すなわち、この内側蓋部12は、図6および図12に示すように、外側蓋部11の蓋装着凹部11cとほぼ同じ大きさに形成された板部12aと、この板部12aの周囲に垂下(図12では起立)された枠状部12bとを一体に形成し、板部12aと枠状部12bとが電池収納部8の開口部8a内に挿入するように構成されている。この場合、枠状部12bの外周部には、図12(a)〜図12(c)に示すように、パッキン溝18が内側蓋部12の外周に沿って環状に連続して設けられている。   That is, as shown in FIG. 6 and FIG. 12, the inner lid portion 12 hangs around a plate portion 12a formed substantially the same size as the lid mounting concave portion 11c of the outer lid portion 11, and around the plate portion 12a. The frame-like portion 12b (standing up in FIG. 12) is integrally formed, and the plate portion 12a and the frame-like portion 12b are configured to be inserted into the opening 8a of the battery housing portion 8. In this case, as shown in FIGS. 12A to 12C, packing grooves 18 are continuously provided in an annular shape along the outer periphery of the inner lid portion 12 on the outer peripheral portion of the frame-shaped portion 12 b. Yes.

このパッキン溝18は、図7〜図9、図12に示すように、内側蓋部12の外周面に形成された断面矩形状の凹部であり、内側蓋部12の外周側に向けて開放された状態で、外側蓋部11の一対の係合フック部13に対面して接近するように構成されている。また、このパッキン溝18は、図6、図8および図10に示すように、その内部に防水パッキン20が内側蓋部12の外周に沿って環状に連続した状態で装着されるように構成されている。   As shown in FIGS. 7 to 9 and FIG. 12, the packing groove 18 is a recess having a rectangular cross section formed on the outer peripheral surface of the inner lid portion 12, and is opened toward the outer peripheral side of the inner lid portion 12. In this state, the pair of engaging hook portions 13 of the outer lid portion 11 are configured to face each other and approach each other. Further, as shown in FIGS. 6, 8, and 10, the packing groove 18 is configured so that the waterproof packing 20 is attached in an annularly continuous state along the outer periphery of the inner lid portion 12. ing.

この防水パッキン20は、図13に示すように、ゴムなどの弾性部材からなり、断面がほぼ円形状に形成されている。この場合、防水パッキン20は、図8および図10に示すように、内側蓋部12のパッキン溝18内に配置された際に、その一部がパッキン溝18内から内側蓋部12の外周側の外部に突出するように、パッキン溝18の円周方向の深さよりも少し太く形成されている。   As shown in FIG. 13, the waterproof packing 20 is made of an elastic member such as rubber and has a substantially circular cross section. In this case, as shown in FIGS. 8 and 10, when the waterproof packing 20 is disposed in the packing groove 18 of the inner lid portion 12, a part of the waterproof packing 20 extends from the packing groove 18 to the outer peripheral side of the inner lid portion 12. The packing groove 18 is formed to be slightly thicker than the circumferential depth of the packing groove 18.

また、内側蓋部12の前後方向(つまり下部ケース3の長手方向)における一側部(図6では下辺部)、つまり外側蓋部11の固定溝部16と反対側に位置する側部には、図3、図5および図6に示すように、電池収納部8を電池蓋6で塞ぐ際に、電池蓋6の回転支点となる一対の支持突起21が側方(図6では手前側)に向けて突出して設けられている。   In addition, on one side portion (lower side portion in FIG. 6) in the front-rear direction of the inner lid portion 12 (that is, the longitudinal direction of the lower case 3), that is, on the side portion that is opposite to the fixed groove portion 16 of the outer lid portion 11, As shown in FIGS. 3, 5, and 6, when the battery housing portion 8 is closed with the battery lid 6, the pair of support protrusions 21 that serve as rotation fulcrums of the battery lid 6 are laterally (front side in FIG. 6). It is provided so as to protrude.

すなわち、この一対の支持突起21は、図10(a)および図10(b)に示すように、内側蓋部12の枠状部12bにおけるパッキン溝18よりも下側(図10では上側)に位置する外側面からその側方に突出して形成され、電池蓋6を電池収納部8に取り付ける際に、図4に示すように、電池収納部8の開口部8aの内周面に設けられた係止穴部22に挿脱可能に挿入して保持されるように構成されている。   That is, as shown in FIGS. 10A and 10B, the pair of support protrusions 21 are located below (upper in FIG. 10) the packing groove 18 in the frame-like portion 12b of the inner lid portion 12. When the battery cover 6 is attached to the battery housing portion 8, it is provided on the inner peripheral surface of the opening 8 a of the battery housing portion 8 when the battery lid 6 is attached to the battery housing portion 8. It is configured to be inserted and held in the locking hole portion 22 so as to be detachable.

