Description

本発明は、例えば電子機器に搭載される電池を固定する搭載物固定構造に関する。   The present invention relates to a load fixing structure for fixing, for example, a battery mounted on an electronic device.

電池を搭載する電子機器は、基本的に、搭載した電池の上面から被せられるカバーにより固定される。例えば携帯電話機は、フロントケースに設けられた搭載部に電池が搭載され、その上面から電池カバーが被せられる。電池カバーは、主としてリアケース、フロントケースおよび／または電池カバーに設けられた嵌合、係合手段によって、フロントケースおよびリアケースに固定される。   An electronic device on which a battery is mounted is basically fixed by a cover that covers the upper surface of the mounted battery. For example, in a mobile phone, a battery is mounted on a mounting portion provided in a front case, and a battery cover is covered from the upper surface. The battery cover is fixed to the front case and the rear case mainly by fitting and engaging means provided on the rear case, the front case and / or the battery cover.

しかし、これらの部品間は嵌合させる際、必ずガタツキやキシミ等の原因となる隙間が空いてしまう。特にフロントケースおよび電池カバーについては、ユーザーが携帯電話機を使用する際には必ず接触する部分であり、ガタツキやキシミに繋がり易い。そこで、近年、電池を固定する為に適した様々な固定構造が考案されている。   However, when these parts are fitted together, there is always a gap that causes backlash and creaking. In particular, the front case and the battery cover are parts that are in contact with each other when the user uses the mobile phone, and are easily connected to rattling and creaking. Therefore, in recent years, various fixing structures suitable for fixing the battery have been devised.

例えば、特許文献１には、ケース側面に形成される嵌合凹部の構造を突起部およびリブにすることにより、内部スペースの利用が可能になり設置スペースを効率よく改善することができるとともに、電子機器のケース全体を小型化することができるバッテリー収納部構造が記載されている。当該バッテリー収納部構造では、カバーの突起部がリブに沿って案内されてケースにスライド嵌合するように設けているため、この突起部がカバーの左右方向のガタ付きを効果的に防止できるように構成されている。   For example, in Patent Document 1, the structure of the fitting recess formed on the side surface of the case is a protrusion and a rib, so that the internal space can be used and the installation space can be improved efficiently. A battery housing structure is described that can reduce the overall size of the device case. In the battery housing structure, since the protrusion of the cover is guided along the rib and is slidably fitted to the case, the protrusion can effectively prevent the cover from being rattled in the left-right direction. It is configured.

また、特許文献２では、ケースに対するカバーのガタツキを防止し、ケースの表面とカバーの表面との段差を解消することができるバッテリカバーのガタツキ防止構造が提案されている。当該ガタツキ防止構造では、バッテリ収納部を形成するケースの相対向する周壁の上面に先端部近傍にテーパ溝部を有する嵌合溝を形成し、カバーの相対向する周壁の下面には嵌合溝に適合するリブを設け、このリブを嵌合溝に沿ってスライドさせ、かつ先端のテーパ溝部に圧入させて嵌合するようにしている。   Further, Patent Document 2 proposes a battery cover rattling prevention structure that can prevent backlash of the cover with respect to the case and eliminate a step between the surface of the case and the surface of the cover. In the rattling prevention structure, a fitting groove having a tapered groove portion is formed in the vicinity of the tip portion on the upper surface of the facing peripheral wall of the case forming the battery housing portion, and the fitting groove is formed on the lower surface of the facing peripheral wall of the cover. A fitting rib is provided, and the rib is slid along the fitting groove and fitted into the tapered groove at the tip.

特開２０００−２６０４０６号公報JP 2000-260406 A 特開２００１−１１８５５５号公報JP 2001-118555 A

しかし、前述した特許文献１に記載のバッテリー収納部構造では、内部スペースの利用が可能になり設置スペースを効率よく改善する分、当該電池収納部構造が複雑となってしまい、製造コストも高くつくことが予想される。   However, in the battery storage unit structure described in Patent Document 1 described above, the internal space can be used and the installation space is efficiently improved, so that the battery storage unit structure becomes complicated and the manufacturing cost is high. It is expected that.

