As shown in FIG. 1, this wristwatch includes a wristwatch case 1. A band attachment portion 2 to which a watch band (not shown) is attached is provided on the 12 o'clock side and the 6 o'clock side of the wristwatch case 1, respectively. Further, switch devices 3 are provided on the 2 o'clock side, 3 o'clock side, 4 o'clock side, 8 o'clock side, and 10 o'clock side of the wristwatch case 1, respectively.

この腕時計ケース１は、図１〜図４に示すように、第１ケース４と、この第１ケース４の上部に取り付けられる第２ケース５と、第１ケース４の外周にこれを覆って配置されて第２ケース５に取り付けられる外装部材である外装ケース６と、を備えている。第１ケース４は、内部に時計モジュール（図示せず）を収納するものであり、筒状の外周部４ａと底部４ｂとを備え、これらが硬質の合成樹脂によって一体に形成された構造になっている。 As shown in FIGS. 1 to 4, the wristwatch case 1 is arranged so as to cover the first case 4, the second case 5 attached to the upper part of the first case 4, and the outer periphery of the first case 4. It is provided with an exterior case 6 which is an exterior member to be attached to the second case 5. The first case 4 houses a watch module (not shown) inside, and has a cylindrical outer peripheral portion 4a and a bottom portion 4b, which are integrally formed of a hard synthetic resin. ing.

すなわち、この第１ケース４は、図２〜図４に示すように、硬質の合成樹脂、例えばポリアミド樹脂にガラス繊維またはカーボン繊維を混入させた剛性の高い硬質の合成樹脂によって形成されている。この第１ケース４の外周部４ａの外周面には、係止凸部７が設けられている。この係止凸部７は、外周部４ａの上部側における外周面から突出して設けられている。 That is, as shown in FIGS. 2 to 4, the first case 4 is formed of a hard synthetic resin, for example, a hard synthetic resin having high rigidity in which glass fibers or carbon fibers are mixed with a polyamide resin. A locking convex portion 7 is provided on the outer peripheral surface of the outer peripheral portion 4a of the first case 4. The locking convex portion 7 is provided so as to project from the outer peripheral surface on the upper side of the outer peripheral portion 4a.

この場合、係止凸部７は、図２〜図４に示すように、外周部４ａの外周面における全周に亘って設けられていることが望ましいが、部分的に設けられていても良い。また、この係止凸部７は、外周部４ａの外周面から突出する長さが、第１ケース４の肉厚よりも十分に薄い長さ、例えば外周部４ａにおける下部側の肉厚の１/３程度の長さで形成されている。 In this case, as shown in FIGS. 2 to 4, it is desirable that the locking convex portion 7 is provided over the entire circumference of the outer peripheral surface of the outer peripheral portion 4a, but it may be partially provided. .. Further, the locking convex portion 7 has a length such that the length protruding from the outer peripheral surface of the outer peripheral portion 4a is sufficiently thinner than the wall thickness of the first case 4, for example, 1 of the wall thickness on the lower side of the outer peripheral portion 4a. It is formed with a length of about / 3.

また、第１ケース４の上端面には、図２〜図４に示すように、ケースパッキン８が装着するパッキン溝４ｃが全周に亘って連続して設けられている。ケースパッキン８は、断面形状が円形で、全体がリング状に形成されている。パッキン溝４ｃは、その深さがケースパッキン８の断面形状における半径と同程度の深さに形成されている。このため、ケースパッキン８は、パッキン溝４ｃ内に装着された際に、上部側の半分程度が第１ケース４の上端面から上方に突出するように構成されている。 Further, as shown in FIGS. 2 to 4, packing grooves 4c to which the case packing 8 is mounted are continuously provided on the upper end surface of the first case 4 over the entire circumference. The case packing 8 has a circular cross-sectional shape and is formed in a ring shape as a whole.

次に、このような腕時計ケース１の作用について説明する。
この腕時計ケース１を組み立てる場合には、まず、第１ケース４の外周に外装ケース６を装着する。このときには、外装ケース６を第１ケース４に下側から挿入させて、第１ケース４の外周部４ａに設けられた係止凸部７を外装ケース６の内周面に設けられた係合凹部１０に係合させる。 Next, the operation of such a wristwatch case 1 will be described.
When assembling the wristwatch case 1, first, the outer case 6 is attached to the outer circumference of the first case 4. At this time, the outer case 6 is inserted into the first case 4 from below, and the locking convex portion 7 provided on the outer peripheral portion 4a of the first case 4 is engaged with the inner peripheral surface of the outer case 6. Engage with recess 10.