これにより、電池蓋6は、図3および図4に示すように、電池収納部8を塞ぐ際に、内側蓋b12の外周部に設けられた一対の支持突起21を電池収納部8の係止穴部22に挿入させて保持させ、この状態で一対の支持突起21を中心に内側蓋部12を回転させると、内側蓋部12が電池収納部8の開口部8a内に挿入すると共に、外側蓋部11の湾曲部11bを含む外周縁部が電池収納部8の開口部8aの周囲に設けられた装着凹部8b内に配置されるように構成されている。   Thereby, as shown in FIGS. 3 and 4, when the battery cover 6 closes the battery storage part 8, the pair of support protrusions 21 provided on the outer peripheral part of the inner cover b <b> 12 are engaged with the battery storage part 8. When the inner lid 12 is rotated around the pair of support protrusions 21 in this state, the inner lid 12 is inserted into the opening 8a of the battery housing 8 and the outer lid 12 is inserted into the hole 22 and held in this state. The outer peripheral edge portion including the curved portion 11 b of the lid portion 11 is configured to be disposed in a mounting recess portion 8 b provided around the opening portion 8 a of the battery storage portion 8.

次に、このような電池蓋6を製作する場合について説明する。
この場合には、外側蓋部11と内側蓋部12とを別々に製作する。まず、外側蓋部11を製作する場合には、成形用の第1金型によって成形する。このとき、外側蓋部11の係合フック部13は、外側蓋部11の湾曲部11bから垂下(図11(b)では起立)され、その下端部(図11(b)では上端部)が外側蓋部11の中央部、つまり内側蓋部12の外周面に向けて突出した形状になっている。
Next, a case where such a battery lid 6 is manufactured will be described.
In this case, the outer lid portion 11 and the inner lid portion 12 are manufactured separately. First, when manufacturing the outer side cover part 11, it shape | molds with the 1st metal mold | die for shaping | molding. At this time, the engagement hook portion 13 of the outer lid portion 11 is suspended from the curved portion 11b of the outer lid portion 11 (standing up in FIG. 11B), and its lower end portion (upper end portion in FIG. 11B). The outer lid portion 11 has a shape protruding toward the central portion of the outer lid portion 11, that is, toward the outer peripheral surface of the inner lid portion 12.

また、この外側蓋部11の一側部(図11(c)では右側部)に位置する固定溝部16は、固定部材15の係止鍔部(図示せず)が挿脱可能に挿入する上下の挟持鍔部16a、16bが形成された形状になっている。これにより、外側蓋部11の係合フック部13および固定溝部16は、所謂アンダーカット形状またはオーバーハング形状になっている。   Further, the fixing groove portion 16 located on one side portion (the right side portion in FIG. 11C) of the outer lid portion 11 is an upper and lower portion into which a locking collar portion (not shown) of the fixing member 15 is removably inserted. The sandwiching hooks 16a and 16b are formed. Thereby, the engagement hook part 13 and the fixing groove part 16 of the outer side cover part 11 are what is called an undercut shape or an overhang shape.

このため、成形用の第1金型の内部には、係合フック部13および固定溝部16を形成するために、スライド機構が設けられている。これにより、外側蓋部11は、第1金型内に樹脂を射出させた後に離型する際に、スライド機構のスライドコアをスライドさせることにより、外側蓋部11に一体に成形される。   For this reason, a slide mechanism is provided in the first mold for molding in order to form the engagement hook portion 13 and the fixing groove portion 16. Thus, the outer lid portion 11 is formed integrally with the outer lid portion 11 by sliding the slide core of the slide mechanism when releasing the resin after injecting the resin into the first mold.

