Abstract A synchronizer for hand-driven speed-variation device has a hub gear, a speed gear, a clutch gear and a sleeve to move toward an axial direction during gear shifting and to be synchronized to the clutch gear. The sleeve includes: an inner sleeve coupled to an outer circumference of the hub gear to move axially during gear shifting and to be meshed to the clutch gear; an outer sleeve positioned at an outer circumference of the inner sleeve and receiving a manipulating power of gear shift from a driver to move axially; and a buffer interlocking unit installed between the inner sleeve and the outer sleeve to make the inner sleeve move along the outer sleeve and to simultaneously function smoothly.
