In this example, pressure ring 22 is kept by spring 32, wherein spring 32 be supported at driven wheel 16 to this
(referring to Fig. 2) in the groove of setting.The active force that pressure ring 22 can resist spring 32 on A in the axial direction moves a certain amount.
Fig. 2 shows driven wheel 16, synchronous ring 24, inner ring 26 and pressure ring 22 are assembled in synchronization unit 10.
Driven wheel 16 has radially projecting protrusion 34, the radial groove 36 being engaged at the interior diameter of pressure ring 22
In, and therefore by pressure ring 22 substantially without with a gap torsionally couple driven wheel 16.
Multiple window shape slots 38 for being circumferentially distributed are set at pressure ring 22, it is outstanding on the A in the axial direction of inner ring 26
Protrusion 40 is engaged to wherein.
Building the first active force in the edge of the circumference of protrusion 40 enhances face 42, extends to being mutually inclined prominent
Play the free end in portion 40.Protrusion 40 has contraction flow region, and inclined surface 42 is located on the side in the front 44 of protrusion 40,
That is, towards the main body of inner ring 26.
At 38 opposed facing circumferential edges of window shape slot, corresponding second active force enhancing face is built in pressure ring 22