さらに、特許文献１に記載のバッテリー収納部構造、および、特許文献２に記載のバッテリカバーのガタツキ防止構造のいずれも、充分に電池カバーのガタツキおよびキシミを防止できるとは言い難い。というのは、いずれの構造においても、バッテリ収納部の周壁上面の溝の幅が、カバーの周壁下面のリブの幅よりも大きいという条件のみで嵌合するように形成されているからである。   Furthermore, it is difficult to say that both the battery housing structure described in Patent Document 1 and the battery cover rattling prevention structure described in Patent Document 2 can sufficiently prevent the battery cover from rattling and creaking. This is because, in any structure, the groove is formed on the upper surface of the peripheral wall of the battery storage portion so as to be fitted only on the condition that the width of the rib on the lower surface of the peripheral wall of the cover is larger.

併せて、固定手段として一般的である、リアカバーと電池カバーとの爪係合についても、通常の携帯電話機使用時に電池カバーが容易に外れてしまわないよう、最低限の保持力と着脱容易性とのバランスが必要である。   At the same time, with regard to the claw engagement between the rear cover and the battery cover, which is a general fixing means, the minimum holding force and ease of attachment and detachment are ensured so that the battery cover does not easily come off when using a normal mobile phone. Balance is necessary.

本発明は上記事情に鑑みてなされたものであり、構造が複雑となりすぎず、充分にカバーのガタツキおよびキシミの発生を抑制させ、かつ、カバーにおける爪の係合力を高めることが可能な搭載物固定構造の提供を目的とする。   The present invention has been made in view of the above circumstances, and is a mounted object capable of sufficiently suppressing the occurrence of backlash and creaking of the cover and increasing the engaging force of the claws in the cover without being too complicated in structure. The purpose is to provide a fixed structure.

以下、本発明の実施の形態について図面を参照しながら詳細に説明する。図中同一または相当部分には同一符号を付す。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

（実施の形態１）
図１は、本発明の実施の形態１に係る電池固定構造を利用する携帯電話機の構成例を示す概略図である。携帯電話機１の電池固定構造は、電池カバー２と、ケース部材３と、ケース部材３に収納される電池１２とから構成されている。 (Embodiment 1)
FIG. 1 is a schematic diagram showing a configuration example of a mobile phone using the battery fixing structure according to Embodiment 1 of the present invention. The battery fixing structure of the cellular phone 1 includes a battery cover 2, a case member 3, and a battery 12 accommodated in the case member 3.

なお、通常の携帯電話機１のケース部材３は、フロントケースおよびリアケースに分けられ、電池１２はフロントケースに収納される。リアケースの内部にはプリント基板等が実装されているが、本実施の形態１に係る電池固定構造には関係ない為省略する。その他、後述する図中に記載されている携帯電話機１における詳細な要素においても、本実施の形態１に係る電池固定構造に関係ない要素の説明を省略する。   In addition, the case member 3 of the normal mobile phone 1 is divided into a front case and a rear case, and the battery 12 is stored in the front case. A printed circuit board or the like is mounted inside the rear case, but is omitted because it is not related to the battery fixing structure according to the first embodiment. In addition, in the detailed elements of the cellular phone 1 described in the drawings to be described later, the description of the elements not related to the battery fixing structure according to the first embodiment is omitted.

