The utility model relates to a novel reverse gear idle wheel mounting structure, casing, idler shaft and idler shaft locking plate behind reverse gear idle wheel, derailleur, the idler shaft pass casing behind the derailleur, reverse gear idle wheel installs and puts on the idler shaft through the bearing cover in that the derailleur backshell is internal, the idler shaft locking plate for gear -type form, its install behind the derailleur on the casing with the idler shaft fluting in dentate structure match. This structure can make derailleur when operation idler shaft warp for a short time and difficult appearance not hard up, and reverse gear idle wheel beats the tooth probability and hangs down. 本实用新型涉及种新型倒挡惰轮安装结构，包括倒挡惰轮、变速器后壳体、惰轮轴和惰轮轴锁片，所述的惰轮轴穿过变速器后壳体，倒挡惰轮安装在变速器后壳体内通过滚针轴承套置在惰轮轴上，所述的惰轮轴锁片为齿轮形状，其安装在变速器后壳体上与惰轮轴开槽内的齿状结构相配合。该结构可使变速器运转时惰轮轴变形小且不易出现松动，倒挡惰轮打齿概率低。
