Abstract
A continuously variable transmission includes a primary shaft, a secondary shaft, a primary pulley, a secondary pulley, a first power transmission member, a primary sprocket, a secondary sprocket, a second power transmission member, and a power transmission switch. The first power transmission member has a loop shape and is wrapped around the primary pulley and the secondary pulley. The primary sprocket is disposed on the primary shaft. The secondary sprocket is disposed on the secondary shaft. The second power transmission member has a loop shape and is wrapped around the primary sprocket and the secondary sprocket. The power transmission switch disables power transmission by the second power transmission member when the first power transmission member is in a normal condition and enables the power transmission by the second power transmission member when the first power transmission member is in an abnormal condition.
