また、図２に示すように、この第１の筐体２の基端部２ａ側には、基地局と無線通信を行うためのロッドアンテナ（アンテナ）１５が設けられており、第１の筐体２に対して伸縮可能となっている。ロッドアンテナ１５は、第１の筐体２内部に収納可能な細い棒状のアンテナ本体１７と、この先端にアンテナ本体１７よりも太く形成されたトップ部１９とから構成されている。トップ部１９は、図３に示すように、アンテナエレメントとしてのコイル（アンテナ素子）２１と、コイル２１を覆い隠す有底略筒状のキャップ２３とから構成されている。   Further, as shown in FIG. 2, a rod antenna (antenna) 15 for performing wireless communication with the base station is provided on the base end 2a side of the first casing 2, and the first casing 2 is provided. The body 2 can be expanded and contracted. The rod antenna 15 includes a thin rod-shaped antenna main body 17 that can be accommodated in the first housing 2 and a top portion 19 that is formed thicker than the antenna main body 17 at the tip. As shown in FIG. 3, the top portion 19 includes a coil (antenna element) 21 serving as an antenna element and a bottomed substantially cylindrical cap 23 that covers the coil 21.

キャップ２３の外周面２３ａは、アンテナ本体１７の先端部側に位置するキャップ２３の開口部２３ｂから、キャップ２３の底面部２３ｃに向けて徐々に拡径する逆円錐状に形成されている。キャップ２３の開口部２３ｂには、アンテナ本体１７の先端に形成された雄ねじ部（ねじ止め部）２５に螺合する雌ねじ部２７が形成されている。このキャップ２３の雌ねじ部２７をアンテナ本体１７の雄ねじ部２５に螺合させた状態においては、雄ねじ部２５によってキャップ２３の開口部２３ｂが閉塞されると共に、キャップ２３内の空間にコイル２１が配されることになる。なお、このキャップ２３は、樹脂により形成されており、アンテナ本体１７に取り付けられる前に予め射出成形により製造される。
コイル２１は、前述した雄ねじ部２５からさらにアンテナ本体１７の先端側に一体的に形成された棒状のボビン２９に巻回されており、キャップ２３内の所定位置に固定されるようになっている。 The outer peripheral surface 23 a of the cap 23 is formed in an inverted conical shape that gradually increases in diameter from the opening 23 b of the cap 23 located on the distal end side of the antenna body 17 toward the bottom surface 23 c of the cap 23. In the opening 23 b of the cap 23, a female screw portion 27 that is screwed into a male screw portion (screw fixing portion) 25 formed at the tip of the antenna body 17 is formed. In a state where the female screw portion 27 of the cap 23 is screwed into the male screw portion 25 of the antenna body 17, the opening portion 23 b of the cap 23 is closed by the male screw portion 25, and the coil 21 is arranged in the space inside the cap 23. Will be. The cap 23 is made of resin, and is manufactured in advance by injection molding before being attached to the antenna body 17.
The coil 21 is wound around a rod-shaped bobbin 29 integrally formed on the distal end side of the antenna body 17 from the male screw portion 25 described above, and is fixed to a predetermined position in the cap 23. .

第１の筐体２の基端部２ａには、アンテナ本体１７を第１の筐体２に収納した状態において、前述したトップ部１９の一部を収納するためのアンテナ収納部（筒状収納部）３１が設けられている。アンテナ収納部３１は、円筒状に形成されており、第１の筐体２の基端部２ａ側に開口している。なお、このアンテナ収納部３１の内径は、前述したキャップ２３の開口部２３ｂ近傍の外径よりも大きく形成され、また、キャップ２３の底面部２３ｃ近傍の内径よりも小さく形成されている。   The base end portion 2a of the first housing 2 has an antenna housing portion (tubular housing) for housing a part of the top portion 19 in a state where the antenna body 17 is housed in the first housing 2. Part) 31 is provided. The antenna housing part 31 is formed in a cylindrical shape and opens to the base end part 2 a side of the first housing 2. The inner diameter of the antenna housing 31 is formed larger than the outer diameter of the cap 23 near the opening 23b, and smaller than the inner diameter of the cap 23 near the bottom 23c.