すると、外装ケース６の係合凹部１０の下端部１０ａが第１ケース４の係止凸部７の下端部７ａに当接して保持される。これにより、第１ケース４の外周部４ａに外装ケース６が上方に抜け出すことなく装着される。この状態で、第１ケース４の上端面に設けられたパッキン溝４ｃにケースパッキン８を上方に突出させた状態で配置する。この状態で、第１ケース４と外装ケース６との上端部に第２ケース５を配置させる。 Then, the lower end portion 10a of the engaging recess 10 of the outer case 6 comes into contact with the lower end portion 7a of the locking convex portion 7 of the first case 4 and is held. As a result, the outer case 6 is attached to the outer peripheral portion 4a of the first case 4 without slipping out upward. In this state, the case packing 8 is arranged in a state of protruding upward in the packing groove 4c provided on the upper end surface of the first case 4. In this state, the second case 5 is arranged at the upper ends of the first case 4 and the outer case 6.

このときには、予め、第２ケース５内に見切り部材１３を上方から嵌め込むと共に、この見切り部材１３の上側に位置するように、第２ケース５内に時計ガラス１２をガラスパッキン１２ａと共に嵌め込む。この状態で、第１ケース４と外装ケース６との上端部に第２ケース５が配置されると、第２ケース５の位置規制部１４が第１ケース４の内周面に当接して第１ケース４内に嵌め込まれる。これにより、第２ケース５が第１ケース４の上端面に位置規制されて配置される。 At this time, the parting member 13 is fitted into the second case 5 from above, and the watch glass 12 is fitted into the second case 5 together with the glass packing 12a so as to be located above the parting member 13. In this state, when the second case 5 is arranged at the upper ends of the first case 4 and the outer case 6, the position regulating portion 14 of the second case 5 comes into contact with the inner peripheral surface of the first case 4, and the second case 5 is placed. It is fitted in one case 4. As a result, the second case 5 is positioned and arranged on the upper end surface of the first case 4.

また、このときには、第２ケース５の固定部１５が外装ケース６のバンド取付部２の取付突起部２ｂ上に配置されることにより、第２ケース５の切欠き部１５ａの下側の固定部１５が取付突起部２ｂの上端面の座面部２ｃに対応して配置される。このため、第２ケース５の固定部１５に設けられたねじ挿入孔１７が外装ケース６の取付突起部２ｂの座面部２ｃに設けられたねじ取付穴１８に同一軸上で対応する。 Further, at this time, the fixing portion 15 of the second case 5 is arranged on the mounting protrusion 2b of the band mounting portion 2 of the outer case 6, so that the fixing portion 15 on the lower side of the notch portion 15a of the second case 5 is arranged. 15 is arranged corresponding to the seating surface portion 2c of the upper end surface of the mounting projection portion 2b. Therefore, the screw insertion hole 17 provided in the fixing portion 15 of the second case 5 corresponds to the screw mounting hole 18 provided in the seat surface portion 2c of the mounting protrusion 2b of the outer case 6 on the same axis.

この状態で、第２ケース５を第１ケース４と外装ケース６との上端部にねじ部材１６によって取り付ける。このときには、ねじ部材１６のねじ部１６ｃをねじ挿入孔１７に上方から挿入させ、この挿入されたねじ部１６ｃをねじ取付穴１８に挿入させると共に、ねじ部材１６の首部１６ｂをねじ挿入孔１７とねじ取付穴１８の首挿入穴部１８ａとに挿入させて、頭部１６ａを第２ケース５の固定部１５上にこれを覆って配置されると共に、頭部１６ａの一部つまり半円部を切欠き部１５ａに配置させる。 In this state, the second case 5 is attached to the upper ends of the first case 4 and the outer case 6 by the screw member 16. At this time, the screw portion 16c of the screw member 16 is inserted into the screw insertion hole 17 from above, the inserted screw portion 16c is inserted into the screw mounting hole 18, and the neck portion 16b of the screw member 16 is inserted into the screw insertion hole 17. The head portion 16a is placed on the fixing portion 15 of the second case 5 by inserting it into the neck insertion hole portion 18a of the screw mounting hole 18, and a part of the head portion 16a, that is, a semicircular portion is placed. It is arranged in the notch portion 15a.

