PURPOSE: To sufficiently compensate a plural number of wrong adjustment of one linear guide by making a second neutral axis of a bearing block roughly orthogonal with its first neutral axis. CONSTITUTION: A first bending web 28 has a slender cross-section seen on a cutting flat surface CI in parallel with a first disc type space, this cross-section has long and short cross-section axes I1, K1, and the long cross-section axis I1 makes a first neutral axis I1 of a bearing block 16. A second bending 34 of the bearing block 16 is limited by second slit bottom parts 30a, 32a extending materially orthogonal with first slit bottom parts 24a, 26a of second slits 30, 32. At this time, this second bending web 34 has a slender cross-section having a long or short cross-section axis 12 seen on at a cutting flat surface CII materially in parallel with a second disc type space, the long cross-section axis 12 makes a second neutral axis 12 of the bearing block 16, and this second neutral axis 12 crosses with the first neutral axis 11 roughly at right angles. |
