A vehicle steering column (10) comprises an axially extending input shaft
(12) for connecting to a vehicle steering wheel. The input shaft (12)
is rotatable about an axis (A) upon rotation of the steering wheel. The vehicle
steering column (10) also comprises a housing (16) at least partially
enclosing the input shaft (12). A bearing (92) is interposed between
the housing (16) and the input shaft (12) and supports the input
shaft (12) for rotation about the axis (A). The housing (16) has
at least one series of axially spaced, annular ribs (52) that at least partially
extend around the bearing (92). Axially adjacent annular ribs (52)
are separated by an annular groove (58). A gasket (100) is interposed
between the bearing (92) and the ribs (52). The gasket (100)
encircles the bearing (92). The ribs (52) resist axial movement of
the gasket (100).
