[0003] In the prior art, when bolts are used to connect the stator housing to the end cover and the rear cover, it is first necessary to align the threaded connection holes on the stator housing with the threaded connection holes on the end cover and the rear cover. However, since the stator housing, the end cover and the rear cover do not have a good positioning structure, a certain amount of time is wasted in the process of aligning the connection holes, thereby reducing the efficiency of the connection work. Moreover, after the stator housing, the end cover and the rear cover are connected together, they do not have a good sealing structure, which may cause external dust to enter the interior of the stator housing through the gaps between the stator housing, the end cover and the rear cover and be adsorbed on the starter, thereby affecting the heat dissipation effect of the starter, and may further cause the starter to overheat and short-circuit. Therefore, a starter stator housing sealing structure is needed. Utility Model Content
