Fig. 2 is the first structural representation of the present utility model；
Fig. 3 is second of structural representation of the present utility model.
Embodiment
Preferred embodiment of the present utility model is elaborated below in conjunction with the accompanying drawings：
Referring to Fig. 2 and Fig. 3, the utility model automotive transmission oil sealing mounting structure, including case of transmission 1 are located at this
Axial seal mounting hole 10 on case of transmission 1, and including the approximate great circle cylinder 20 by interconnected coaxial line, small
The oil sealing that cylinder 21 and the inner ring 22 being connected within great circle cylinder 20 and small cylinder 21 are constituted and be made up of elastomeric material
2, the periphery of the great circle cylinder 20 of the oil sealing 2 is interference fitted with the axial seal mounting hole 10 on case of transmission 1, its inner ring
22 are set on axle.From Fig. 2 and Fig. 3, the utility model also includes at least one position limiting structure 101,201, described spacing
Structure 101,201 includes main position limiting structure 101 and coordinates position limiting structure 201, and the main position limiting structure 101 is located at case of transmission