本明細書において、電池カバー２の表面および裏面、ならびに、ケース部材３の表面および裏面という表現は、それぞれ図１に示す方向の面を意味する。すなわち、電池カバー２をケース部材３へ装着した際、電池カバー２の裏面およびケース部材３の表面は電池１２に近接した方の面を意味し、電池カバー２の表面およびケース部材３の裏面は電池１２から離れた方の外側の面を意味する。   In the present specification, expressions of the front and back surfaces of the battery cover 2 and the front and back surfaces of the case member 3 mean surfaces in the direction shown in FIG. That is, when the battery cover 2 is attached to the case member 3, the back surface of the battery cover 2 and the surface of the case member 3 mean the surface closer to the battery 12, and the surface of the battery cover 2 and the back surface of the case member 3 are It means the outer surface away from the battery 12.

図２は、実施の形態１に係る電池カバーの構成例を示す裏面図である。図１および図２に示すように、電池カバー２は、カバー天面４および相対向する二つのカバー側面５が一体に形成された構造となっている。また、爪部６および二つの線状の凸部７についても、カバー天面４と一体に形成されている。   FIG. 2 is a back view showing a configuration example of the battery cover according to the first embodiment. As shown in FIGS. 1 and 2, the battery cover 2 has a structure in which a cover top surface 4 and two opposite cover side surfaces 5 are integrally formed. Further, the claw portion 6 and the two linear convex portions 7 are also formed integrally with the cover top surface 4.

爪部６は、電池カバー２の周縁の一端に形成されている。凸部７は、電池カバー２の裏面から突出して、二つのカバー側面５から一定の間隔をおき、それぞれが相対向するように形成されている。また、好ましくは電池カバー２全体が弾性を有する材料によって形成されている。   The claw portion 6 is formed at one end of the peripheral edge of the battery cover 2. The convex part 7 protrudes from the back surface of the battery cover 2 and is formed so as to be opposed to each other with a certain distance from the two cover side surfaces 5. Preferably, the entire battery cover 2 is formed of a material having elasticity.

ケース部材３は、電池１２が収納される電池収納部８（図４参照）と、爪係止部９と、二つの線状の周壁１０とを備える。爪係止部９は、電池カバー２をケース部材３へ装着した際に、前述した電池カバー２の爪部６と係合する位置および形状に形成されている。二つの周壁１０は、ケース部材３の表面に相対向するよう形成されており、表面には同様に相対向するように線状の凹部１１が形成されている。   The case member 3 includes a battery storage portion 8 (see FIG. 4) in which the battery 12 is stored, a claw locking portion 9, and two linear peripheral walls 10. The claw locking portion 9 is formed at a position and shape that engages with the claw portion 6 of the battery cover 2 described above when the battery cover 2 is mounted on the case member 3. The two peripheral walls 10 are formed so as to face each other on the surface of the case member 3, and linear concave portions 11 are formed on the surface so as to face each other in the same manner.

電池カバー２を、電池１２が収納されたケース部材３に装着する動作について説明する。図１中の矢印に示すように、まず、電池カバー２を、ケース部材３の表面側から被せる。この際、電池カバー２の凸部７を、ケース部材３の凹部１１に嵌合させるように被せる。なお、凸部７および凹部１１は、それぞれが嵌合するような位置および形状に予め設計しておく。   An operation of attaching the battery cover 2 to the case member 3 in which the battery 12 is accommodated will be described. As shown by the arrow in FIG. 1, first, the battery cover 2 is covered from the surface side of the case member 3. At this time, the convex portion 7 of the battery cover 2 is covered with the concave portion 11 of the case member 3. In addition, the convex part 7 and the recessed part 11 are designed beforehand in the position and shape which each fit.

次に、電池カバー２（またはケース部材３）を、ケース部材３の凹部１１に沿って爪係止部９が形成されている方向にスライドさせ、爪部６と爪係止部９とを係合させることにより、装着する。なお、このような、凹形状を凸形状と嵌合し、その後スライドさせ、爪で係止するという固定方法は、当該分野の当業者にとっては公知の方法である（特許文献１および２参照）。従って、凹形状および凸形状、ならびに爪形状および爪係止形状の設計方法については、詳細を記載しなくとも当業者であれば容易に製造することが可能である。   Next, the battery cover 2 (or the case member 3) is slid along the concave portion 11 of the case member 3 in the direction in which the claw locking portion 9 is formed, and the claw portion 6 and the claw locking portion 9 are engaged. Wear them together. Such a fixing method of fitting the concave shape with the convex shape and then sliding and locking with the claw is a method known to those skilled in the art (see Patent Documents 1 and 2). . Therefore, those skilled in the art can easily manufacture the concave shape and the convex shape, and the design method of the nail shape and the nail locking shape without describing details.

