Title:
DIFFERENTIAL GEAR DEVICE
Document Type and Number:
Japanese Patent JP2019173830
Kind Code:
A
Abstract:
To provide a differential gear device in which a ring gear is fastened and fixed to a differential case with a plurality of bolts, and which can efficiently prevent the loosening of the bolts.SOLUTION: A differential gear device comprises an outer tooth type ring gear and a differential case which integrally rotates together with the ring gear. An attachment part which is integrally formed into a flange shape is formed at a periphery along a shaft rotation direction of a rotating shaft of the ring gear in the differential case, the ring gear is fastened and fixed to the attachment part with a plurality of bolts, and the plurality of bolts are aligned in the shaft rotation direction of the rotating shaft, and arranged so that the arrangement density of the bolts becomes low in a portion in which a stiffness change of the differential case is small, and becomes high in a portion in which the stiffness change is large.SELECTED DRAWING: Figure 2
