A synchronizer for manual transmission constructed and arranged to separate a sleeve moved by a shift fork to an inner sleeve and an outer sleeve to soften a gear shifting feel and to improve a durability of transmission. The synchronizer has a hub gear coupled to a main spindle, a speed gear installed on the main spindle relative to a side surface of the hub gear and formed with a clutch gear on an inner surface thereof relative to the hub gear side and a sleeve coupled to an outer circumference of the hub gear 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.