図３は、実施の形態１に係る電池固定構造において、電池カバー装着後の構成例を示す表面図である。図４は、図３のＡ−Ａ線で切断した実施の形態１に係る電池固定構造を示す断面図である。さらに、図５は、図４のＸ部分における凹部と凸部との嵌合構造を示す拡大断面図である。   FIG. 3 is a surface view showing a configuration example after the battery cover is mounted in the battery fixing structure according to the first embodiment. 4 is a cross-sectional view showing the battery fixing structure according to Embodiment 1 cut along line AA in FIG. Further, FIG. 5 is an enlarged cross-sectional view showing a fitting structure between the concave portion and the convex portion in the portion X of FIG.

図５に示すように、凹部１１の幅ａは、凸部７の幅ｂよりも大きくなっている。図６は、実施の形態１に係る電池固定構造における爪部と爪係止部との係合構造を示す、図３のＢ−Ｂ線で切断した拡大断面図である。図４および図６の矢印については後に説明する。   As shown in FIG. 5, the width a of the concave portion 11 is larger than the width b of the convex portion 7. 6 is an enlarged cross-sectional view taken along the line B-B in FIG. 3, showing an engagement structure between the claw portion and the claw locking portion in the battery fixing structure according to the first embodiment. The arrows in FIGS. 4 and 6 will be described later.

本実施の形態１に係る電池固定構造では、図３ないし図５に示すように、電池カバー２をケース部材３に装着した際、凸部７は、側面において凹部１１の相対向する外側の内面（図５に示すＹ）に接触し、軽圧入となって嵌合している。これは、前述した凸部７および凹部１１の位置および形状の設計により、このような嵌合状態になるよう予め設計しておくことによる。また、図４および図５に示すように、周壁１０の形状は、電池カバー２のカバー天面４およびカバー側面５に適合するような形状、ずなわちオフセットされる形状となっている。   In the battery fixing structure according to the first embodiment, as shown in FIGS. 3 to 5, when the battery cover 2 is attached to the case member 3, the convex portion 7 has an inner surface on the outer side opposite to the concave portion 11. (Y shown in FIG. 5) and is fitted with light press-fitting. This is because it is designed in advance so as to be in such a fitting state by designing the positions and shapes of the convex portions 7 and the concave portions 11 described above. As shown in FIGS. 4 and 5, the shape of the peripheral wall 10 is a shape that fits the cover top surface 4 and the cover side surface 5 of the battery cover 2, that is, a shape that is offset.

凸部７が凹部１１に軽圧入される状態で嵌合される為、図４の矢印に示すように、電池収納部８（または電池１２）に向かって常に力が働いた状態で、電池カバー２およびケース部材３が装着されることになる。そのため、カバー側面５は、電池収納部８（または電池１２）側に向かって引き込まれ、ケース部材３との隙間が少なくなる。また、図４に示すように上向きの矢印の方向にも力が働くため、電池カバー２が膨らむような状態となる。その結果、図６の矢印に示すように、爪部６と爪係止部９との係合状態も強くなる。   Since the convex portion 7 is fitted in a state where it is lightly press-fitted into the concave portion 11, as shown by the arrow in FIG. 4, the battery cover is in a state where a force is always applied toward the battery housing portion 8 (or the battery 12). 2 and the case member 3 are mounted. Therefore, the cover side surface 5 is drawn toward the battery housing portion 8 (or the battery 12), and the gap with the case member 3 is reduced. Further, as shown in FIG. 4, since the force also works in the direction of the upward arrow, the battery cover 2 is in a state of swelling. As a result, as shown by the arrow in FIG. 6, the engagement state between the claw portion 6 and the claw locking portion 9 is also strengthened.

