Title:
ELECTRONIC KEY STRUCTURE
Document Type and Number:
Japanese Patent JP3545647
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electronic key structure capable of enhancing a design effect in a mechanical key housing state and capable of reducing key rotating operation force at mechanical key using time.
SOLUTION: A mechanical key 17 is housed in a mechanical key housing part 15 dislocated to one side in a key body, an overhang part 18a of a key head 18 is housed in an expansion part 16a of an opening part 16, a bridge piece 19 projected to form a holder connecting hole 20 in the key head 18 just projects to the rear end surface center of the key body to be bilaterally symmetrically constituted in an external appearance to avoid the occurrence of a sense of incompatibility. Since the key head 18 of the mechanical key 17 can enlarge the lever length from the key axis, key rotating operation force at mechanical key using time can be reduced.
