Description

[Detailed explanation of the idea] This invention relates to a cover device for an outboard motor.

As schematically shown in FIG. 1, the outboard motor is equipped with an engine 2 and a fuel tank 3 in the upper part of a casing 1, and transmits the rotation of the engine 2 to a propeller shaft 4 in the lower part of the casing 1.
Generally used is one that propels the hull by driving the upper propeller 5, but the engine room 6 in which the engine 2 and fuel tank 3 are mounted is covered with an engine cover 7 made of synthetic resin. It's becoming like that.

However, the engine cover 7 is opened and closed relatively frequently, such as during maintenance and inspection of the engine 2 and when filling fuel into the fuel tank 3. Fixing members such as rivets that fix this metal fitting may come into contact with the painted surface of the fuel tank 3 and cause the paint to peel off, or be easily scratched by the engaging metal fittings or fixing members. There was a problem in that the tank 3 caused rust and the service life of the fuel tank 3 was shortened.

Therefore, in the past, the engaging metal fittings and fixing members were treated with vinyl coating, etc., so that they would be less likely to be scratched even if they came into contact with the fuel tank 3, but even then, sufficient effects could not be obtained. Ta.

This invention focused on the above-mentioned conventional problems and was made with the aim of improving them.The engaging fitting and its fixing device are attached to the side of the part where the engaging fitting is attached to the synthetic resin engine cover. A rib is integrally provided that protrudes from the other parts, so that even if the inner surface of the engine cover comes into contact with the fuel tank, the outer edge of the rib will come into contact with the fuel tank to prevent the engaging metal fittings from coming into contact with the fuel tank. A cover device for an outboard motor is provided.

Embodiments of this invention will be described below with reference to FIGS. 2 and 3, in which the same reference numerals are given to parts common to those in FIG. 1.

Fig. 2 shows a vertical cross section of the main part of the engine cover 7 according to this invention, and Fig. 3 shows a horizontal cross section of the same, in which ribs 8, 8 are provided in the vertical direction at the bottom of the inner surface of the engine cover 7 made of synthetic resin. The engine cover 7 is provided integrally with the engine cover 7 at intervals, and an engaging metal fitting 9 is fixed between the ribs 8, 8 by rivets 10, 10.
The heads 10a, 10a of the ribs 8, 10 are recessed deeper than the outer edges of the ribs 8, 8.

Therefore, even if the inner surface of the engine cover 7 hits the outer surface of the fuel tank 3 when the engine cover 7 is attached or detached, the heads 10a, 10a of the engaging fittings 9 and rivets 10, 10 will not be pulled in between the ribs 8, 8. Since these are located at the same angle, they do not come into contact with the fuel tank 3, and only the ribs 8, 8 come into contact with the fuel tank 3. Furthermore, these ribs 8, 8 are integrally molded with the engine cover 7, and are made of synthetic resin, so they are soft. Thus, unlike hard metal engagement fittings and their fixing members, even if they come into contact with the wall surface of the fuel tank 3, it is possible to effectively prevent the tank wall surface from being scratched or damaged. Therefore, there is no possibility that the paint on the fuel tank 3 will be peeled off or scratched.

As described above, this invention is based on the location where the engagement fittings of the engine cover are attached in an outboard motor that has an engine room in the upper part of the casing and covers the engine, fuel tank, etc. with a synthetic resin engine cover. A rib that protrudes beyond the engaging fitting and its fixing member is integrally provided on the side of the engine cover, so even if the cover comes into contact with the fuel tank when the engine cover is attached or removed, the engaging fitting or its fixing member will not be damaged. Since there is no contact with the surface of the fuel tank and the ribs do, there is no need to peel off or damage the paint on the fuel tank, and there is no need to coat the related metal fittings, reducing costs. In addition, the engine cover is reinforced with ribs, and even if the cover is made of synthetic resin, it has various effects such as increasing its strength and durability.