一方、内側蓋部12を成形する場合には、成形用の第2金型によって成形する。このときには、内側蓋部12の枠状部12bの外周面に沿って連続するパッキン溝18が、枠状部12bの外周面から外部側方に向けて開放された形状になっている。これにより、内側蓋部12のパッキン溝18も、アンダーカット形状またはオーバーハング形状になっている。このため、内側蓋部12を成形する成形用の第2金型内にも、パッキン溝18を形成するために、スライド機構が設けられている。これにより、内側蓋部12は、外側蓋部11と同様に、第2金型によって成形される。   On the other hand, when the inner lid portion 12 is molded, the inner lid portion 12 is molded by the second mold for molding. At this time, the packing groove 18 continuous along the outer peripheral surface of the frame-shaped portion 12b of the inner lid portion 12 has a shape opened from the outer peripheral surface of the frame-shaped portion 12b toward the outside. Thereby, the packing groove 18 of the inner side cover part 12 is also an undercut shape or an overhang shape. For this reason, a slide mechanism is provided in the second mold for molding the inner lid portion 12 in order to form the packing groove 18. As a result, the inner lid portion 12 is molded by the second mold in the same manner as the outer lid portion 11.

次に、外側蓋部11の内面に内側蓋部12を接着剤や溶着によって固定する。このときには、図6に示すように、外側蓋部11の内面に設けられた蓋装着凹部11c内に内側蓋部12の板部12aを配置して、内側蓋部12の一側部(図6では上辺部)を外側蓋部11の固定溝部16に接近させると共に、内側蓋部12の一対の支持突起21を外側蓋部11の他側部(図6では下辺部)から突出させる。   Next, the inner lid 12 is fixed to the inner surface of the outer lid 11 with an adhesive or welding. At this time, as shown in FIG. 6, the plate portion 12 a of the inner lid portion 12 is disposed in the lid mounting recess 11 c provided on the inner surface of the outer lid portion 11, and one side portion of the inner lid portion 12 (FIG. 6). Then, the upper side portion is brought close to the fixing groove portion 16 of the outer lid portion 11, and the pair of support protrusions 21 of the inner lid portion 12 are projected from the other side portion (lower side portion in FIG. 6).

この状態で、外側蓋部11の内面に内側蓋部12を固定すると、図6〜図8に示すように、外側蓋部11の一対の係合フック部13と内側蓋部12の枠状部12bのパッキン溝18とが、互いに対面した状態で接近する。この場合、外側蓋部11と内側蓋部12とを1つの成形用金型で一体に成形しようとすると、外側蓋部11の一対の係合フック部13と内側蓋部12の枠状部12bのパッキン溝18との間隔Sが狭いため、成形用金型内にスライド機構を設けることができない。   In this state, when the inner lid portion 12 is fixed to the inner surface of the outer lid portion 11, a pair of engaging hook portions 13 of the outer lid portion 11 and a frame-like portion of the inner lid portion 12 as shown in FIGS. The 12b packing grooves 18 approach each other while facing each other. In this case, when the outer lid portion 11 and the inner lid portion 12 are formed integrally with one molding die, the pair of engaging hook portions 13 of the outer lid portion 11 and the frame-like portion 12b of the inner lid portion 12 are used. Since the distance S between the first and second packing grooves 18 is narrow, a slide mechanism cannot be provided in the molding die.

しかし、この実施形態のように、外側蓋部11と内側蓋部12とを別々に成形することにより、外側蓋部11の一対の係合フック部13と内側蓋部12の枠状部12bのパッキン溝18との間隔Sが狭くても、外側蓋部11に内側蓋部12を固定するときに、その両者の間隔Sを調整することにより、狭い間隔Sに設定することができる。   However, as in this embodiment, by forming the outer lid portion 11 and the inner lid portion 12 separately, the pair of engaging hook portions 13 of the outer lid portion 11 and the frame-like portion 12b of the inner lid portion 12 are formed. Even when the gap S with the packing groove 18 is narrow, when the inner lid 12 is fixed to the outer lid 11, the gap S can be set to be narrow by adjusting the gap S between the two.

次に、このような電池蓋6を下部ケース3に取り付けて電池収納部8の開口部8aを塞ぐ場合について説明する。
このときには、まず、内側蓋部12の枠状部12bのパッキン溝18内に防水パッキン20を装着する。そして、図3および図4に示すように、電池蓋6の内側蓋部12を下部ケース3の電池収納部8の開口部8aに対応させて、内側蓋部12の一対の支持突起21を電池収納部8の係止穴部22(図4参照)に挿入する。
Next, a case where such a battery lid 6 is attached to the lower case 3 to close the opening 8a of the battery housing portion 8 will be described.
At this time, first, the waterproof packing 20 is mounted in the packing groove 18 of the frame-like portion 12 b of the inner lid portion 12. 3 and 4, the inner lid portion 12 of the battery lid 6 is made to correspond to the opening portion 8a of the battery housing portion 8 of the lower case 3, and the pair of support protrusions 21 of the inner lid portion 12 are connected to the battery. It inserts in the locking hole part 22 (refer FIG. 4) of the accommodating part 8. FIG.

