Vehicle body manufacturing apparatus

A vehicle body manufacturing apparatus temporary to assemble a vehicle body by welding a first work of the vehicle body to a second work by spot the vehicle body manufacturing apparatus comprising:

• a jig to hold the first work of the vehicle body and to position, the first work to die second work, the first work being on the second work at a joint section;
• a welding gun to weld a weld portion in the joint section by at least one electrode that is moved along a pressure axis and pressed against the weld portion;
• and
• a welding position fixing member to fix a position of the pressure axis along which the at least one electrode of the welding gun is moved,
• wherein the jig and the welding position fixing member are configured to directly and simultaneously clamp the first and second works at the joint section between the jig and the welding position fixing member by tire welding position fixing member moving toward the jig in the coaxial direction of the pressure axis, and wherein the welding gun and the welding position fixing member are attached to an arm movable with respect to the vehicle body and operating independently of the jig.
