Thereby, the waterproofness between the workpiece | work 20 and the wall part 12 is ensured.

  Next, with reference to FIGS. 3 and 4, the seal sticking jig 50 according to one embodiment of the present invention will be described. The seal sticking jig 50 is a jig used when sticking the seal member 40 to the sticking area W of the workpiece 20. As shown in FIG. 3, the seal sticking jig 50 includes a main body 52. The main body 52 is formed in a rectangular ring shape from metal, for example. The thickness T1 of the main body 52 is about half of the thickness T2 of the seal member 40 (see FIG. 7). The main body 52 is provided with an opening 54 having a shape corresponding to the pasting region W (in this example, a rectangular shape). In other words, the shape of the opening 54 is a shape corresponding to the outer shape of the seal member 40. As will be described later, the protruding portion 26 of the workpiece 20 is inserted into the opening 54 (see FIGS. 5 and 6).

  As shown in FIG. 4, the main body 52 is provided with a plurality (four in this example) of positioning holes 56. These positioning holes 56 are located at the positions of the attachment holes 28 when the attachment region W of the workpiece 20 is aligned with the openings 54 of the main body 52 (positions of the attachment holes 28 when the protruding portions 26 are inserted through the openings 54). It is provided at a corresponding position (position of the positioning pin 58 in FIG. 3). A positioning pin 58 described later is inserted into the positioning hole 56. The positioning hole 56 is a screw hole in this example, and can fasten a fastening portion 64 described later.

The second non-adhesion processing unit 72 is provided on the entire inner peripheral surface of the opening 54. In this example, the first non-adhesion processing unit 70 and the second non-adhesion processing unit 72 are continuous.

  Next, a method for sticking the seal member 40 to the workpiece 20 using the seal sticking jig 50 will be described. First, as shown in FIG. 5, the protruding portion 26 of the work 20 is inserted into the opening 54 of the seal sticking jig 50, and the sticking area W of the work 20 is aligned with the opening 54 of the main body 52, 55, the main body 52 of the sticking jig 50 is positioned with respect to the workpiece 20. More specifically, by placing the main body 52 of the seal sticking jig 50 on the mounting surface 24 of the workpiece 20 so that the pin-shaped portion 66 of the positioning pin 58 is inserted into the mounting hole 28 of the workpiece 20. The main body 52 is positioned with respect to the workpiece 20. That is, in this example, the operation of inserting the protruding portion 26 through the opening 54 and the operation of positioning the main body 52 with respect to the workpiece 20 by the positioning portion 55 are simultaneously performed. As shown in FIG. 5, in the state where the main body 52 is positioned with respect to the workpiece 20, a gap S is formed between the protrusion 26 and the inner peripheral surface of the opening 54.

  Next, as shown in FIG. 6, the seal member 40 is inserted into the opening 54 from one end side of the opening 54 and along the inner peripheral surface of the opening 54, whereby the seal member 40 is placed in the pasting region W of the workpiece 20. It is pasted. At this time, as shown in FIG. 7, the seal member 40 enters the gap S between the protruding portion 26 and the inner peripheral surface of the opening 54 and is attached to the mounting surface 24 of the base portion 22. A predetermined interval is left between the pasted seal member 40 and the protruding portion 26.

  The sticking of the sealing member 40 to the workpiece 20 is completed by the above procedure. Thereafter, for example, the seal sticking jig 50 is removed from the workpiece 20. Next, the workpiece 20 to which the seal member 40 is attached is attached to the attachment opening 14 of the wall portion 12 in the housing 10. At this time, the seal member 40 is compressed between the mounting surface 24 of the workpiece 20 and the wall portion 12 and is deformed so as to enter the gap S. In this example, in order to ensure this deformation allowance, a gap is provided between the seal member 40 and the protruding portion 26 as described above.

  As described above, in the seal sticking method using the stick sticking jig 50, the sticking area W of the work 20 is aligned with the opening 54 of the main body part 52, and the main body part 52 is positioned with respect to the work 20 by the positioning part 55. . Then, the seal member 40 is affixed to the affixing region W of the workpiece 20 by inserting the seal member 40 into the opening 54 from one end side of the opening 54 and along the inner peripheral surface of the opening 54. Thereby, the seal member 40 can be affixed to the predetermined affixing region W with high accuracy. Therefore, it is possible to improve the pasting accuracy of the seal member 40. Further, since the first non-adhesion processing portion 70 is provided at the peripheral portion of the opening 54, when the sealing member 40 is accidentally brought into contact with the peripheral portion of the opening 54 when the sealing member 40 is attached, It can suppress that the sealing member 40 adheres to the said peripheral part. Therefore, according to the seal sticking jig 50, it is possible to ensure the workability of the sticking work while improving the sticking accuracy of the seal member 40.

  Further, in the sticker sticking jig 50, the main body 52 is positioned with respect to the work 20 using the attachment hole 28 for attaching the work 20 to the housing 10 (attachment target). Since it is not necessary to provide the positioning structure for the workpiece 20, the structure of the workpiece 20 can be prevented from becoming complicated, and the cost can be reduced. Further, since the mounting hole 28 serving as a reference for the mounting position with respect to the housing 10 in the workpiece 20 is used for positioning the seal sticking jig 50, the mounting accuracy of the seal sticking jig 50 can be improved, and consequently the seal member 40. The pasting accuracy of can be improved.

  Further, in the seal sticking jig 50, since the second non-adhesion processing portion 72 is provided on the inner peripheral surface of the opening 54, the seal member is mistakenly attached to the inner peripheral surface of the opening 54 when the seal member 40 is attached. Even if 40 is brought into contact, the sealing member 40 is prevented from sticking to the inner peripheral surface of the opening 54. Therefore, the workability of the pasting work can be further improved.

  Further, in the seal sticking jig 50, the first non-adhesion processing unit 70 and the second non-adhesion processing unit 72 are continuous, and therefore the seal member 40 is attached to one end of the opening 54 when the seal member 40 is applied. It is possible to effectively suppress sticking to the peripheral edge portion or the inner peripheral surface of the opening 54, and the workability of the sticking work can be improved.