このような力が働くため、本実施の形態１の電池固定構造では、充分に電池カバー２のガタツキおよびキシミの発生を抑制させ、かつ、電池カバー２における爪部６の係合力を高めることが可能となる。また、構造が複雑になりすぎず、製造コストが高くなることはない。   Since such a force works, in the battery fixing structure of the first embodiment, it is possible to sufficiently suppress the backlash and creaking of the battery cover 2 and increase the engaging force of the claw portion 6 in the battery cover 2. It becomes possible. Further, the structure is not excessively complicated and the manufacturing cost is not increased.

（実施の形態２）
本実施の形態２では、前述した実施の形態１と、電池カバー２の凸部７の形状が異なる場合について述べる。その他の詳細な構成については、前述した実施の形態１と同様である。 (Embodiment 2)
In the second embodiment, a case where the shape of the convex portion 7 of the battery cover 2 is different from the first embodiment described above will be described. Other detailed configurations are the same as those in the first embodiment.

図７は、本発明の実施の形態２に係る凹部と凸部との嵌合構造を示す拡大断面図である。すなわち、電池カバー２をケース部材３に装着した状態における、周壁１０周辺の拡大断面図である。   FIG. 7 is an enlarged cross-sectional view showing a fitting structure between a concave portion and a convex portion according to Embodiment 2 of the present invention. That is, it is an enlarged cross-sectional view around the peripheral wall 10 in a state where the battery cover 2 is attached to the case member 3.

図７に示すとおり、本実施の形態２では、電池カバー２の凸部７の形状が、先端に向かって幅が漸減するテーパ構造となっている。しかし、実施の形態１と同様に、凸部７の少なくとも一部において凹部１１の相対向する外側の内面（図７に示すＹ）に接触し、軽圧入となって嵌合している。すなわち、実施の形態１において述べた電池固定構造に働く力と同様の力が働く。   As shown in FIG. 7, in the second embodiment, the shape of the convex portion 7 of the battery cover 2 has a taper structure in which the width gradually decreases toward the tip. However, as in the first embodiment, at least a part of the convex portion 7 is in contact with the inner surface (Y shown in FIG. 7) of the concave portion 11 facing each other and is lightly press-fitted. That is, the same force as that acting on the battery fixing structure described in the first embodiment works.

このように、本実施の形態２の電池固定構造によれば、実施の形態１と同様に、充分に電池カバー２のガタツキおよびキシミの発生を抑制させ、かつ、電池カバー２における爪部６の係合力を高めることが可能となる。また、構造が複雑となりすぎず、製造コストが高くなることはない。さらに、凸部７の端部がテーパ構造となっているので、ケース部材３の凹部１１と嵌合させるための組み込みが容易となる。   Thus, according to the battery fixing structure of the second embodiment, as in the first embodiment, the occurrence of rattling and creaking of the battery cover 2 is sufficiently suppressed, and the claw portion 6 of the battery cover 2 is The engagement force can be increased. Further, the structure is not too complicated and the manufacturing cost is not increased. Furthermore, since the end portion of the convex portion 7 has a tapered structure, it is easy to incorporate it into the concave portion 11 of the case member 3.

（実施の形態３）
本実施の形態３では、前述した実施の形態１と、電池カバー２の凸部７の形状が異なる場合について述べる。その他の詳細な構成については、前述した実施の形態１と同様である。 (Embodiment 3)
In the third embodiment, a case where the shape of the convex portion 7 of the battery cover 2 is different from that of the first embodiment described above will be described. Other detailed configurations are the same as those in the first embodiment.

