The synchronizer comprises a gear sleeve, protruding parts arranged in the tooth length direction are arranged on the side walls of the two sides of an inner tooth of the gear sleeve, and first inclined parts are arranged at the positions, corresponding to the two ends of the protruding parts, of the side wall of the inner tooth of the gear sleeve respectively. A plane parallel to the side wall of the inner teeth of the gear sleeve is arranged at the edge of the lower end of the first inclined part, and a second inclined part inclined towards the outer side is arranged at the edge of the outer end of the plane. The gear shifting device has the advantages of being capable of preventing the synchronous ring from being blocked during gear shifting, improving gear shifting smoothness and the like. 本实用新型涉及一种车辆变速器用换挡顺畅的同步器，包括齿套，所述齿套的内齿两侧侧壁上设有沿齿长方向设置的凸部，所述齿套的内齿侧壁上对应于凸部的两端分别设有第一斜部，所述第一斜部的下端边沿处设有与齿套内齿的侧壁平行的平面，所述平面的外端边沿处设有朝外侧倾斜的第二斜部。本实用新型具有可避免换挡时同步环发生卡顿，且提高换挡顺畅性等特点。
