DRUM TYPE-VARIABLE SPEED DRIVE A drum type-variable speed drive in which: a spring bearing member (91), which is restricted from moving in the axial direction of departing from a shift fork (83) by a locking member (84, 85) fixed to a shift fork shaft (81), is pivotally supported by the shift fork shaft (81); a lost motion spring (90) is interposed between the spring bearing member (91) and the shift fork (83); and movement of the shift fork shaft (81) in the axial direction caused by rotation of a shift drum (100) presses the spring bearing member (91) through the locking member (84, 85), whereby the spring load of the lost motion spring (90) acts on the shift fork (83). -C-J - -n KA{ThV / A / C / / V i / / / N, I r~ a U''' ~/ <~*~ / fcN / / 2 x,~ 7 N~- CO A/ ~ (A( vi 7 ~ r ~~-4;~( 49K tc 9 ~ <K t/ <// /) '~ 'N ~ ~/ VN N (/2' >y s~4$4 ~ x~&~ V r ( VA K § S N.
