rocking edge portion in the width direction at least partially. A depth of the non-contact portion is set so that an end portion of the non-contact portion is positioned on an inner peripheral side of the transmission belt relative to the contact line when a winding radius is minimized, and the end portion does not reach the trunk portion on the inner peripheral side.

A metal element, which is pressed and punched by a mold, includes: a neck section positioned between a pair of right and left ring slots; an ear section continuous to a radially outer side of the neck section; and a body section continuous to a radially inner side of the neck section. A locking edge extending in a right-left direction is formed at a radially outer end of the front surface of the body section, and the metal element includes a projection section extending in the right-left direction on a back surface of the body section at a position backward of the locking edge.

Provided is a continuously variable transmission including: a first pulley including a first fixed sheave fixed to a first rotating shaft and a first movable sheave rotating integrally with the first rotating shaft and is movable along the first rotating shaft; a second pulley including a second fixed sheave fixed to a second rotating shaft and a second movable sheave rotating integrally with the second rotating shaft and is movable along the second rotating shaft; and a transmission belt wrapped around a belt wrapping groove formed on the first pulley and around a belt wrapping groove formed on the second pulley. In a belt track for a minimum gear ratio, surfaces of the first pulley that are in contact with the transmission belt have a lower coefficient of friction relative to the transmission belt than surfaces of the second pulley that are in contact with the transmission belt.

Transverse segments (10) for a drive belt (6) for a belt-and-pulley-type continuously variable transmission include a row of these transverse segments (10) mounted on a stack (9) of several, mutually nested rings. The transverse segments (10) are provided with a protrusion (40) that protrudes from a front surface (11) thereof and with a corresponding cavity (41) that is provided in a back surface (12) thereof. An offset is provided between the protrusion (40) and the cavity (41) in the radial direction of the drive belt (6), such that in the row of transverse segments (10) in the drive belt (6) these will be inclined backwards by the forced insertion of the protrusion (40) into the cavity (41).
