• an intermediate section accommodated in the recess and removably fastened to the frame assembly;
• and
• a mounting member used to mount a first adjacent component adjacent to the frame assembly to the frame assembly,
• wherein the mounting member includes a connection element connected to the intermediate section in an inner space of the recess and a support element which is continuous with the connection element and supports the first adjacent component in a state in which the connection element is exposed outside through an opening of the recess,
• wherein the connection element has a threaded portion placed in the recess,
• wherein the intermediate section includes a fastening element which pressingly contacts an inner peripheral surface of the recess and a threading element threadingly engaged with the threaded portion, and
• wherein the fastening element and the threading element have surfaces facing each other that are spaced apart from each other in an axial direction of the threaded portion, and inclined surfaces which extend from the surfaces facing each other are located radially outward of the threaded portion, are inclined with respect to a radial direction of the threaded portion, and are in surface contact with each other.
