PURPOSE:To prevent a track member from deformation when a fixing member is secured fixedly to one side of the thin track member by bolts, by providing on the other side of the track member a nut having approximately same shape as a portion of the fixing member contacting the track member. CONSTITUTION:When a fixing member 7 is secure fixedly to a track member consisting of a table, bed, etc. made of steel sheet with bolts 9, nuts 8 having approximately same shape as a portion of the fixing member 7 contacting the track member are applied to the opposite side of the track member to the fixing member 7 to be secured fixedly by the bolts 9. As a result, deformation such as camber produced conventionally on the thin track member has been substantially reduced. |
