Japanese Patent JP2020153493
Kind Code:
A
Abstract:
To eliminate the necessity for securing a wide side gear assembling space between a differential case inner face and a pinion gear even though an annular recess and a protrusion are specially formed for the prevention of the displacement of a side gear, in a differential device which can be engaged so that the annular recess is formed at one of mutually opposing faces between a differential case inner face and a side gear back face, the protrusion is formed at the other, and the annular recess and the protrusion permit the rotation of the side gear when the side gear is in a normal attachment position in the differential case, but prohibit a revolution around a pinion shaft.SOLUTION: In a differential device 10, one of opposing faces having an annular recess 50 out of mutually opposing faces of an inner face 8i of a differential case 8 and a side gear back face 23f has a passage groove 51 which communicates with the annular recess 50, and has a shape allowing a protrusion 61 to pass therethrough, and a groove width of an opening part e facing the annular recess 50, of the passage groove 51 is narrower than an outside diameter of the annular recess 50.SELECTED DRAWING: Figure 4
