The upper housing 200 and the lower housing 100 may be coupled to each other by fastening members such as fixing bolts. A gasket 350 for fluid sealing may be interposed between the lower housing 100 and the upper housing 200. The shell S may be formed by the lower shell half 110 and the upper shell half 210 inside each of the housings 100 and 200 when the lower housing 100 and the upper housing 200 are coupled to each other. The first lower cover half 120 forms a first cover C1 together with the first upper cover half 220 and the second lower cover half 130 forms a second The cover C2 can be formed.
