PROBLEM TO BE SOLVED: To realize a storage block of a rechargeable electronic clock which can provide a reliable and stable contact structure, as well as to incorporate the same storage block in all kinds of rechargeable electronic clock and to provide the storage block at a low price, by preparing a storage block welded with a simple shaped negative lead plate (a member corresponding to the above- mentioned conductive member). SOLUTION: A secondary battery block formed by welding a simple shaped negative lead plate 2 to a second battery 1 is prepared. Consequently it can be used for all kinds of rechargeable clock in common, and the cost is reduced for welding and assembling. Also, a stable contact structure can be realized without increasing movement thickness by providing a bending part 2b at the tip of the negative lead plate 2 and pressing a contact spring 7 against the side of this bending part 2b and connecting it. |
