FIG. 1 is a cross-sectional view of a main part showing a gasket holding part between a glass edge and a case on the side of a conventional non-circular, thin, waterproof portable watch. The conventional gasket holding part structure has a circumferential step 1b provided on the upper inner periphery of the body 1 and the lower surface of the glass edge 5 to which the glass 7 is fixed via the synthetic resin gasket 8. A space is formed, and rubber gaskets 6 are compressed and attached to the top and bottom to maintain waterproofness, and the glass edge 5 and the body 1 are fixed to each other by caulking the protrusion 5a below the glass edge around the entire circumference or at several points. It was hot.

であつた。 In addition, as another conventional example,
As shown in the publication, the groove in which the gasket is attached is formed by a combination of grooves each having a cross-sectional shape on the body and the glass edge, and the depths of the inner and outer circumferential side walls of the groove are equal. It was something I had.

However, in the prior art shown in FIG.
In addition to the need for a wall thickness l 1 below the circumferential stepped portion 1b of the body 1 in order to swage the circumferential stepped portion 1b, the circumferential stepped portion 1b is required to form a space above which the rubber packing 6 is attached as described above. Since the height of the stepped portion 1b is m 1 , the minimum wall thickness of the body 1 above the inner circumferential lower surface is l 1 + m 1 as a whole, and a non-circular shaped portable watch with waterproof function is obtained. The problem is that the demand for thinner devices cannot be met, at least from this part.

題点を有する。 In addition, in the conventional example shown in Japanese Utility Model Publication No. 44-30103, the depths of the inner and outer peripheral side walls of the groove in the shape of the letter formed on the body and the glass edge are equal, for example, Even if a packing with an irregular profile is set in a groove in the body, the outer shape of the packing before compression is larger than the depth of the groove and is placed so as to protrude into the groove, so its position cannot be determined and the contour of the groove changes. It takes a lot of man-hours to position it according to the groove, and even if it is set in the groove, the position cannot be fixed, so the gasket will pop out with a slight external force and the set position will shift, causing damage to the corner of the groove. If it is compressed while placed on a container, etc., there is a problem in that the seal will break and the waterproofing will be poor. In addition, in this conventional example, since the contour of the groove is non-circular, the curvature of the packing shape that fits the groove is equal, and it is relatively easy to set the packing into the groove. However, if the groove is oval, The problem is that it is necessary to match the shape of the elastic packing with an irregular contour to the non-circular shape, making it extremely difficult to set it into the groove.

FIG. 2 is a cross-sectional view of a main part showing an embodiment of the present invention, and is a cross-sectional view showing a gasket holding part between the glass edge and the glass edge, which has a non-circular planar shape. Torso 1
Circumferential stepped portion 11a provided on the upper surface of the inner circumferential protrusion of No. 1
A space is formed by a circumferential stepped portion 15a provided on the lower surface of the outer periphery of the glass edge 15 to which the glass 17 is integrally fixed via the gasket 18, and the gasket 16
is compressed vertically and installed in the space, so that waterproofness is maintained, and the body 11 and the glass edge 15
and are fixed to each other by inserting a plate member 19 into a groove 15b provided below the edge of the glass.

る。 Further, the space portion has a side wall depth of m 2 in the inner peripheral direction of the circumferential step portion 15a in the glass edge 15.
and the circumferential step portion 1 in the glass edge 15
The depth of the side wall in the outer circumferential direction of 5a is A, and the shell 11
When the depth of the outer circumferential side wall of the circumferential stepped portion 11a is 13, the relationship is formed such that m 2 =A+B. According to this embodiment, the circumferential step 11a of the barrel
Although a wall thickness l 2 is required below the glass edge, the depth (height of the space) m 2 of the inner peripheral side wall of the circumferential step at the glass edge is divided into the glass edge side and the body side.
The glass edge height h in FIG. 1 can be made thinner by at least the depth B of the circumferential step formed on the body side. Also, during press processing, the circumferential step portions 15a and 1 of the glass edge and the body, respectively.
To form 1a, it is only necessary to drive to the depth of dimensions A and B, so no load is placed on the press die, and the life of the die can be extended, resulting in high mass productivity.

As is clear from the dimensional relationship m 2 =A+B, the depth m 2 of the inner peripheral side wall of 5a is formed deeper than the other side walls A and B to such an extent that the packing 16 does not protrude, for example. Circumferential stepped portion 1
When attaching the packing 16 having a circumferential length slightly shorter than the circumferential length of the inner circumferential side wall of 5a to the circumferential stepped portion 15a, the packing 16 is bitten and supported by the inner circumferential side wall to be stable and ensure that the circumference is fixed. Since it can be attached to the stepped portion 15a, the glass edge 15, body 11, and gasket 16
The workability when assembling the plate-like member 19 and the like can be significantly improved.

は薄くできる。[Effects of the Invention] As described above, according to the present invention, the space in which the packing is attached has a non-circular shape and a circumferential stepped portion provided on the lower surface of the outer periphery of the glass rim to which the non-circular glass is integrally fixed. The depth of the inner circumferential side wall of the circumferential step at the glass edge is m2, and the depth of the inner circumferential side wall of the circumferential step at the glass edge is m2 . When the depth of the outer circumferential side wall is A, and the depth of the outer circumferential side wall of the circumferential stepped portion of the body is B, by satisfying the relationship m 2 = A + B, the inner circumference of the circumferential stepped portion at the glass edge is The depth of the side wall (height of the space) m 2 is divided into the glass edge side and the body side, so the glass edge height is at least the depth B dimension of the side wall of the circumferential step formed on the body side. You can make it thinner.

く不良特性が解消できる効果を有する。 Furthermore, as is clear from the above-mentioned dimensional relationship m 2 =A+B, the inner circumferential side wall depth m 2 of the circumferential stepped portion at the glass edge protrudes more than the other side wall depths A and B mentioned above. For example, when installing a gasket whose peripheral length is slightly shorter than the peripheral length of the inner circumferential side wall of the circumferential stepped portion at the glass edge, the gasket is formed so deep that it does not exceed the conventional technology. It was extremely difficult. Even if the contour of the circumferential step is non-circular, it is bitten and held by the inner circumferential side wall of the circumferential step and is extremely easily positioned and fixed, ensuring that the circumferential step of the glass edge is Since it can be attached to the inner circumferential side wall, the packing will not come off the circumferential stepped part of the glass edge, and the work efficiency when assembling the glass edge, body, packing, plate-shaped members, etc. can be significantly improved, and the packing can be attached to the circumferential side wall. It has the effect of eliminating the defective characteristics that lead to waterproofing defects, such as being placed in a misaligned position at a corner of a stepped portion, etc., and being compressed in this state, causing the packing to break.
