Component mounting structure of vehicle

1. A component mounting structure of a vehicle comprising:

a frame assembly having a recess which is recessed in a predetermined direction;

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.

2. The component mounting structure of the vehicle according to claim 1 ,

wherein the connection element is connected to the intermediate section such that the connection element is threadingly engageable with the intermediate section and is disengageable from the intermediate section.

3. The component mounting structure of the vehicle according to claim 1 ,

wherein the frame assembly includes two or more elongated sections and a coupling section for coupling outer peripheral portions of the elongated sections which are adjacent to each other, and

wherein the inner space of the recess is an inner space of the coupling section.

4. The component mounting structure of the vehicle according to claim 3 ,

wherein the coupling section is placed such that an axis of the coupling section extends in a direction perpendicular to a lengthwise direction of one of the elongated sections.

5. The component mounting structure of the vehicle according to claim 1 ,

wherein the recess is formed with a bolt hole, and

wherein a second adjacent component adjacent to the frame assembly is fastened to the frame assembly by use of a fastening member placed via the bolt hole.

6. The component mounting structure of the vehicle according to claim 1 ,

wherein the recess has a function other than a function for mounting the first adjacent component to the frame assembly.

7. The component mounting structure of the vehicle according to claim 1 ,

wherein the intermediate section is removably mounted to the frame assembly in such a manner that the intermediate section pressingly contacts the inner peripheral surface of the recess or is moved away from the inner peripheral surface of the recess.

8. The component mounting structure of the vehicle according to claim 7 ,

wherein the intermediate section includes a restricting section which contacts an end surface at the opening of the recess to restrict a displacement of the intermediate section in the predetermined direction.

9. The component mounting structure of the vehicle according to claim 1 ,

wherein the fastening element is retained between the support element and the threading element, and pressingly contacts the inner peripheral surface of the recess as a threading engagement between the threaded portion and the threading element progresses.