図８は、本発明の実施の形態３に係る凹部と凸部との嵌合構造を示す拡大断面図である。すなわち、電池カバー２をケース部材３に装着した状態における、周壁１０周辺の拡大断面図である。   FIG. 8 is an enlarged cross-sectional view showing a fitting structure between a concave portion and a convex portion according to Embodiment 3 of the present invention. That is, it is an enlarged cross-sectional view around the peripheral wall 10 in a state where the battery cover 2 is attached to the case member 3.

図８に示すとおり、本実施の形態３では、電池カバー２の凸部７が、先端に突起部１３が形成された形状となっている。なお、突起部１３は、相対向する外側の内面（図８に示すＹ）に向かって突出している。そのため、凸部７は、突起部１３において図８に示すＹの面に接触し、軽圧入となって嵌合している。すなわち、実施の形態１において述べた電池固定構造に働く力と同様の力が働く。   As shown in FIG. 8, in the third embodiment, the convex portion 7 of the battery cover 2 has a shape in which a protruding portion 13 is formed at the tip. In addition, the protrusion part 13 protrudes toward the inner surface (Y shown in FIG. 8) on the opposite side. Therefore, the convex part 7 contacts the surface of Y shown in FIG. That is, the same force as that acting on the battery fixing structure described in the first embodiment works.

このように、本実施の形態３の電池固定構造によれば、実施の形態１と同様に、充分に電池カバー２のガタツキおよびキシミの発生を抑制させ、かつ、電池カバー２における爪部６の係合力を高めることが可能となる。また、構造が複雑になりすぎず、製造コストが高くなることはない。さらに、凸部７が先端に突起部１３が形成された形状であるため、凸形状を撓ませ易くさせることが可能となり、仕様に応じた嵌合力の調整が可能となる。   Thus, according to the battery fixing structure of the third embodiment, as in the first embodiment, the occurrence of rattling and creaking of the battery cover 2 is sufficiently suppressed, and the claw portion 6 of the battery cover 2 is The engagement force can be increased. Further, the structure is not excessively complicated and the manufacturing cost is not increased. Furthermore, since the convex portion 7 has a shape in which the protruding portion 13 is formed at the tip, the convex shape can be easily bent, and the fitting force can be adjusted according to the specification.

（実施の形態４）
本実施の形態４では、前述した実施の形態１と、電池カバー２および周壁１０の形状が異なる場合について述べる。その他の詳細な構成については、前述した実施の形態１と同様である。 (Embodiment 4)
In the fourth embodiment, a case where the shapes of the battery cover 2 and the peripheral wall 10 are different from those of the first embodiment will be described. Other detailed configurations are the same as those in the first embodiment.

図９は、本発明の実施の形態４に係る凹部と凸部との嵌合構造を示す拡大断面図である。すなわち、電池カバー２をケース部材３に装着した状態における、周壁１０周辺の拡大断面図である。   FIG. 9 is an enlarged cross-sectional view showing a fitting structure between a concave portion and a convex portion according to Embodiment 4 of the present invention. That is, it is an enlarged cross-sectional view around the peripheral wall 10 in a state where the battery cover 2 is attached to the case member 3.

図９に示すとおり、本実施の形態４では、電池カバー２の主たる構造がカバー天面４のみであり、カバー側面５を備えていない。また、周壁１０の形状が、前述した実施の形態１ないし３とは異なり、電池カバー２に覆われるような形状ではなく、周壁１０の表面に電池カバー２を嵌め込むような形状となっている。   As shown in FIG. 9, in the fourth embodiment, the main structure of the battery cover 2 is only the cover top surface 4, and no cover side surface 5 is provided. Further, unlike the first to third embodiments described above, the shape of the peripheral wall 10 is not a shape that is covered by the battery cover 2 but a shape that fits the battery cover 2 on the surface of the peripheral wall 10. .

