Abstract

A timepiece case including: a case; a windshield member, a first portion from among a side surface of the windshield member facing the case; a waterproofing member positioned between the case and the windshield member and configured to waterproof an inside of the case; and an exterior member, wherein: the case has a plurality of protrusions that is provided at respective plurality of portions facing the first portion and protrudes from an inner-wall surface of the case toward the first portion, the plurality of protrusions prescribes a position range for the side surface of the windshield member with respect to the case, and the exterior member faces a second portion that is from among the side surface of the windshield member and differs to the first portion.

First claim

The invention claimed is:

1 . A timepiece case comprising:
a case; a windshield member, a first portion from among a side surface of the windshield member facing the case; a waterproofing member positioned between the case and the windshield member and configured to waterproof an inside of the case; and an exterior member, wherein:
the case has a plurality of protrusions that is provided at respective plurality of portions facing the first portion and protrudes from an inner-wall surface of the case toward the first portion,
the plurality of protrusions prescribes a position range for the side surface of the windshield member with respect to the case, and
the exterior member faces a second portion that is from among the side surface of the windshield member and differs to the first portion.

2 . The timepiece case according to claim 1 , wherein the waterproofing member is positioned between the first portion and the case.

3 . The timepiece case according to claim 1 , wherein an entirety of the second portion belonging to the windshield member is not in contact with the exterior member.

4 . The timepiece case according to claim 1 , wherein the waterproofing member is an adhesive.

5 . The timepiece case according to claim 1 , wherein the case has a protrusion that is positioned at a portion facing the first portion, and a support that supports a third portion from among an inner surface the windshield member, the third portion following an outer edge of the inner surface of the windshield member.

6 . The timepiece case according to claim 5 , wherein the waterproofing member is positioned between the third portion and the case.

7 . The timepiece case according to claim 5 , wherein a height of the first portion is less than or equal to a width of the third portion.

8 . The timepiece case according to claim 1 , wherein the second portion belonging to the windshield member is inclined with respect to the first portion.

9 . The timepiece case according to claim 8 , wherein the second portion is a chamfered surface belonging to the windshield member.

10 . The timepiece case according to claim 1 , wherein a height of the first portion is smaller than a height of the second portion.

11 . The timepiece case according to claim 1 , wherein an outer surface of the windshield member is positioned within the same plane as a top surface of the exterior member.

12 . An electronic timepiece, comprising:
the timepiece case according to claim 1 ; a display that is positioned in a manner enabling visual recognition through the windshield member, and is capable of a display pertaining to time; and a controller that is positioned inside the case and controls operation of the display.

13 . The timepiece case according to claim 1 , wherein the plurality of protrusions linearly extends in an up-down direction for the inner-wall surface.

14 . The timepiece case according to claim 4 , wherein the inner-wall surface of the case has the plurality of portions at which the respective plurality of protrusions is provided and a portion at which the plurality of protrusions is not provided, and the adhesive is placed in a gap formed between the first portion and the portion at which the plurality of protrusions is not provided.

15 . The timepiece case according to claim 1 , wherein a tip of each of the plurality of protrusions is positioned, in a plan view, at a same position as an outermost contour of the windshield member or at a position closer to the inner-wall surface than the outermost contour.

16 . The timepiece case according to claim 5 , wherein the support has a protrusion that protrudes upward annularly along an inner edge of the case.
