When the vehicle door opening/closing device configured as described above is attached to the vehicle body B, the motor module 20, the transmission module 30, and the center guide unit CG can be handled independently of each other. That is, between the motor module 20 and the transmission module 30, the female spline 331a of the driving pulley 331 and the motor module 20 are disconnected. Between the transmission module 30 and the center guide unit CG, the connection state between the belt bracket 234 and the arm member 11C is released.

From this state, for example, after first attaching the guide rail 10C to the quarter panel QP, the transmission module 30 and the motor module 20 are sequentially attached to the quarter panel QP, and the transmission module 30 and the motor module 20 are connected to each other. , the sliding door RD can be driven by the vehicle door opening/closing device.

Specifically, the input section unit 330 of the transmission module 30 is inserted into the vehicle interior through the component insertion hole Qa formed in the quarter panel QP, and from this state, the fastening hole 333a of the mounting plate section 333 and the seal member 334 are inserted. The attachment plate portion 333 can be attached to the quarter panel QP by providing a fastening member such as a bolt in the fastening insertion opening 334b2 and the fastening insertion hole Qb of the quarter panel QP. Furthermore, by attaching the belt guide 230 of the transmission module 30 to the quarter panel QP, the transmission module 30 can be supported by the quarter panel QP. Further, if the motor module 20 is connected to the input unit 330 inside the vehicle from this state, the motor module 20 and the transmission module 30 are attached to the quarter panel QP in a state in which the drive belt 130 can be moved by driving the motor module 20. can be installed.

At this time, according to the above-described door opening/closing device, since the planar seal member 334 is interposed between the mounting plate portion 333 and the quarter panel QP, the component insertion hole Qa formed in the quarter panel QP is In addition, it is possible to prevent external water such as rainwater and dust from entering the inside of the vehicle through the fastening insertion hole Qb. In particular, since an outer peripheral lip 41 is provided on the edge that is the outer periphery of the seal member 334 and an inner peripheral lip 42 is provided around portions corresponding to the component insertion hole Qa and the fastening insertion hole Qb, the mounting plate Even if there is a processing error or an assembly error between the portion 333 and the quarter panel QP, it is possible to more reliably prevent the entry of water and dust from the outside.

Moreover, since the outer peripheral lip 41 and the inner peripheral lip 42 of the seal member 334 project so as to be inclined toward the vehicle outer surface Pa of the quarter panel QP, they are brought into contact with the vehicle outer surface Pa via the mounting plate portion 333. At this time, the tip portion is always bent so as to face the edge portion of the mounting plate portion 333 . Therefore, as long as the transmission module 30 is attached to the quarter panel QP, it is possible to reproduce a state in which it is difficult for water and dust to enter between the end edge of the mounting plate portion 333 and the quarter panel QP. can be obtained easily and stably. In addition, while the central portion of the seal member 334 is configured to be thin, the surface of the seal member 334 facing the mounting plate portion 333 has an inner peripheral rib 51 and an outer peripheral rib corresponding to the inner peripheral lip 42 and the outer peripheral lip 41. 52 are provided. Therefore, the inner peripheral rib 51 and the outer peripheral rib 52 allow the inner peripheral lip 42 and the outer peripheral lip 41 to reliably abut on the vehicle outer surface Pa of the quarter panel QP, and the central portion and the mounting plate are configured to be thin. The plate thicknesses of the inner peripheral lip 42 and the outer peripheral lip 41 can escape through the gap d formed between the surface of the portion 333 . Furthermore, around the fastening hole 333a, the protrusion 333a1 secures a gap X between the quarter panel QP and the vehicle outer surface Pa. be able to. As a result, even if the mounting plate portion 333 is attached so as to be strongly pressed against the quarter panel QP, the outer peripheral lip 41 and the inner peripheral lip 42 of the sealing member 334 are properly crushed, and the quarter panel QP is deformed. Intrusion of water and dust can be prevented without inviting a situation that causes a failure. Furthermore, since a single seal member 334 may be used, there is no concern that the component mounting work will be complicated.

After the transmission module 30 is attached to the quarter panel QP, the belt bracket 234 of the drive belt 130 is superimposed on the arm member 11C, and the connecting screw CB is screwed to the arm member 11C via the belt bracket 234. The transmission module 30 and the center guide unit CG can be connected with each other. In this state, when the motor module 20 is driven, the drive belt 130 moves in an appropriate direction with respect to the belt guide 230 , and the belt bracket 234 moves with respect to the belt guide 230 accordingly. As a result, the movement of the drive belt 130 is transmitted to the arm member 11C via the belt bracket 234, so that the slide door RD connected to the arm member 11C can be moved in the longitudinal direction with respect to the vehicle body B. becomes.

In the above-described embodiment, the input section unit 330 of the transmission module 30 is attached to the quarter panel QP that constitutes the vehicle body, but this is also applicable to the case of attaching other parts to other panels. It is possible. In this case, the number of fastening insertion holes does not necessarily have to be four.

In the above-described embodiment, the mounting plate portion 333 has the fastening hole 333a, and the fastening member is inserted through the fastening hole 333a. I do not care.

Furthermore, in the above-described embodiment, the plate thickness of the central portion of the seal member 334 is configured to be small, and the ribs 51 and 52 are provided on the surface facing the mounting plate portion 333 to provide the gap d that serves as a relief recess. However, the present invention is not necessarily limited to this, and it is also possible to configure relief recesses by forming recesses only in the portions of the seal member 334 corresponding to the lips 41 and 42 .
