HOLDING STRUCTURE OF STORAGE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive holding structure which can prevent erroneous incorporation by elastically engaging it with a timepiece movement constitutive member by an engaging part integrally constituted in an electrically continuing part having a bayonet structure which can be elastically deformed in the radial direction of a storage battery of a lead plate welded to one pole of the storage battery and is pressed to and engaged with a side through pattern of the storage battery. SOLUTION: A conductive pattern 3a connectable to a storage battery lead plate 2 is formed on a side surface of an engaging recessed part arranged on a side surface of a battery housing part formed in a circuit block 3. The storage battery lead plate 2 is welded to a storage battery 1 by a welding part 2b. A tip part 2a of the storage battery lead plate 2 has springiness such as opening in the radial direction of the storage battery 1 by projecting outside from an outer peripheral part of the storage battery 1, and electrically continues with the conductive pattern 3a of the circuit block 3, and prevents upward slipping- out of the storage battery 1. The minus pole side is electrically continued with the circuit block 3 by a battery receiving spring 4 arranged under the storage battery 1.
