a net frame in which the net structure is drawn;
a receiving frame formed integrally with the seat frame; and
a fastening mechanism that fastens the net frame to the receiving frame,
wherein the receiving frame has an L-shaped cross-section, and an opening opened toward the net frame, the opening being closed by the net frame,
wherein a first reinforcement member is formed on an inner surface of the receiving frame facing to the net frame, the first reinforcement member extending along a lengthwise direction of the receiving frame,
wherein the net frame includes a first flange to which the first reinforcement member is contacted, and
wherein the net frame is combined with the receiving frame such that the first flange is brought into contact to the first reinforcement member and fastened by the fastening mechanism.

2. The vehicle seat as claimed in claim 1 , further comprising:
a sheet member that covers the net structure; and
a clearance formed between a portion of the receiving frame and the net frame,
wherein an outer edge of the sheet member is inserted into the clearance.

a sheet member that covers the net structure; and
a second reinforcement member formed on an opposite surface of the receiving frame to the surface on which the first reinforcement member is formed,
wherein said second reinforcement member includes a fitting groove, and
an outer edge of the sheet member is inserted into the fitting groove.

5. The vehicle seat as claimed in claim 1 , wherein an edge of the first flange is brought into contact with the first reinforcement member.

6. The vehicle seat as claimed in claim 1 , wherein an entirety of an edge of the first flange is brought into contact with the first reinforcement member.

7. The vehicle seat as claimed in claim 1 , wherein
the net frame includes a second flange,
the receiving frame includes a first wall portion and a second wall portion,
the first reinforcement member is formed on each of the first wall portion and the second wall portion,
