The present invention provides a method of manufacturing a sufficiently strong, box-shaped protective cover for a vibrating compactor inexpensively using a small number of processes and only simple processes, and provides a protective cover for a vibrating compactor.;A box-shaped protective cover that covers an upper structural portion of a body of a vibrating compactor is manufactured by executing a cutting process for fashioning a single metal plate into a shape including a first planar portion 1, a second planar portion 2, an intermediate portion 3, and a plurality of side flaps 5 (5a to 5d), a bending process for bending or curving the side flaps 5 and the intermediate portion 3, and a welding process for welding a side flap 5a (or 5b) of the first planar portion 1 to a side flap 5c (or 5d) of the second planar portion 2. |

1. A vibrating compactor protective cover manufacturing method for manufacturing a box-shaped protective cover that covers an upper structural portion of a body of a vibrating compactor by executing a cutting process for fashioning a single metal plate into a shape including a first planar portion, a second planar portion, an intermediate portion, and a plurality of side flaps, a bending process for bending or curving the side flaps and the intermediate portion, and a welding process for welding a side flap of the first planar portion to a side flap of the second planar portion, wherein
in the cutting process, the single metal plate is fashioned so that the intermediate portion is disposed between the first planar portion and the second planar portion, whereby the first planar portion, the intermediate portion, and the second planar portion are arranged in a single direction, the side flaps respectively project sideward from the first planar portion and the second planar portion, and a joint end edge formed in a position close to the intermediate portion on the side flap of the first planar portion opposes a joint end edge formed in a position close to the intermediate portion on the side flap of the second planar portion via a predetermined gap; in the bending process, first, the side flaps are bent or curved to one side, whereupon either the intermediate portion is curved about a virtual axis line that is orthogonal to an arrangement direction of the first planar portion, the intermediate portion, and the second planar portion or the first planar portion, the intermediate portion, and/or the second planar portion are bent along a bend line that is orthogonal to the arrangement direction of the first planar portion, the intermediate portion, and the second planar portion such that the joint end edge of the side flap of the first planar portion abuts the joint end edge of the side flap of the second planar portion; and in the welding process, the abutting joint end edges of the respective side flaps of the first planar portion and the second planar portion are welded. |