この状態で、ねじ部材１６のねじ部１６ｃをねじ取付穴１８のねじ穴部１８ｂに螺合させてねじ部材１６を締め付けると、ねじ部材１６の頭部１６ａが第２ケース５の固定部１５の上面にこれを覆って当接して、ねじ部１６ｃがねじ取付穴１８のねじ穴部１８ｂに螺入しながら外装ケース６を第２ケース５に引き寄せる。これにより、外装ケース６の係合凹部１０の下端部１０ａが第１ケース４の係止凸部７の下端部７ａを引き上げる。 In this state, when the screw portion 16c of the screw member 16 is screwed into the screw hole portion 18b of the screw mounting hole 18 to tighten the screw member 16, the head portion 16a of the screw member 16 becomes the fixing portion 15 of the second case 5. The outer case 6 is pulled to the second case 5 while the screw portion 16c is screwed into the screw hole portion 18b of the screw mounting hole 18 so as to cover and abut the upper surface. As a result, the lower end portion 10a of the engaging recess 10 of the outer case 6 pulls up the lower end portion 7a of the locking convex portion 7 of the first case 4.

この場合、ねじ部材１６、第２ケース５、第１ケース４、外装ケース６は、図４に２点鎖線で示す直線上にあり、平面視において重なる。すなわち、ねじ部材１６の頭部１６ａ、第２ケース５の固定部１５、第１ケース４の係止凸部７、外装ケース６の係合凹部１０の下端部１０ａは、その順で図４に２点鎖線で示す直線上において重なる。 In this case, the screw member 16, the second case 5, the first case 4, and the outer case 6 are on the straight line shown by the two-dot chain line in FIG. 4, and overlap in a plan view. That is, the head portion 16a of the screw member 16, the fixing portion 15 of the second case 5, the locking convex portion 7 of the first case 4, and the lower end portion 10a of the engaging recess 10 of the outer case 6 are shown in FIG. 4 in that order. It overlaps on the straight line indicated by the alternate long and short dash line.

このため、ねじ部材１６の頭部１６ａが第１ケース４の係止凸部７の上側に位置しているので、第２ケース５と第１ケース４とが確実に且つ強固に押え付けられる。これにより、第２ケース５、第１ケース４、外装ケース６が強固に取り付けられると共に、腕時計ケース１の小型化が図れる。 Therefore, since the head portion 16a of the screw member 16 is located above the locking convex portion 7 of the first case 4, the second case 5 and the first case 4 are reliably and firmly pressed against each other. As a result, the second case 5, the first case 4, and the outer case 6 can be firmly attached, and the wristwatch case 1 can be miniaturized.

このときには、第２ケース５の下端面が第１ケース４の上端面のパッキン溝４ｃに装着されたケースパッキン８を押し付けて圧縮変形させて、第２ケース５の下端面が第１ケース４の上端面に接近または接触して押し付けられる。これにより、第１ケース４の上端面と第２ケース５の下端面との間の防水がケースパッキン８によって図られて、気密性が確保される。また、このときには、第２ケース５が外装ケース６を介して第１ケース４に取り付けられる。 At this time, the lower end surface of the second case 5 presses the case packing 8 mounted on the packing groove 4c on the upper end surface of the first case 4 to compress and deform it, and the lower end surface of the second case 5 is the first case 4. It is pressed against or in contact with the upper end surface. As a result, waterproofing between the upper end surface of the first case 4 and the lower end surface of the second case 5 is achieved by the case packing 8, and airtightness is ensured. At this time, the second case 5 is attached to the first case 4 via the outer case 6.

