<p>A V-belt-type continuously variable transmission, provided with a shift member (20) connected with free relative rotation and no relative movement in the axial direction to a movable pulley half (17) via a bearing (21), and a shift control mechanism (26) for operating the shift member (20) in the axial direction with the output of an electric motor (24). The shift member (20) comprises a hub (20a) connected to a movable pulley half (17) via a bearing (21), and an arm (20b) extending in the radial direction formed integrally with the hub (20a), and the shift control mechanism (26) comprises a threaded shaft (27)rotationally driven by the output of the electric motor (24) supported with free rotation by the transmission case (2) on one side of the input axis (4), and a female threaded member (28) screwed onto the threaded shaft (27), with the female threaded member (28) and the arm (20b) connected to each other. This configuration provides a structurally simple V-belt-type continuously variable transmission allowing a small number of replacement parts when changing a specification of the apparatus, and keeping the change cost low.</p> |
