Claims (3)

  The movable pulley half (63) that constitutes the drive pulley (58) together with the fixed pulley half (62) fixed to the input shaft (16) is on the driven pulley (59) side attached to the output shaft (61). Relative movement in the axial direction so as to change the width of the belt groove (64) formed between the endless V belt (60) for transmitting power and the fixed pulley half (62) by winding the endless V belt (60). And one end of a slide gear (114) that is slidable in the axial direction of the input shaft (16) cannot be relatively moved in the axial direction, and can be moved relative to the input shaft (16). The cylindrical screw shaft (115) is connected to the movable pulley half (63) so as to be relatively rotatable, and is arranged coaxially with the input shaft (16) with the axial position and the position around the axis being constant. In the V-belt continuously variable transmission to which the slide gear (114) is screwed, the screw gear 114 and the screw shaft (115) have an end wall (116a). A V-belt type continuously variable transmission which is covered with a cover (116) formed in a bottom cylindrical shape. A member disposed on the outside by the screwed portion of the slide gears (114) and said screw shaft (115), ring-shaped sealing member (124) through between the inner circumference of the cover (116) The V-belt type continuously variable transmission according to claim 1, wherein the V-belt continuously variable transmission is mounted. The cover (116) is disposed so as to be sandwiched between the screw shaft (115) and a support plate (118) that fixes the screw shaft (115) to the crankcase (12). The V-belt type continuously variable transmission according to claim 1 or 2.
