Abstract
An ignition operation mechanism for slide type lighters that is capable of preventing accidental ignition or ignition due to erroneous use or the like while maintaining good operability, wherein pivots 22a, 22a for an operating cap 20 are made substantially circular in cross section and so sized as to form a vertically movable clearance as they are locked to a support section in the lighter main body, the pivots 22a, 22a for the operating cap 20 are normally urged to be positioned in the upper region of the interior of a support section by the spring force of a return spring for a piezoelectric mechanism 4, the operating cap 20 is slid until a lever member 21 strikes the lighter main body 1 and no longer moves in the slide direction, from which state (a), the operating cap is pressed downward, whereby the pivots 22a, 22a move downward (b) within the support section, whereupon pressing levers 23, 23 reach the operation stroke that overcomes the piezoelectric mechanism 4, producing a discharge voltage to enable ignition.