この状態で、一対の支持突起21を中心に電池蓋6を回転させて、内側蓋部12を電池収納部8の開口部8a内に挿入すると共に、外側蓋部11の湾曲部11bを含む周縁部を電池収納部8の開口部8aの周囲に設けられた装着凹部8b内に配置する。このときには、内側蓋部12の外周面のパッキン溝18内に装着されて外部に突出した防水パッキン20の一部が、電池収納部8の開口部8aの内周面に弾接して密接する。これにより、内側蓋部12は、電池収納部8の開口部8a内に防水パッキン20の弾接によってガイドされながら挿入するので、電池蓋6全体をガイドする。   In this state, the battery lid 6 is rotated around the pair of support protrusions 21 to insert the inner lid portion 12 into the opening 8a of the battery housing portion 8 and the peripheral edge including the curved portion 11b of the outer lid portion 11. Are disposed in a mounting recess 8b provided around the opening 8a of the battery storage unit 8. At this time, a part of the waterproof packing 20 that is mounted in the packing groove 18 on the outer peripheral surface of the inner lid portion 12 and protrudes to the outside is brought into elastic contact with the inner peripheral surface of the opening 8 a of the battery storage unit 8. Thus, the inner lid 12 is inserted into the opening 8 a of the battery storage portion 8 while being guided by the elastic contact of the waterproof packing 20, so that the entire battery lid 6 is guided.

また、外側蓋部11の周縁部の湾曲部11bを含む周縁部が、電池収納部8の開口部8aの周囲に設けられた装着凹部8b内に配置すると、外側蓋部11の内面に設けられた一対の係合フック部13が、図3に示すように、電池収納部8の開口部8aの周縁部に設けられた装着凹部8bにおける下部ケース3の両側部に位置する箇所に設けられた一対の係止溝部14に係止される。これにより、電池蓋6が電池収納部8の開口部8aを塞いて電池収納部8を密閉した状態で、下部ケース3に取り付けられる。   Further, when the peripheral edge portion including the curved portion 11 b of the peripheral edge portion of the outer lid portion 11 is disposed in the mounting recess 8 b provided around the opening portion 8 a of the battery storage portion 8, the outer lid portion 11 is provided on the inner surface of the outer lid portion 11. As shown in FIG. 3, the pair of engaging hook portions 13 are provided at locations located on both sides of the lower case 3 in the mounting recess 8 b provided at the peripheral edge of the opening 8 a of the battery housing portion 8. Locked in the pair of locking grooves 14. Thereby, the battery lid 6 is attached to the lower case 3 in a state where the opening 8 a of the battery housing portion 8 is closed and the battery housing portion 8 is sealed.

すると、図2および図3に示すように、下部ケース3に設けられた固定部材15の円板部15aが外側蓋部11の一側部に設けられた半円形状の固定溝部16に相対的に挿入する。この状態で、円板部15aの上面に設けられた操作部15bを指で回して円板部15aを所定角度回転させると、円板部15aの係合鍔部(図示せず)が外側蓋部11の固定溝部16の上下の挟持鍔部16a、16b間に挿入する。これによっても、外側蓋部11が下部ケース3に固定される。   Then, as shown in FIGS. 2 and 3, the disk portion 15 a of the fixing member 15 provided in the lower case 3 is relative to the semicircular fixing groove portion 16 provided in one side portion of the outer lid portion 11. Insert into. In this state, when the operating portion 15b provided on the upper surface of the disc portion 15a is turned with a finger to rotate the disc portion 15a by a predetermined angle, the engaging collar portion (not shown) of the disc portion 15a becomes the outer lid. It is inserted between the upper and lower clamping flange portions 16a and 16b of the fixed groove portion 16 of the portion 11. This also fixes the outer lid portion 11 to the lower case 3.

