Document Type and Number:
Japanese Patent JP6706304
Kind Code:
B2
Abstract:
To discharge water or oil stagnated on a top face of a head cover to a position where the water or oil is prevented from being splashed over exhaust members.SOLUTION: In a head cover 11 comprising a liquid discharge passage 19 for discharging water or oil from a top face to a side face, a heat insulation plate 18 interposed between exhaust members 12 and 13 is fixed to the side face of the head cover 11, and a part of a passage sidewall of the liquid discharge passage 19 is constituted of the heat insulation plate 18, thereby preventing the water or oil from being splashed over the exhaust members 12 and 13. The head cover 11 comprises a projection 11s extending a downstream-side end portion of the passage sidewall 18a of the heat insulation plate 18 constituting a part of the passage sidewall to the side of a liquid discharge port 11q. Therefore, even in a case that the passage sidewall 18a does not reach the liquid discharge port 11q by lacking a length of the heat insulation plate 18, a liquid discharge passage 19 for a required length is obtained by extending the passage sidewall 18a with the projection 11s.SELECTED DRAWING: Figure 1
