<P>PROBLEM TO BE SOLVED: To elongate an effective length of an antenna by decreasing the number of components and the length of the antenna when reduced. <P>SOLUTION: An antenna includes at least: a first element; and a second element stored inside the first element. A flange part formed to have a large diameter is disposed at a lower end of the second element. A spring member that slides along an inner surface of the first element is attached to a lower part of the second element so as to contact with the flange part. A large diameter part of the spring member energizes outward an inner surface of the first element in a state that the second element is attached to the inside of the first element. A hook part having a protrusion that protrudes radially inward is disposed at a lower part of the spring member so as to protrude from a lower end part thereof. The spring member is fixed to the second element by engagement of the protrusion with a lower end part of the second element. <P>COPYRIGHT: (C)2013,JPO&INPIT |
