<p>PURPOSE:To hold a battery holder in a package without fail by providing an engaging part in a lever, which is provided in the battery holder, equipped with flexibility and providing an engaging part, which is engaged to this engaging part, in the package. CONSTITUTION:A lever 7, which is formed integrally with a battery holder 5 on one side of the battery holder 5, is equipped with the sufficient flexibility. An engaging part 8 is provided in a spot close to the tip part of the lever 7 so as to be protruded toward the upper direction of the battery holder 5, and equipped with a surface 81, which is almost perpendicular in the inserting/ detaching direction of the battery holder 5, namely, in the direction of an arrow A(B), and a surface 82 inclined from this surface 81 toward the inner end part of the lever 7. Further, an engaging part 9, which is formed as a rectangular hole on an upper surface cover 2 of a package 1, is provided in a position corresponding to the engaging part 8 of the lever 7 when the battery holder 5 is inserted to a battery housing part 4A. Thus, normally, the battery holder 5 is strongly fixed to the package 1 and when a battery is exchanged, the battery holder 5 easily is taken out.</p> |