電池カバー２の凸部７の形状は、実施の形態２と同様であり、端部に向かって幅が漸減するテーパ構造となっている。その他の構成要素については、実施の形態１と同様であり、凸部７の少なくとも一部において凹部１１の相対向する外側の内面（図９に示すＹ）に接触し、軽圧入となって嵌合している。すなわち、カバー側面５ではなくカバー天面４の周縁部に力が働き隙間が少なくなるという点では異なるが、実施の形態１において述べた電池固定構造に働く力とほぼ同様の力が働く。   The shape of the convex portion 7 of the battery cover 2 is the same as that of the second embodiment, and has a tapered structure in which the width gradually decreases toward the end portion. The other components are the same as those in the first embodiment, and contact at least a part of the convex portion 7 with the opposite inner surface (Y shown in FIG. 9) of the concave portion 11 and light press fit. Match. That is, although the force is applied not to the cover side surface 5 but to the peripheral edge portion of the cover top surface 4 and the gap is reduced, substantially the same force as the force applied to the battery fixing structure described in the first embodiment is applied.

このように、本実施の形態４の電池固定構造によれば、充分に電池カバー２のガタツキおよびキシミの発生を抑制させ、かつ、電池カバー２における爪部６の係合力を高めることが可能となる。また、構造が複雑になりすぎず、製造コストが高くなることはない。さらに、凸部７の端部がテーパ構造となっているので、ケース部材３の凹部１１と嵌合させるための組み込みが容易となる。   As described above, according to the battery fixing structure of the fourth embodiment, it is possible to sufficiently suppress the backlash and creaking of the battery cover 2 and to increase the engaging force of the claw portion 6 in the battery cover 2. Become. Further, the structure is not excessively complicated and the manufacturing cost is not increased. Furthermore, since the end portion of the convex portion 7 has a tapered structure, it is easy to incorporate it into the concave portion 11 of the case member 3.

実施の形態１ないし４において述べた、凸部７、凹部１１（および周壁１０）、爪部６ならびに爪係止部９の位置および形状は一例である。凸部７および凹部１１が軽圧入となって嵌合、スライドが可能であり、爪部６および爪係止部９についても係合可能であれば、どのような位置および形状でも構わない。   The positions and shapes of the convex portion 7, the concave portion 11 (and the peripheral wall 10), the claw portion 6 and the claw locking portion 9 described in the first to fourth embodiments are examples. As long as the convex part 7 and the concave part 11 are lightly press-fitted and can be fitted and slid, and the claw part 6 and the claw locking part 9 can also be engaged, any position and shape may be used.

さらに、本発明は凸部７および凹部１１の長さについては限定されない。前述したように、凸形状の部分を凹形状の部分に嵌合させ、スライドさせる方法については公知であるため、当該分野の当業者であれば様々な設計が可能である。また、周壁１０についても、少なくとも相対向する部分が形成されていればよく、例えばケース部材２の周縁を囲むようなコの字状に形成されていても構わない。   Furthermore, the present invention is not limited to the lengths of the convex portion 7 and the concave portion 11. As described above, since a method of fitting and sliding the convex portion to the concave portion is known, various designs are possible for those skilled in the art. Also, the peripheral wall 10 may be formed in a U-shape that surrounds the periphery of the case member 2 as long as at least the opposing portions are formed.

また、実施の形態１ないし４においては、携帯電話機１の電池固定構造において本発明である搭載物固定構造を用いる例について説明したが、ケース部材とカバー部材とから構成され、任意の搭載物を収納するための固定構造に適用することが可能である。   In the first to fourth embodiments, the example in which the mounted object fixing structure according to the present invention is used in the battery fixing structure of the mobile phone 1 has been described. However, an arbitrary mounted object is configured by a case member and a cover member. It can be applied to a fixing structure for storing.

以上、実施の形態について説明したが、本発明は上述した実施の形態に限定されることはなく、本発明の範囲内で種々の実施形態が可能である。   Although the embodiments have been described above, the present invention is not limited to the above-described embodiments, and various embodiments are possible within the scope of the present invention.