この結果、電池蓋6は、下部ケース3の一対の係止溝部14に対する一対の係合フック部13の係合、電池収納部8の開口部8aの係止穴部22に対する一対の支持突起21の挿入保持、および固定部材15による固定溝部16の固定によって、下部ケース3に対し確実に且つ強固に取り付けられる。なお、電池蓋6を取り外す場合には、上述した操作と逆の操作を行うことにより、容易に取り外すことができる。   As a result, the battery cover 6 has a pair of support protrusions 21 for the engagement of the pair of engagement hook portions 13 with the pair of engagement groove portions 14 of the lower case 3 and the engagement hole portion 22 of the opening 8 a of the battery storage portion 8. By being inserted and held, and by fixing the fixing groove 16 by the fixing member 15, it is securely and firmly attached to the lower case 3. In addition, when removing the battery cover 6, it can remove easily by performing operation reverse to the operation mentioned above.

このように、この電池蓋6によれば、下部ケース3の外形の一部を形成する外側蓋部11と、この外側蓋部11の内側に取り付けられて電池収納部8の開口部8aに挿脱可能に挿入する内側蓋部12とを備え、外側蓋部11の内面には、電池収納部8の両側に位置する下部ケース3の外側部にそれぞれ設けられた一対の係止溝部14に係脱可能に係合する一対の係合フック部13が形成されており、内側蓋部12の外周部には、外側蓋部11の一対の係合フック部13に対面した状態で接近するパッキン溝18が、全周に沿って連続して形成されている構成であるから、構造が簡単で、容易に製作できると共に、防水性を確保することができる。   As described above, according to the battery lid 6, the outer lid portion 11 that forms a part of the outer shape of the lower case 3 and the opening 8 a of the battery housing portion 8 that is attached to the inner side of the outer lid portion 11 are inserted. An inner lid portion 12 that is removably inserted, and the inner surface of the outer lid portion 11 is engaged with a pair of locking groove portions 14 respectively provided on the outer side portions of the lower case 3 located on both sides of the battery housing portion 8. A pair of engaging hook portions 13 that are detachably engaged are formed, and a packing groove that approaches the outer peripheral portion of the inner lid portion 12 while facing the pair of engaging hook portions 13 of the outer lid portion 11. Since 18 is a structure formed continuously along the entire circumference, the structure is simple and can be easily manufactured, and waterproofness can be ensured.

すなわち、この電池蓋6では、下部ケース3の電池収納部8を塞ぐ際に、外側蓋部11の内面に固定された内側蓋部12のパッキン溝18に防水パッキン20を装着し、この内側蓋部11を下部ケース3の電池収納部8の開口部8aに挿入させて、外側蓋部11を下部ケース3に押し付けると、電池収納部8の開口部8aの内周面に防水パッキン20を密接させて外側蓋部11の一対の係合フック部13を下部ケース3の両側の外側部に設けられた一対の係止溝部14に係合させることができる。   That is, in the battery lid 6, when the battery housing portion 8 of the lower case 3 is closed, the waterproof packing 20 is attached to the packing groove 18 of the inner lid portion 12 fixed to the inner surface of the outer lid portion 11. When the portion 11 is inserted into the opening 8 a of the battery housing portion 8 of the lower case 3 and the outer lid portion 11 is pressed against the lower case 3, the waterproof packing 20 is brought into close contact with the inner peripheral surface of the opening 8 a of the battery housing portion 8. Thus, the pair of engaging hook portions 13 of the outer lid portion 11 can be engaged with the pair of locking groove portions 14 provided on the outer side portions on both sides of the lower case 3.

この場合、電池蓋6は、外側蓋部11の係合フック部13と内側蓋部12の枠状部12bに設けられたパッキン溝18とが対面した状態で接近した構成であるから、下部ケース3の係止溝部14に外側蓋部11の係合フック部13が係合した際に、下部ケース3の係止溝部14に対する係合フック部13の係合力によって、パッキン溝18に装着された防水パッキン20を電池収納部8の内周面に確実に且つ強固に押し付けることができ、これにより防水性を高めることができる。   In this case, since the battery cover 6 is configured such that the engagement hook part 13 of the outer cover part 11 and the packing groove 18 provided in the frame-like part 12b of the inner cover part 12 face each other, the lower case When the engaging hook portion 13 of the outer lid portion 11 is engaged with the engaging groove portion 14 of the outer lid 11, the engaging hook portion 13 is engaged with the engaging groove portion 14 of the lower case 3 and is attached to the packing groove 18. The waterproof packing 20 can be reliably and firmly pressed against the inner peripheral surface of the battery housing portion 8, thereby improving the waterproof property.

