Further, as shown in FIG. 5, a window 12h is formed at the center of the bent portion 12p of the bracket 12, and a striker (not shown) fixed to the edge of the entrance for the window 12h. It is configured to be inserted when the slide door D is closed.

On the front side of the bracket 12, as shown in the door closer principle diagram of FIG. 6 (B), a hook-shaped latch 21 having a lock groove 21m is attached in a state of being rotatable around a support shaft 21p. The latch 21 rotates counterclockwise from the original position to the semi-closed position when the striker inserted from the window portion 12h of the bracket 12 enters the lock groove 21m, and further receives a pressing force from the driven gear 23 and the passive lever 24 described later. It is configured to rotate counterclockwise to the fully closed position. Then, the latch 21 is engaged with the striker in a fully closed position without rattling. Note that the latch 21 receives a force in the direction of returning to the original position (right rotational force) by a spring (not shown).
Further, as shown in FIG. 6A, the bracket 12 is provided with a latch switch 26 for detecting that the latch 21 has rotated to the half-closed position or the fully-closed position.
The driven gear 23 for rotating the latch 21 to the fully closed position is attached to the bracket 12 so as to be rotatable about the support shaft 23p, and an arcuate gear portion 23w is formed at the base end portion of the driven gear 23.

When the slide door D is closed and the striker enters the lock groove 21m of the latch 21 from the window portion 12h of the bracket 12 of the door closer 10, the latch 21 is pressed by the striker and rotates to the semi-closed position. And the latch 21 is hold | maintained in this semi-closed position because the semi-closed claw part 21e of the latch 21 engages with the pole 25. FIG. When this state is detected by the latch switch 26, the electric motor 32 rotates forward, the pinion gear 32p rotates, and the driven gear 23 rotates clockwise (rotates in the direction of the arrow). As a result, the passive lever 24 moves downward and the latch 21 rotates in the direction of the arrow from the half-closed position to the fully-closed position, and the latch 21 engages with the striker without any backlash. Furthermore, when the fully closed claw portion 21c of the latch 21 is engaged with the pole 25, the latch 21 is held in this fully closed position.
When the latch 21 is held in the fully closed position, this is detected by the latch switch 26, and based on this, the electric motor 32 is reversed. As a result, the driven gear 23 is rotated counterclockwise, and the driven gear 23 is returned to the initial position together with the passive lever 24.
Next, when opening the slide door D, if the open lever 28 is rotated counterclockwise by operating an opening handle (not shown), the pole 25 is rotated in the unlocking direction by the open lever 28, and the pole 25 and the latch 21 are disengaged. Thereby, the latch 21 is returned to the original position by the force of the spring, and the engagement between the latch 21 and the striker is released.
That is, the door closer 10 corresponds to the electrical component of the present invention, and the bracket 12 corresponds to the fixing part of the electrical component of the present invention. Further, the electric motor 32, the latch 21 and the like, and various switches attached to the front side of the bracket 12 correspond to the electric component main body of the present invention. Further, the inner panel De of the slide door D corresponds to the mounted part of the present invention.

<Connector part and seal part of door closer 10>
The housing 32z of the electric motor 32 of the door closer 10 is provided with a resin connector 40 to which the electric wiring of the electric motor 32 and the electric wiring of the latch switch 25 and the open switch 29 are connected. In the connector portion 40, a connector (not shown) connected to one end of an electrical wiring from an electronic control unit (not shown) or the like is a through hole 45 for electrical wiring (not shown) formed in the inner panel De of the slide door D. 1, see FIG. 3).
The connector 40 is covered with a rubber seal 50 as shown in FIGS. The seal portion 50 is a portion that covers the outer peripheral surface of the connector portion 40 and connects the connector portion 40 and the through hole 45 of the inner panel De in a sealed state from the periphery, and is formed in a substantially cylindrical shape.
The seal portion 50 includes an attachment portion 52 that is attached to the connector portion 40 by covering the outer peripheral surface of the connector portion 40, and protruding portions 53, 55, 57 that protrude in the axial direction from the distal end surface 43 of the connector portion 40. ing. And in the protrusion parts 53, 55, 57 of the seal part 50, a ring-shaped insertion part 57, a flange-shaped contact part 55, and a connecting part 53 configured to be deformable in the axial direction are arranged in order from the tip side. It is formed coaxially. The insertion portion 57 is a portion that is inserted into the through hole 45 of the inner panel De, and the outer diameter dimension of the insertion portion 57 is set smaller than the inner diameter dimension of the through hole 45. The abutting portion 55 is a portion that abuts on the peripheral portion of the through hole 45 in a state where the insertion portion 57 is inserted into the through hole 45 of the inner panel De, and provides a sealing property between the through hole 45 and the seal portion 50. Work to secure. Since the connecting portion 53 is configured to be deformable in the axial direction, the peripheral portion of the through hole 45 of the inner panel De from the front end surface 52f of the mounting portion 52 (same position in the axial direction as the front end surface 43 of the connector portion 40). And the distance from the front end surface 52f of the mounting portion 52 to the contact portion 55 of the seal portion 50 is absorbed.

