Abstract

A work machine that can discharge water collected inside a casing to the outside, reduce leakage of noise, and reduce entry of foreign matter from outside. The work machine includes a bottom portion cover forming a portion of a casing, and the bottom portion cover includes: at least two ribs and a bead (strengthening structure portions) that are formed substantially perpendicular to a bottom surface of the bottom portion cover; and a drain hole located in a connecting portion connecting the bottom surface of the bottom portion cover and a water-discharging rib among the at least two ribs. An upper portion of the water-discharging rib is located over the drain hole.

First claim

1 . A work machine comprising a bottom portion cover forming a portion of a casing,
the bottom portion cover comprising: at least two strengthening structure portions formed substantially perpendicular to a bottom surface of the bottom portion cover; and a drain hole located in a connecting portion connecting the bottom surface of the bottom portion cover and a strengthening structure portion among the at least two strengthening structure portions, the strengthening structure portion having an upper portion located over the drain hole, at a location at which the at least two strengthening structure portions are formed in a lattice shape, the at least two strengthening structure portions intersecting with each other substantially orthogonally in the lattice shape, the drain hole being formed at a position of intersection of the at least two strengthening structure portions, at a location at which the at least two strengthening structure portions are not formed in a lattice shape, the drain hole being formed in a substantially middle portion of the strengthening structure portion in a width direction of the strengthening structure portion, the bottom portion cover being located at a bottom portion of the casing of a generator to support an engine of the generator, the at least two strengthening structure portions being formed between engine-retaining structure portions for supporting the engine.

2 . The work machine according to claim 1 ,
wherein the at least two strengthening structure portions comprise: water-discharging structure portions each including the drain hole; and a blocked structure portion including no drain hole, and the blocked structure portion is located between the water-discharging structure portions.

3 . The work machine according to claim 1 ,
wherein each of the at least two strengthening structure portions is a bead or a rib for reinforcing the bottom portion cover.

4 - 6 . (canceled)

7 . The work machine according to claim 2 ,
wherein each of the at least two strengthening structure portions is a bead or a rib for reinforcing the bottom portion cover.
