Abstract
The linear motion rolling guide unit makes efficient use of the spaces in the casing to easily attach the under seals to the end caps in such a way that deformation by thermal expansion and swelling can be dealt with, assuring a good sealing performance. The under seals are provided with a longitudinally extending core band, which has hook portions at its ends. The outer end surfaces of the end caps are formed with engagement holes, into which the hook portions are fitted. If there are differences in thermal expansion between the end caps and the under seals, or if deformations occur due to swelling, the hook portions of the core band elastically deform absorbing the dimensional changes to prevent the under seals from being distorted or buckled.
