A synchronizing device in gear shift transmissions has a gear ( 28 ), a shift sleeve ( 30 ) which is displaceably engaged with the gear ( 28 ) by internal teeth ( 32 ), and thrust members ( 10 ) disposed between the gear ( 28 ) and the shift sleeve ( 30 ), each of the thrust members having a casing ( 12 ) accommodated in an axial groove ( 40 ) of the gear ( 28 ), and a spring ( 18 ) biasing a pressure member ( 14 ) against the internal teeth ( 32 ) of the shift sleeve ( 30 ). The thrust member ( 10 ) is shaped as a flat parallelepiped, and the spring ( 18 ) extends transversely of the biasing direction and is supported on the casing ( 12 ) or the gear ( 28 ) with its peripheral portion and supports the pressure member ( 14 ) with is central portion.
