Abstract
A welded structure makes a relationship between one intermittent weld which fixes a long member to a base material and the other intermittent weld which fixes a plate-shaped member to the long member appropriately respond to a type of a load which dominantly acts on the long member. A lower long side edge of a beam member which serves as the long member is fixed onto a machine body frame which serves as the base material by intermittent welds. A top plate which serves as the plate-shaped member is fixed onto an upper long side edge of the beam member by the other intermittent welds. In a region where a load which twists the top plate dominantly acts on the beam member, a parallel weld portion in which the intermittent welds and the intermittent welds are welded in a parallel weld form is employed, and in a region where a bending load from the top plate dominantly acts on the beam member, the zigzag weld portion in which the intermittent weld and the intermittent weld are welded in a zigzag weld form is employed.