また、この場合には、第１ケース４の上端面と第２ケース５の下端面とがケースパッキン８を圧縮変形させて接触または接近した状態で、第２ケース５の固定部１５が外装ケース６のバンド取付部２における取付突起部２ｂの上部に設けられた座面部２ｃに配置され、この状態で第２ケース５の固定部１５の下端面と座面部２ｃの座面との間に隙間Ｓが設けられる。 Further, in this case, the fixing portion 15 of the second case 5 is the outer case while the upper end surface of the first case 4 and the lower end surface of the second case 5 are in contact with or close to each other by compressing and deforming the case packing 8. It is arranged on the seat surface portion 2c provided above the mounting protrusion 2b in the band mounting portion 2 of No. 6, and in this state, a gap is provided between the lower end surface of the fixing portion 15 of the second case 5 and the seat surface of the seat surface portion 2c. S is provided.

このため、第２ケース５と外装ケース６とは、ねじ部材１６の締め付けによって取り付けられる際に、第２ケース５の固定部１５の下面と座面部２ｃの座面との間の隙間Ｓによって、ねじ部材１６が確実に締め付けられる。これにより、外装ケース６が第２ケース５に確実に引き寄せられて、第１ケース４が第２ケース５に強く押し付けられる。 Therefore, when the second case 5 and the outer case 6 are attached by tightening the screw member 16, the gap S between the lower surface of the fixing portion 15 of the second case 5 and the seating surface of the seating surface portion 2c causes the second case 5 and the outer case 6 to be attached. The screw member 16 is securely tightened. As a result, the outer case 6 is surely attracted to the second case 5, and the first case 4 is strongly pressed against the second case 5.

この場合、第２ケース５と外装ケース６とは、腕時計ケース１のバンド取付部２における対角線上、すなわち１時側の第２ケース５の固定部１５と７時側の第２ケース５の固定部１５との対角線上、および１１時側の第２ケース５の固定部１５と５時側の第２ケース５の固定部１５との対角線上において、ねじ部材１６が取り付けられていることにより、外装ケース６を介して第２ケース５が第１ケース４に確実に押し付けられる。 In this case, the second case 5 and the outer case 6 are fixed diagonally on the band mounting portion 2 of the wristwatch case 1, that is, the fixing portion 15 of the second case 5 on the 1 o'clock side and the second case 5 on the 7 o'clock side. The screw member 16 is attached on the diagonal line with the portion 15 and on the diagonal line between the fixing portion 15 of the second case 5 on the 11 o'clock side and the fixing portion 15 of the second case 5 on the 5 o'clock side. The second case 5 is securely pressed against the first case 4 via the outer case 6.

これにより、ケースパッキン８が第１ケース４の上端面と第２ケース５の下端面との間に強く挟まれて圧縮変形するので、第１ケース４の上端面と第２ケース５の下端面との間の防水が確実に図られると共に、第１ケース４が外装ケース６を介して第２ケース５に強固に取り付けられる。 As a result, the case packing 8 is strongly sandwiched between the upper end surface of the first case 4 and the lower end surface of the second case 5 and is compressed and deformed. Therefore, the upper end surface of the first case 4 and the lower end surface of the second case 5 are compressed. The first case 4 is firmly attached to the second case 5 via the outer case 6 while ensuring waterproofing between the two.

また、この腕時計ケース１は、第１ケース４にねじ部材１６が取り付けられるねじ取付穴１８が設けられていないので、第１ケース４の肉厚が薄く形成され、これにより腕時計ケース１全体の小型化が図られている。この場合、ねじ部材１６は、外装ケース６のバンド取付部２の取付突起部２ｂに取り付けられることにより、外装ケース６が第１ケース４の外周部４ａに装着されても、外装ケース６の外形が小さく抑えられ、これによっても腕時計ケース１全体の小型化が図られている。 Further, since the wristwatch case 1 is not provided with the screw mounting hole 18 for mounting the screw member 16 in the first case 4, the wall thickness of the first case 4 is formed to be thin, whereby the entire wristwatch case 1 is made smaller. Is being planned. In this case, the screw member 16 is attached to the attachment protrusion 2b of the band attachment portion 2 of the outer case 6, so that even if the outer case 6 is attached to the outer peripheral portion 4a of the first case 4, the outer shape of the outer case 6 is formed. Is kept small, and the size of the entire wristwatch case 1 is also reduced.

