<p>PROBLEM TO BE SOLVED: To provide an automatic extendable antenna that extends at one-touch. SOLUTION: An approximate center to a lower part of an antenna 2a stored in a cellular phone main body 1 is made a large diameter part 3, and the upper part is made a small diameter part 4. A stepped part 5 is formed at a boundary of the large diameter part 3 and the small diameter part 4. A spring 8 that extends the antenna 2a is inserted and attached in the large diameter part 3. A lock member 18 integrally formed with a lock piece 14 and an elastic piece 15 is arranged opposed to the antenna 2a. A slide button 25 is arranged on the outside of the lock member 18. By sliding the slide button in one direction, the lock piece 14 is pressed to lock the stepped part 5 of the antenna. By sliding the slide button in the other direction and releasing the pressure, the lock is released by the elastic force of the elastic piece 15. Then, the antenna is automatically extends by the elastic force of the spring 8.</p> |
