Here, the first peeling section and the second peeling section are located at a position of a difference between the first and second outgoing lines, and when the adhesive is injected and sealed, the first and second peeling sections are overlapped and contacted The first filling section and the second filling section are sealed while being enclosed in the sealing cavity by the injection of the respective adhesives, so that the waterproof effect is excellent. On the other hand, in the first filling section and the second filling section, It also prevents the motor drive from being interrupted by the contact of the peeling section.

Preferably, the first outgoing line and the second outgoing line are parallel to each other, and the first and second peeling sections are staggered in the longitudinal direction of the first outgoing line and the second outgoing line. Since the first peeling section and the second peeling section are staggered from each other in the longitudinal direction of the first lead line and the second lead line, when the adhesive is injected and sealed, the first and second peeling sections are overlapped and contacted The first and second peeling sections can be sealed and sealed by the adhesive injection in the sealing cavity to ensure an excellent waterproofing effect and on the other hand to the first peeling section and the second peeling section, Thereby preventing the motor driving from being interrupted due to the contact of the second peeling section.

Preferably, since the sealing cavity and the end cover lead-out line hole are adjacent to each other, the first and second peeling sections and the second peeling section are sealed, and the lead-out line hole is also sealed. And more preferably the waterproof sealing effect of the motor is further improved.

Preferably, the first peeling section and the second peeling section are sealed by an epoxy resin in the sealing cavity. Organic silicon, polyurethane, silicone sealant and the like can also be used as a material for sealing by injecting an adhesive.