このため、1つの防水パッキン20を内側蓋部12のパッキン溝18に装着するだけの簡単な構造で、防水性を確保することができると共に、下部ケース3の係止溝部14に外側蓋部11の係合フック部13を係合させるだけで、簡単に且つ確実に電池蓋6を下部ケース3に取り付けることができる。これにより、防水パッキン20を電池収納部8の内周面に確実に且つ良好に押し付けることができるので、防水性を確実に維持することができる。   Therefore, the waterproof structure can be secured with a simple structure in which one waterproof packing 20 is simply mounted in the packing groove 18 of the inner lid portion 12, and the outer lid portion 11 is provided in the locking groove portion 14 of the lower case 3. The battery cover 6 can be attached to the lower case 3 simply and securely by simply engaging the engaging hook portion 13. Thereby, the waterproof packing 20 can be reliably and satisfactorily pressed against the inner peripheral surface of the battery housing portion 8, so that the waterproof property can be reliably maintained.

また、外側蓋部1と内側蓋部12とを別々に成形することができるので、外側蓋部11の係合フック部13と内側蓋部12の枠状部12bに設けられたパッキン溝18とが対面した状態で接近する構成であっても、簡単に且つ容易に製作することができると共に、外側蓋部11と内側蓋部12とを自由な形状に形成することができ、これにより外観性およびデザイン性に優れたものを得ることができるほか、機器ケース1を握り易くすることができ、使い勝手が良く、且つ小型化および薄型化をも図ることができる。   Further, since the outer lid portion 1 and the inner lid portion 12 can be formed separately, the engagement hook portion 13 of the outer lid portion 11 and the packing groove 18 provided in the frame-like portion 12b of the inner lid portion 12 Even if it is the structure which approaches in the state which faced, while being able to manufacture easily and easily, the outer side cover part 11 and the inner side cover part 12 can be formed in a free shape, and, thereby, external appearance property In addition to being able to obtain an excellent design, the device case 1 can be easily grasped, it is easy to use, and it can be reduced in size and thickness.

この場合、外側蓋部11の係合フック部13は、内側蓋部12の外周側に位置して、内側蓋部12のパッキン溝18に向けて突出しており、内側蓋部12のパッキン溝18は、内側蓋部12の外周面から外部側方に向けて開放された状態で、係合フック部13に対面して接近していることにより、電池蓋6によって電池収納部8を塞いだ際に、パッキン溝18に装着された防水パッキン20を電池収納部8の開口部8aの内周面に確実に且つ良好に押し付けることができる。   In this case, the engagement hook portion 13 of the outer lid portion 11 is located on the outer peripheral side of the inner lid portion 12 and protrudes toward the packing groove 18 of the inner lid portion 12, and the packing groove 18 of the inner lid portion 12. When the battery housing portion 8 is closed by the battery lid 6 by being close to the engaging hook portion 13 while being opened from the outer peripheral surface of the inner lid portion 12 toward the outer side. In addition, the waterproof packing 20 mounted in the packing groove 18 can be reliably and satisfactorily pressed against the inner peripheral surface of the opening 8 a of the battery housing portion 8.

すなわち、外側蓋部11の係合フック部13と内側蓋部12のパッキン溝18とが互いに対面した状態で接近していることにより、下部ケース3の係止溝部14に外側蓋部11の係合フック部13が係合した際に、下部ケース3の係止溝部14に対する係合フック部13の係合力によって、パッキン溝18に装着された防水パッキン20を電池収納部8の内周面に確実に且つ強固に押し付けることができ、これにより、より一層、防水性を高めることができる。   In other words, the engagement hook portion 13 of the outer lid portion 11 and the packing groove 18 of the inner lid portion 12 approach each other so that the engagement of the outer lid portion 11 with the locking groove portion 14 of the lower case 3 is achieved. When the mating hook portion 13 is engaged, the waterproof packing 20 mounted in the packing groove 18 is applied to the inner peripheral surface of the battery housing portion 8 by the engaging force of the engaging hook portion 13 with the locking groove portion 14 of the lower case 3. It can be surely and firmly pressed, whereby the waterproofness can be further enhanced.