さらに、この腕時計ケース１は、第１ケース４が硬質の合成樹脂で形成され、この第１ケース４の外周部４ａがステンレスなどの金属製の外装ケース６で覆われ、第１ケース４の上部側がステンレスなどの金属製の第２ケース５で覆われているので、第１ケース４が外装ケース６と第２ケース５とによって確実に且つ良好に保護される。このため、腕時計ケース１が外部から衝撃を受けても、その衝撃によって第１ケース４が傷ついたり破損したりすることがない。 Further, in the wristwatch case 1, the first case 4 is formed of a hard synthetic resin, the outer peripheral portion 4a of the first case 4 is covered with a metal outer case 6 such as stainless steel, and the upper portion of the first case 4 is covered. Since the side is covered with the second case 5 made of metal such as stainless steel, the first case 4 is reliably and well protected by the outer case 6 and the second case 5. Therefore, even if the wristwatch case 1 receives an impact from the outside, the impact does not damage or damage the first case 4.

このように、この腕時計ケース１によれば、外周に係止凸部７が設けられた第１ケース４と、この第１ケース４の外周を覆い、且つ係止凸部７に係止される係合凹部１０を備えた外装部材である外装ケース６と、第１ケース４と外装ケース６との上部に配置される第２ケース５と、この第２ケース５を外装ケース６に締結して第２ケース５を第１ケース４に取り付ける締結部材であるねじ部材１６と、を備えていることにより、部品点数の削減を図ることができると共に、腕時計ケース１全体の小型化を図ることができる。 As described above, according to the wristwatch case 1, the first case 4 provided with the locking convex portion 7 on the outer periphery and the outer periphery of the first case 4 are covered and locked by the locking convex portion 7. An exterior case 6 which is an exterior member provided with an engaging recess 10, a second case 5 arranged above the first case 4 and the exterior case 6, and the second case 5 are fastened to the exterior case 6. By providing the screw member 16 which is a fastening member for attaching the second case 5 to the first case 4, the number of parts can be reduced and the entire wristwatch case 1 can be miniaturized. ..

It can be securely tightened and attached. As a result, the first case 4 can be securely pressed against the second case 5 and attached, and the case packing 8 can be reliably sandwiched between the first case 4 and the second case 5.

すなわち、この腕時計ケース１では、腕時計ケース１のバンド取付部２における対角線上、すなわち１時側の第２ケース５の固定部１５と７時側の第２ケース５の固定部１５との対角線上、および１１時側の第２ケース５の固定部１５と５時側の第２ケース５の固定部１５との対角線上において、ねじ部材１６が第２ケース５と外装ケース６とを締め付けて取りけることができるので、外装ケース６を介して第１ケース４を第２ケース５に効率良く確実に取り付けることができる。 That is, in the wristwatch case 1, on the diagonal line of the band mounting portion 2 of the wristwatch case 1, that is, on the diagonal line between the fixing portion 15 of the second case 5 on the 1 o'clock side and the fixing portion 15 of the second case 5 on the 7 o'clock side. , And the screw member 16 tightens the second case 5 and the outer case 6 on the diagonal line between the fixing portion 15 of the second case 5 on the 11 o'clock side and the fixing portion 15 of the second case 5 on the 5 o'clock side. Therefore, the first case 4 can be efficiently and reliably attached to the second case 5 via the outer case 6.

このため、この腕時計ケース１では、ねじ部材１６によるねじ止め個所を最小限に抑えることができるので、少ないねじ部材１６で外装ケース６を介して第１ケース４を第２ケース５に強固に取り付けることができると共に、ケースパッキン８を第１ケース４の上端面と第２ケース５の下端面との間に確実に挟むことができ、これにより第１ケース４と第２ケース５との間の防水を確実に図ることができる。 Therefore, in this wristwatch case 1, since the screwing portion by the screw member 16 can be minimized, the first case 4 is firmly attached to the second case 5 via the outer case 6 with a small number of screw members 16. In addition, the case packing 8 can be reliably sandwiched between the upper end surface of the first case 4 and the lower end surface of the second case 5, thereby between the first case 4 and the second case 5. Waterproofing can be ensured.

