Claims

[Scope of utility model registration request]

A drive gear installed on a rotating shaft rotated by the engine, a sleeve inserted and fixed into a mounting hole provided at the top of a case housing the rotating shaft, and rotating inside an inner hole extending in the vertical direction of the sleeve. A rotating shaft that can pass through the sleeve and be secured by a clip to the sleeve, and one end of the speedometer cable is connected to the upper end of the shaft so as to be able to transmit torque, and a rotating shaft that is provided at the lower end of the rotating shaft and connected to the drive gear In a speedometer drive mechanism comprising driven gears that mesh with each other, a protrusion that protrudes laterally on the inner wall of the case and faces downwardly of the driven gear is provided, and a distance between the upper surface of the protrusion and the lower surface of the driven gear is provided. A structure for preventing a driven gear from falling off in a speedometer drive mechanism, characterized in that the driven gear is set to approximately half or less of the vertical length of the teeth of the driven gear.
