PROBLEM TO BE SOLVED: To provide a joint cover which can improve sealability with a partition plate.SOLUTION: A joint cover 21 connects an opening 17D of a pinion housing 17 accommodating a pinion shaft 4 to an insertion hole 14A formed in a partition plate 14 separating the inside and outside of a vehicle cabin 15. The joint cover 21 includes a base 22, an expansion and contraction layer 23, a seal layer 24, and a guide 30. The base 22 includes a cylindrical part 26 fitted into the opening 17D and a flange part 27 arranged so as to face a peripheral part 14C of the insertion hole 14A. The expansion and contraction layer 23 is compressed between the partition plate 14 and the flange part 27. The seal layer 24 is pressed against the peripheral part 14C by the expansion and contraction layer 23 to be brought into close contact with the peripheral part 14C. The guide 30 projects closer to the partition plate 14 side than the seal layer 24 and is inserted into the insertion hole 14A. |
