Abstract

The invention relates to a synchronizer hub (1) comprising a hub body (4) that, on the outer circumference (5) thereof, has a sleeve toothing (6) for engagement of a sliding sleeve (6a), said sleeve toothing being interrupted by at least one first axial recess (7) and by at least one second axial recess (8), wherein the first axial recess (7) has first lateral faces (14, 15) and the second axial recess (8) has second lateral faces (17, 18), and wherein the first lateral faces (14, 15) are inclined to the axial direction at a first angle (20). The second lateral faces (17, 18) of the second axial recess (8) run at a second angle (21) to the axial direction, wherein the second angle (21) is not equal to the first angle (20) of the first lateral faces (14, 15).
