Abstract: In a fuse box (10) mounted on a battery box (40), a lower end surface (12b) of a peripheral wall (12a) of an upper cover (12) is brought into contact with a bottom wall (13b) of a lower cover (13) that is locked to a case body (11) of the fuse box (10) or brought into contact with a bottom wall (11e) of the case body (11) to form a first watertight portion (A). A peripheral wall (11a) erect on the bottom wall (11e) of the case body (11) is formed by spacing the peripheral wall (11a) at a pressure-reducing gap (S) from an inner surface of the upper cover (12). A rib (11b) formed by outwardly bending an upper end of the peripheral wall (11a) of the case body (11) is projected toward an inner surface of the peripheral wall (12a) of the upper cover (12) to form a second watertight portion (B). The pressure-reducing gap (S) is interposed between the first watertight portion (A) and the second watertight portion (B).

Abstract: An electric junction box, disposed in a water penetration region, which accommodates bus bars inside a case body thereof and has fuses (fusible links connected with the bus bars. An upper cover and a lower cover are mounted on the case body with the case body, the upper cover, and the lower cover connected with one another. An entire peripheral wall of the upper cover is formed not as a double-wall construction, but an inner peripheral surface of the peripheral wall is brought into contact with an outer surface of an entire peripheral wall of the lower cover (or case body) to lock the peripheral wall and the entire peripheral wall of the lower cove to each other. In a watertight region including at least the fuses, a rib is projected in the shape of a frame from an inner surface of an upper wall of the upper cover so that the rib surrounds the watertight region.

Abstract: An electrical junction box for a motor vehicle comprises a casing, a pair of bus bars accommodated in and secured to the casing with the bus bars being exposed outward, and a fusible link having a link body, an input terminal and an output terminal that extend from the opposite sides of the link body. The input and output terminals are secured to the bus bars by bolts, respectively. The input and output terminals of the fusible are provided on the opposite side edges with ribs, respectively. Folding the bus bars forms U-bend portions to contact with outer side surfaces of the ribs. Alternatively, the U-bend portions may be provided on the inner surfaces of the casing.

Abstract: A chopper folding machine including a chopper blade and a conveyor belt driven synchronously by a drive system for a folding apparatus put in juxtaposition with a printing machine, and a timing adjusting device provided in a drive system for at least one of the chopper blade and the conveyor belt for adjusting the timing of chopper folding. Thus, the timing of the conveyance of a signature, to be folded, by the conveyor belt and that of vertical movement of the chopper blade are adjusted.
