At this time, the tip of the threaded portion 19a of the second screw member 19 does not come into contact with the tip of the threaded portion 16a of the first screw member 16 and approaches with a gap.

このため、第２ねじ部材１９のねじ部１９ａをねじ止め部７のねじ孔７ａに螺合させて締め付けても、第２ねじ部材１９のねじ部１９ａの先端が第１ねじ部材１６のねじ部１６ａの先端に当接することがないので、第２ねじ部材１９の頭部１９ｂが鍔部１８をバンド取付部３のケース取付片５の下面に押し付ける。このため、裏蓋１７がバンド取付部３のケース取付片５に確実に取り付けられる。 Therefore, even if the screw portion 19a of the second screw member 19 is screwed into the screw hole 7a of the screwing portion 7 and tightened, the tip of the screw portion 19a of the second screw member 19 has the tip of the screw portion of the first screw member 16. The head portion 19b of the second screw member 19 presses the flange portion 18 against the lower surface of the case attachment piece 5 of the band attachment portion 3 because it does not come into contact with the tip end of 16a. Therefore, the back lid 17 is securely attached to the case attachment piece 5 of the band attachment portion 3.

これにより、この腕時計ケースでは、ケース本体１の側部に位置決め部４によって位置決めされたバンド取付部３に、外装部材１１が第１ねじ部材１６によって取り付けられていると共に、裏蓋１７が第２ねじ部材１９によって取り付けられているので、ケース本体１を外装部材１１と裏蓋１７とで挟み込むことができる。 As a result, in this wristwatch case, the exterior member 11 is attached to the band attaching portion 3 positioned by the positioning portion 4 on the side portion of the case body 1, and the back cover 17 is attached to the second portion. Since the case body 1 is attached by the screw member 19, the case body 1 can be sandwiched between the exterior member 11 and the back cover 17.

このため、外装部材１１と裏蓋１７とが外部から衝撃を受けても、その衝撃をバンド取付部３で受け止めることができ、これにより衝撃が直接ケース本体１に加わることがないので、耐衝撃性を高めることができ、かつケース本体１をコンパクトに形成することができるので、ケース全体の小型化を図ることができる。 Therefore, even if the exterior member 11 and the back cover 17 receive an impact from the outside, the impact can be received by the band attaching portion 3, and thus the impact is not directly applied to the case main body 1, so that the impact resistance is high. Since the property can be improved and the case body 1 can be formed compactly, the size of the entire case can be reduced.

すなわち、この腕時計ケースでは、ケース本体１の側部に位置決め部４によって位置決めされたバンド取付部３に外装部材１１が第１ねじ部材１６によって取り付けられているので、外装部材１１がその上方から衝撃を受けると、その衝撃をバンド取付部３で受け止めることができる。このため、外装部材１１が受けた衝撃が直接ケース本体１に加わることがない。 That is, in this wristwatch case, the exterior member 11 is attached to the band attachment portion 3 positioned by the positioning portion 4 on the side portion of the case body 1, so that the exterior member 11 is impacted from above.