さらに、アンテナ収納部３１の内周面３１ａには、トップ部１９の基端部１９ａを当接させるストッパ３３が突出して形成されている。このストッパ３３には、アンテナ本体１７を挿通させる開口部３３ａが形成されている。なお、ストッパ３３の開口部３３ａの内径は、トップ部１９の基端部１９ａの外径よりも小さく、トップ部１９がストッパ３３の開口部３３ａを通過できないようになっている。
ストッパ３３の形成位置からアンテナ収納部３１の開口部３１ｂまでの長さは、アンテナ本体１７の雄ねじ部２５やキャップ２３の雌ねじ部２７の長さよりも長く、かつ、キャップ２３の長さよりも短くなっている。 Further, a stopper 33 that abuts the proximal end portion 19 a of the top portion 19 is formed on the inner peripheral surface 31 a of the antenna housing portion 31 so as to protrude. The stopper 33 has an opening 33a through which the antenna body 17 is inserted. The inner diameter of the opening 33 a of the stopper 33 is smaller than the outer diameter of the base end portion 19 a of the top portion 19, so that the top portion 19 cannot pass through the opening 33 a of the stopper 33.
The length from the position where the stopper 33 is formed to the opening 31b of the antenna housing 31 is longer than the length of the male threaded portion 25 of the antenna body 17 and the female threaded portion 27 of the cap 23, and shorter than the length of the cap 23. ing.

以上のように構成された携帯電話機１を携行する場合には、ロッドアンテナ１５を縮める、すなわち、アンテナ本体１７を第１の筐体２内部に収納すると共にトップ部１９をアンテナ収納部３１内に挿入すればよい。この際、キャップ２３は前述のように逆台形状に形成されているため、アンテナ収納部３１の開口部３１ｂからトップ部１９を挿入した際には、キャップ２３の中途部がアンテナ収納部３１の開口部３１ｂに嵌め合わされることになる。すなわち、キャップ２３とアンテナ収納部３１とが一体的に固定されることになる。   When carrying the cellular phone 1 configured as described above, the rod antenna 15 is contracted, that is, the antenna body 17 is housed in the first housing 2 and the top portion 19 is placed in the antenna housing portion 31. Insert it. At this time, since the cap 23 is formed in an inverted trapezoidal shape as described above, when the top portion 19 is inserted from the opening 31 b of the antenna housing portion 31, the middle portion of the cap 23 is the antenna housing portion 31. It will be fitted into the opening 31b. That is, the cap 23 and the antenna storage part 31 are fixed integrally.

また、トップ部１９をアンテナ収納部３１に挿入した際には、トップ部１９の基端部１９ａがアンテナ収納部３１のストッパ３３に当接する。ここで、アンテナ収納部３１の開口部３１ｂからストッパ３３までの長さは、雌ねじ部２７の長さよりも長いため、前述の当接状態において、キャップ２３の雌ねじ部２７を確実にアンテナ収納部３１内に収納することができる。
さらに、アンテナ収納部３１の開口部３１ｂからストッパ３３までの長さは、キャップ２３の長さよりも短いため、同当接状態においては、トップ部１９の先端部がアンテナ収納部３１から突出した位置に配されることになる。すなわち、通話や通信を行う際には、アンテナ収納部３１から突出したトップ部１９を把持してアンテナ本体１７を第１の筐体２の内部から引き出すようにロッドアンテナ１５を第１の筐体２から延ばせばよい。 Further, when the top portion 19 is inserted into the antenna housing portion 31, the base end portion 19 a of the top portion 19 abuts against the stopper 33 of the antenna housing portion 31. Here, since the length from the opening 31b of the antenna housing portion 31 to the stopper 33 is longer than the length of the female screw portion 27, the female screw portion 27 of the cap 23 is securely attached to the antenna housing portion 31 in the above-described contact state. Can be stored inside.
Further, since the length from the opening 31b of the antenna housing 31 to the stopper 33 is shorter than the length of the cap 23, the position where the tip of the top portion 19 protrudes from the antenna housing 31 in the contact state. Will be placed. That is, when performing a call or communication, the rod antenna 15 is moved to the first housing so as to hold the top portion 19 protruding from the antenna housing portion 31 and pull out the antenna body 17 from the inside of the first housing 2. Just extend from 2.

上記のように、この携帯電話機１によれば、有底筒状のキャップ２３内の空間にコイル２１を配することにより、コイル２１の変形を確実に防止することができ、コイル２１のアンテナ性能を十分に発揮することが可能である。
また、携帯電話機１を携行する際に、アンテナ本体１７を第１の筐体２内部に収納すると共にキャップ２３の雌ねじ部２７をアンテナ収納部３１に収納しておくことにより、雌ねじ部２７がアンテナ収納部３１により保護されることになる。このため、落下等の衝撃が発生しても、キャップ２３の壁部のうち、雌ねじ部２７を構成する部分とコイル２１の収容空間を構成する部分との間に応力が発生することを防止して、キャップ２３の保護を図ることができる。したがって、強度的に優位なロッドアンテナ１５を備えた携帯電話機１を提供することができる。 As described above, according to the mobile phone 1, by arranging the coil 21 in the space in the bottomed cylindrical cap 23, the deformation of the coil 21 can be surely prevented, and the antenna performance of the coil 21 can be prevented. Can be fully demonstrated.
Further, when the mobile phone 1 is carried, the antenna main body 17 is housed in the first housing 2 and the female screw portion 27 of the cap 23 is housed in the antenna housing portion 31, so that the female screw portion 27 can be connected to the antenna. It is protected by the storage unit 31. For this reason, even if an impact such as a drop occurs, stress is prevented from occurring between the portion constituting the female screw portion 27 and the portion constituting the accommodating space of the coil 21 in the wall portion of the cap 23. Thus, the cap 23 can be protected. Therefore, the mobile phone 1 including the rod antenna 15 that is superior in strength can be provided.

