BATTERY PACK LOCK MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a battery pack lock mechanism suitable for reducing manufacturing cost of a portable telephone set by simplifying metallic mold structures for parts constituting the battery pack lock mechanism. SOLUTION: A sliding knob 30 has a guide groove 31 and elastic pieces with inward hooks 32. A sliding recessed part 40 is provided with guide rails 41 and locking pieces 42. When the sliding knob 30 which preliminarily holds compressive springs 10 at the inside of left and right elastic pieces with inward hooks 32 is slid to the sliding recessed part 40 and tips of the elastic pieces 32 for inward hooks 32 and the locking pieces 42 are engaged by fitting of the guide rails 41 and the guide groove 31, the compressive springs 10 contract and the sliding knob 30 is locked within the sliding recessed part 40 in an energizing state by the reaction.
