A construction is provided for fastening a plurality of members which thermally expand and contract together to a base member with a screw member, in such a manner that those members do not interfere with each other when they thermally expand or contract. An interference that would otherwise be generated between a plurality of members to be fastened together when the respective members thermally expand and contract can be prevented with a simple construction by interposing an interference preventing spacer member between the respective members. The spacer member is positioned in a radial direction relative to a screw portion. With one member, the fastened portion where the members are fastened together functions as a reference point for absorbing the thermal expansion and contraction. With the other member, an elongate hole is used at this fastened portion for absorbing the thermal expansion and contraction. Accordingly, the single fastened portion allows fastening corresponding to the respective members. Moreover, since there is caused no looseness of the respective members, there is no risk of the aesthetic appearance of the members being damaged which are so fastened together to the base member.
