a fitting member provided at a second end of the at least one clamp jig; and
a fitting receiving member that is provided in the replaceable jig frame and guides the at least one clamp jig to a predetermined clamp position of the vehicle body by fitting to the fitting member, the fitting receiving member being shaped such that the fitting member can fixedly attach to the fitting receiving member.
2. The vehicle body manufacturing apparatus according to claim 1 , wherein the at least one clamp jig clamps the work in conjunction with fitting between the fitting member and the fitting receiving member.
3. The vehicle body manufacturing apparatus according to claim 1 , wherein the replaceable jig frame comprises an upper jig frame that is disposed in an upper portion of the jig frame structure.
4. The vehicle body manufacturing apparatus according to claim 2 , wherein the replaceable jig frame comprises an upper jig frame that is disposed in an upper portion of the jig frame structure.
5. The vehicle body manufacturing apparatus according to claim 1 , wherein the fitting receiving member is detachably provided in the replaceable jig frame.
6. The vehicle body manufacturing apparatus according to claim 2 , wherein the fitting receiving member is detachably provided in the replaceable jig frame.
7. The vehicle body manufacturing apparatus according to claim 3 , wherein the fitting receiving member is detachably provided in the replaceable jig frame.
8. The vehicle body manufacturing apparatus according to claim 4 , wherein the fitting receiving member is detachably provided in the replaceable jig frame.
9. The vehicle body manufacturing apparatus according to claim 1 , wherein the at least one clamp jig includes:
a clamp jig main body connected to the articulated arm at the first end; and
a clamp lever rockably pivotally supported by the clamp jig main body, the clamp lever having the fitting member provided thereon.
10. The vehicle body manufacturing apparatus according to claim 1 , wherein the fitting member is shaped as a protruding portion, and
wherein the fitting receiving member is shaped as a recessed portion.
11. The vehicle body manufacturing apparatus according to claim 1 , wherein the fitting member is provided on a portion of the at least one clamp jig that is rockably pivotally supported by the at least one clamp jig.
12. The vehicle body manufacturing apparatus according to claim 1 , wherein the articulated arm is fixedly attached to the at least one clamp jig at the first end, and
wherein the at least one clamp jig includes a portion that is pivotally supported by the at least one clamp jig and includes the fitting member at the second end.
13. The vehicle body manufacturing apparatus according to claim 1 , wherein the first end of the at least one clamp jig is further from the fitting receiving member than the second end of the at least one clamp jig.
14. The vehicle body manufacturing apparatus according to claim 1 , wherein the fitting member mates to the fitting receiving member.
15. The vehicle body manufacturing apparatus according to claim 1 , wherein the fitting receiving member is provided in the replaceable jig frame at a position such that the at least one clamp jig is guided to a predetermined clamp position of the vehicle body when the fitting member provided on the at least one clamp jig contacts the fitting receiving member.
16. The vehicle body manufacturing apparatus according to claim 1 , wherein the fitting receiving member is provided on the replaceable jig frame in a position facing the fitting member.
17. The vehicle body manufacturing apparatus according to claim 1 , wherein the fitting member is shaped as a V-shape protrusion, and
wherein the second fitting member is shaped as a V-shaped groove.
18. The vehicle body manufacturing apparatus according to claim 1 , wherein the at least one clamp jig includes a movable part having the fitting member disposed thereon.
19. The vehicle body manufacturing apparatus according to claim 1 , wherein the fitting member is shaped as a protruding portion, and
wherein the fitting receiving member is shaped as a recessed portion such that the protruding portion shape of the fitting member mates with the recessed portion.