また、この腕時計ケース１では、第２ケース５の外側面にねじ部材１６の頭部１６ａが配置される切欠き部１５ａが固定部１５に対応して設けられていることにより、ねじ部材１６によって第１ケース４と第２ケース５とを取り付けた際に、ねじ部材１６の頭部１６ａによって第２ケース５の固定部１５を覆い隠することができると共に、頭部１６ａの一部を切欠き部１５ａに配置させることができるので、頭部１６ａが邪魔にならないばかりか、デザイン的に好ましいものを提供することができる。 Further, in the wristwatch case 1, a notch portion 15a in which the head portion 16a of the screw member 16 is arranged is provided on the outer surface of the second case 5 corresponding to the fixing portion 15, so that the screw member 16 provides the screw member 16. When the first case 4 and the second case 5 are attached, the fixed portion 15 of the second case 5 can be covered by the head 16a of the screw member 16, and a part of the head 16a is cut out. Since it can be arranged in the portion 15a, not only the head 16a does not get in the way, but also a design preferable one can be provided.

また、この腕時計ケース１では、ねじ部材１６、第２ケース５、第１ケース４、外装ケース６が、図４に２点鎖線で示す直線上にあり、平面視において重なっていることにより、第２ケース５、第１ケース４、外装ケース６を強固に取り付けることができる。すなわち、この腕時計ケース１では、ねじ部材１６の頭部１６ａ、第２ケース５の固定部１５、第１ケース４の係止凸部７、外装ケース６の係合凹部１０の下端部１０ａが、その順で直線上において重なっているので、ねじ部材１６の頭部１６ａを第１ケース４の係止凸部７の上側に位置させることができる。 Further, in the wristwatch case 1, the screw member 16, the second case 5, the first case 4, and the outer case 6 are on the straight line shown by the two-dot chain line in FIG. 4, and are overlapped in a plan view. The 2 case 5, the 1st case 4, and the outer case 6 can be firmly attached. That is, in the wristwatch case 1, the head portion 16a of the screw member 16, the fixing portion 15 of the second case 5, the locking convex portion 7 of the first case 4, and the lower end portion 10a of the engaging recess 10 of the outer case 6 are. Since they overlap in a straight line in that order, the head portion 16a of the screw member 16 can be positioned above the locking convex portion 7 of the first case 4.

これにより、この腕時計ケース１では、ねじ部材１６の頭部１６ａによって第２ケース５と第１ケース４とを確実に且つ強固に押え付けることができるので、第２ケース５、第１ケース４、外装ケース６を強固に取り付けることができると共に、腕時計ケース１の小型化を図ることができる。 As a result, in the wristwatch case 1, the second case 5 and the first case 4 can be reliably and firmly pressed by the head portion 16a of the screw member 16, so that the second case 5 and the first case 4 can be pressed. The outer case 6 can be firmly attached, and the wristwatch case 1 can be miniaturized.

さらに、この腕時計ケース１では、第１ケース４が合成樹脂によって形成され、外装ケース６と第２ケース５とが金属によって形成されていることにより、合成樹脂製の第１ケース４を金属製の外装ケース６と第２ケース５とによって確実に且つ良好に保護することができる。このため、腕時計ケース１が外部から衝撃を受けても、その衝撃によって第１ケース４が傷ついたり破損したりしないようにすることができる。 Further, in the wristwatch case 1, the first case 4 is made of synthetic resin, and the outer case 6 and the second case 5 are made of metal, so that the first case 4 made of synthetic resin is made of metal. The outer case 6 and the second case 5 can provide reliable and good protection. Therefore, even if the wristwatch case 1 receives an impact from the outside, the first case 4 can be prevented from being damaged or damaged by the impact.

なお、上述した実施形態では、第１ケース４の係止凸部７が第１ケース４の外周部４ａの外周面から外部に突出して設けられ、外装ケース６の係合凹部１０が外装ケース６の内周面に窪んで設けられ、係止凸部７が外装ケース６の上方から係合凹部１０に挿入して係合するように構成されている場合について述べたが、この発明は、これに限らず、例えば第１ケース４の外周部４ａの外面に係止凹部を設け、外装ケース６の内周面に係合凸部を設けた構造であっても良い。 In the above-described embodiment, the locking convex portion 7 of the first case 4 is provided so as to project outward from the outer peripheral surface of the outer peripheral portion 4a of the first case 4, and the engaging recess 10 of the outer case 6 is the outer case 6. The case where the locking convex portion 7 is provided by being recessed in the inner peripheral surface of the outer case 6 and is configured to be inserted into and engaged with the engaging concave portion 10 from above the outer case 6 has been described. However, the structure may be limited to, for example, a structure in which a locking recess is provided on the outer surface of the outer peripheral portion 4a of the first case 4 and an engaging convex portion is provided on the inner peripheral surface of the outer case 6.