  As shown in FIGS. 1A and 1B, a reinforcing portion 60 is fixed to the seal portion 50 on the inner peripheral side of the insertion portion 57 and the contact portion 55. The reinforcing portion 60 prevents the deformation of the insertion portion 57 and the abutting portion 55 and also has a cylindrical shape for holding the minimum dimension from the distal end 63 of the insertion portion 57 to the distal end surface 43 of the connector portion 40 at a constant value J. Is the body. The reinforcing portion 60 includes a cylindrical portion 62 that covers the inner peripheral surfaces of the insertion portion 57 and the contact portion 55, and a flange portion 63 that is formed at the distal end of the cylindrical portion 62 and covers the distal end surface 57 f of the insertion portion 57. It is configured. Further, on the proximal end side of the cylindrical portion 62 in the reinforcing portion 60, an expanded portion 62w is formed in accordance with the shape of the connecting portion 53. The reinforcing portion 60 is made of a resin or metal that is not easily deformed, and its axial length dimension is set to a dimension J. For this reason, even if the distal end 63 of the seal portion 50 (the flange portion 63 of the reinforcing portion 60) receives a pressing force from the axial direction, the insertion portion 57 and the contact portion 55 are not deformed, and only the connecting portion 53 has an axial length dimension. It will be deformed in the direction of decreasing. And if the expansion part 62w of the reinforcement part 60 contact | abuts to the front end surface 52f of the attachment part 52 by deformation | transformation of the connection part 53 of the seal | sticker part 50, the front end surface 52f of the attachment part 52 (front end surface 43 of the connector part 40). And the distance between the front-end | tip 63 of the seal | sticker part 50 becomes equal to the dimension J (refer FIG. 1 (A)). That is, even if the tip 63 of the seal portion 50 receives an axial pressing force, the distance from the tip 63 of the seal portion 50 to the tip surface 52f of the attachment portion 52 (tip surface 43 of the connector portion 40) is the dimension J (minimum). Dimension) is never smaller.

<Fixing the door closer 10>
As shown in FIG. 1B and FIG. 3, the door closer 10 passes the insertion portion 57 of the seal portion 50 through the through hole 45 of the inner panel De, and the contact portion 55 of the seal portion 50 is the periphery of the through hole 45. The female screw hole 12w of the bracket 12 is aligned with the bolt hole Dh (see FIG. 3) of the inner panel De in a state of being in contact with the portion. Then, a bolt (not shown) is screwed into the female screw hole 12w of the bracket 12 from the outside of the inner panel De through the bolt hole Dh, whereby the door closer 10 is fixed to the inner panel De. When the distance between the distal end surface 43 of the connector portion 40 and the peripheral edge portion of the through hole 45 of the inner panel De when the door closer 10 is correctly fixed to the inner panel De is S (see FIG. 1B), the seal The axial length dimension J of the reinforcing part 60 of the part 50 is set to a value sufficiently larger than the distance S. Therefore, as shown in FIG. 1A and FIG. 4, when the tip 63 of the insertion portion 57 of the seal portion 50 is in contact with the peripheral edge of the through hole 45 of the inner panel De, the door closer 10 is attached to the inner panel De. It is not positioned at a fixed position.

<Advantages of the door closer 10 according to this embodiment>
According to the door closer 10 according to the present embodiment, the minimum dimension J from the distal end 63 of the insertion portion 57 to the mounting portion 52 when the connecting portion 53 of the seal portion 50 is elastically deformed in a direction to reduce the axial dimension is the door closer. It is set to be larger than the distance S from the attachment portion 52 when the 10 is fixed to the inner panel De to the peripheral edge portion of the through hole 45 of the inner panel De (see FIG. 1B). Therefore, the state in which the tip 63 of the insertion portion 57 of the seal portion 50 is in contact with the peripheral portion of the through hole 45 (see FIG. 1A and FIG. 4), that is, the insertion portion 57 of the seal portion 50 is the inner panel De. In a state where it is not passed through the through-hole 45, the connector portion 40 connected to the attachment portion 52 of the seal portion 50 is not disposed at a proper position. That is, the door closer 10 including the connector portion 40 is not disposed at a regular position that can be fixed to the inner panel De (see FIG. 4). For this reason, the position of the female screw hole 12w provided in the bracket 12 of the door closer 10 and the position of the bolt hole Dh of the inner panel De shift, and the door closer 10 cannot be bolted to the inner panel De. Therefore, there is no problem that the door closer 10 is erroneously fixed to the inner panel De in a state where the insertion portion 57 of the seal portion 50 is not passed through the through hole 45 of the inner panel De.
Further, the seal portion 50 is not deformed into an unnatural shape by the function of the reinforcing portion 60 that is a cylindrical body. Therefore, the minimum dimension J from the tip 63 of the insertion portion 57 to the attachment portion 52 when the connecting portion 53 of the seal portion 50 is elastically deformed can be maintained at a constant value.

<Example of change>
In addition, this invention is not limited to the said embodiment, The change in the range which does not deviate from the summary of this invention is possible. For example, in the present embodiment, the door closer 10 is illustrated as an example of the electrical component, but the present invention can also be applied to electrical components other than the door closer 10.
Moreover, in this embodiment, although the example which comprises the seal part 50 from the rubber part and the resin or metal reinforcement part 60 was shown, for example, the seal part 50 is integrally molded with resin, and the seal part 50 is formed. It is also possible to form only the connecting portion 53 in a so-called bellows shape that can be deformed in the axial direction. Furthermore, the insertion part 57 and the contact part 55 of the seal part 50 can be formed of resin or the like, and only the connecting part 53 can be made of rubber.
