Abstract
A flint-type ignition mechanism comprising a freely rotatable support member; a spark wheel combined with the supporting member so as to be integrally rotatable with same; an elastic member installed around the support member; a thumb wheel having a gear-type inner face installed around the elastic member so that it can idle, the thumb wheel switching between the concentric and eccentric position; and a disk-shaped engaging member which rotates together with the supporting member and has engagement stoppers on the peripheral surface of the exterior circumference thereof for engaging the gear type inner face of the thumb wheel. When the thumb wheel is switched to the eccentric position by a deformation of the elastic member, the stoppers engage together and the spark wheel rotates together with the thumb wheel, causing it to be in the ignite-state. In the ignite-state, rotation of the thumb wheel rotates the spark wheel for ignition.
