。The intake box 40 includes two half-rests 42 and 44 made of synthetic resin. One half 42 is formed with an intake port 46 projecting to the side of the carburetor 32 and an opening 47 facing the intake passage of each carburetor 32, and the intake port 46 has a mesh as shown in FIG. A foreign matter inhalation prevention net 48 having small holes of the shape is integrally molded. The other half 44 is formed into a substantially bowl shape and has four cylindrical supports 50 (50a, 50b, 50C, only three of which are shown in the figure). The outer edges of the tips of these struts 50 are truncated conical surfaces (-1) The one half 42 is formed with a recess 52 into which this conical surface engages. are overlapped so that their tips fit into the recesses 52, and the peripheral edges of the two halves 42 and 44 are airtightly joined.That is, the joining surface of one half 42 is provided with an annular groove 54 as shown in FIG. On the other hand, an annular protrusion 56 is formed on the other half 44, and after fitting these annular grooves 54 and annular protrusion 56, both halves 42 are formed.
The outer circumferential edge of ゜44 is tightened with a tightening ring 58 having an opening-shaped cross section.