さらに、逆台形状に形成されたキャップ２３を略円筒状のアンテナ収納部３１の内周面３１ａに嵌め合わせることにより、アンテナ本体１７を第１の筐体２内部に収納して携帯電話機１を携行している際に、トップ部１９が不意にアンテナ収納部３１から飛び出ることを確実に防止できる。
また、キャップ２３をアンテナ収納部３１に嵌め合わせることで、トップ部１９をアンテナ収納部３１に一体的に固定することができるため、落下等の衝撃に基づいてキャップ２３がアンテナ収納部３１に衝突して前述と同様の応力が発生することも防止できる。 Further, the cap 23 formed in an inverted trapezoidal shape is fitted to the inner peripheral surface 31a of the substantially cylindrical antenna storage portion 31, whereby the antenna body 17 is stored in the first casing 2 and the mobile phone 1 is connected. When carrying, it can prevent reliably that the top part 19 jumps out of the antenna accommodating part 31 unexpectedly.
In addition, the top portion 19 can be integrally fixed to the antenna housing portion 31 by fitting the cap 23 to the antenna housing portion 31, so that the cap 23 collides with the antenna housing portion 31 based on an impact such as dropping. Thus, it is possible to prevent the same stress as described above from occurring.

さらに、トップ部１９がアンテナ収納部３１のストッパ３３に当接した状態においては、雌ねじ部２７がアンテナ収納部３１内に収納されることになるため、雌ねじ部２７がアンテナ収納部３１により保護されていることを容易に把握することができる。
また、トップ部１９がストッパ３３に当接した状態においては、トップ部１９の先端部がアンテナ収納部３１から突出した位置に配されるため、ロッドアンテナ１５を第１の筐体２から容易に引き出すことができる。
さらに、キャップ２３は、アンテナ本体１７に取り付けられる前に予め射出成形により製造されるため、従来のように、コイル２１をインサート成形により樹脂封止する場合と比較して、安価に携帯無線機を製造することができる。 Further, in a state where the top portion 19 is in contact with the stopper 33 of the antenna storage portion 31, the female screw portion 27 is stored in the antenna storage portion 31, so that the female screw portion 27 is protected by the antenna storage portion 31. Can be easily grasped.
Further, when the top portion 19 is in contact with the stopper 33, the tip end portion of the top portion 19 is arranged at a position protruding from the antenna housing portion 31, so that the rod antenna 15 can be easily removed from the first housing 2. It can be pulled out.
Furthermore, since the cap 23 is manufactured by injection molding in advance before being attached to the antenna body 17, the portable wireless device can be manufactured at a lower cost compared to the case where the coil 21 is resin-sealed by insert molding as in the prior art. Can be manufactured.

なお、上記の実施形態においては、キャップ２３が逆台形状に形成されるとしたが、これに限ることはなく、少なくともキャップ２３がアンテナ収納部３１の内周面３１ａに嵌め合わせ可能に形成されていればよい。すなわち、例えば、キャップ２３の外周面２３ａ及びアンテナ収納部３１の内周面３１ａが相互に係合するように、これら外周面２３ａや内周面３１ａに突起や突起に係合する凹部を形成するとしても構わない。
また、キャップ２３の開口部２３ｂには雌ねじ部２７が形成されるとしたが、これに限ることはなく、例えば、アンテナ本体１７の先端部に雌ねじ部（ねじ止め部）を形成し、キャップ２３の開口部２３ｂにこの雌ねじ部に螺合する雄ねじ部が形成されるとしても構わない。 In the above embodiment, the cap 23 is formed in an inverted trapezoidal shape. However, the present invention is not limited to this, and at least the cap 23 is formed so as to be fitted to the inner peripheral surface 31a of the antenna housing portion 31. It only has to be. That is, for example, the outer peripheral surface 23a and the inner peripheral surface 31a are formed with protrusions and recesses that engage with the protrusions so that the outer peripheral surface 23a of the cap 23 and the inner peripheral surface 31a of the antenna housing 31 are engaged with each other. It does not matter.
In addition, although the female screw portion 27 is formed in the opening 23b of the cap 23, the present invention is not limited to this.
