Claims (2)

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 type continuously variable transmission in which the slide gear (114 ) is screwed to the slide gear (114 ), the screw gear (114) and the screw shaft (115) have an end wall (116a). Covered with a cover (116) formed in a bottom cylindrical shape, the slide gear (114) and the screw shaft (115), and an annular seal member (124) contacting the inner periphery of the cover (116), An annular chamber (123) is formed with the cover (116), and the annular chamber (123) communicates with the outside through communication holes (126, 159). .   The threaded shaft (115) that coaxially surrounds the input shaft (16) with the axial position relative to the input shaft (16) fixed, and the vibration isolating member (120) with respect to the rotational direction around the axis. The V-belt type continuously variable transmission according to claim 1, wherein the V-belt type continuously variable transmission is positioned between the transmission case and the transmission case.