この場合には、係止凹部を第１ケース４の外周部４ａにおける外面の中間部から下端部に亘って設け、係合凸部を外装ケース６の内周面における下部に設け、外装ケース６を第１ケース４の外周部４ａに取り付ける際に、外装ケース６の係合凸部を第１ケース４の下側から係止凹部に挿入させ、係合凸部の上端部を係止凹部の上端部に当接させて係合させるようにすれば良い。 In this case, a locking recess is provided from the middle portion to the lower end portion of the outer surface of the outer peripheral portion 4a of the first case 4, and an engaging convex portion is provided at the lower portion of the inner peripheral surface of the outer case 6, and the outer case 6 is provided. Is attached to the outer peripheral portion 4a of the first case 4, the engaging convex portion of the outer case 6 is inserted into the locking concave portion from the lower side of the first case 4, and the upper end portion of the engaging convex portion is inserted into the locking concave portion. It suffices to bring it into contact with the upper end portion and engage it.

また、上述した実施形態では、第１ケース４の上端面にパッキン溝４ｃを設け、このパッキン溝４ｃにケースパッキン８を装着した場合について述べたが、この発明は、これに限らず、例えば第２ケース５の下端面にパッキン溝を設け、このパッキン溝にケースパッキン８を装着するようにしても良い。 Further, in the above-described embodiment, the case where the packing groove 4c is provided on the upper end surface of the first case 4 and the case packing 8 is attached to the packing groove 4c has been described. However, the present invention is not limited to this, and for example, the first case. 2 A packing groove may be provided on the lower end surface of the case 5, and the case packing 8 may be mounted in the packing groove.

また、上述した実施形態では、ねじ部材１６が頭部１６ａと首部１６ｂとねじ部１６ｃとを備えている場合について述べたが、この発明は、これに限らず、ねじ部材１６が頭部とねじ部とを備えただけの構造であっても良い。この場合には、外装ケース６のねじ取付穴１８がねじ穴部１８ｂのみで形成されていても良い。 Further, in the above-described embodiment, the case where the screw member 16 includes the head portion 16a, the neck portion 16b, and the screw portion 16c has been described, but the present invention is not limited to this, and the screw member 16 has a head portion and a screw. The structure may be simply provided with a part. In this case, the screw mounting hole 18 of the outer case 6 may be formed only by the screw hole portion 18b.

また、上述した実施形態では、締結部材としてねじ部材１６を用いた場合について述べたが、この発明は、必ずしもねじ部材１６である必要はなく、第２ケース５を外装ケース６に押し当てように締結するものであれば、どのようなものであっても良い。 Further, in the above-described embodiment, the case where the screw member 16 is used as the fastening member has been described, but the present invention does not necessarily have to be the screw member 16, and the second case 5 is pressed against the outer case 6. Anything may be used as long as it is to be concluded.

また、上述した実施形態では、第１ケース４の肉厚が薄く形成されているので、外装ケース６を厚くして、外部から衝撃に対する腕時計ケース１の耐衝撃性を高めることもできる。 Further, in the above-described embodiment, since the wall thickness of the first case 4 is formed to be thin, the outer case 6 can be made thicker to improve the impact resistance of the wristwatch case 1 against an external impact.

さらに、上述した実施形態では、腕時計に適用した場合について述べたが、この発明は必ずしも腕時計である必要はなく、例えばトラベルウオッチ、目覚まし時計、置き時計、掛け時計などの各種の時計に適用することができる。また、この発明は、必ずしも時計である必要はなく、例えば携帯端末や携帯通信機などの電子機器にも適用することができる。 Further, in the above-described embodiment, the case where it is applied to a wristwatch has been described, but the present invention does not necessarily have to be a wristwatch, and can be applied to various clocks such as a travel watch, an alarm clock, a table clock, and a wall clock. .. Further, the present invention does not necessarily have to be a watch, and can be applied to electronic devices such as mobile terminals and mobile communication devices.
