A speedometer gear device in which a drive gear 12 made of synthetic resin is provided in a differential case 1 that houses a differential mechanism so as to rotate integrally with the differential case 1, and a pinion gear 5 is meshed with the drive gear 12 to obtain the rotational speed. Then, the inner peripheral surface 12a of the tooth part of the drive gear 12 is fitted into the differential case 1, and a notch 4 cut in the radial direction is formed in the engagement portion of the drive gear 12 of the differential case 1, and the drive gear 12 is fitted with a notch 4 cut in the radial direction. An engaging protrusion 13 is formed on a vertical portion 12b extending from the inner circumferential surface 12a of the tooth portion of the gear 12,
In the drive gear coupling structure in which the engagement protrusion 13 is engaged with the notch 4 of the differential case 1, the tooth inner peripheral surface 12a of the drive gear 12 and the engagement protrusion 13 are connected to each other.
A coupling structure for a drive gear in a speedometer gear device, characterized by having a groove-like gap between the drive gear and the speedometer gear.
