Description

[Detailed Description of the Invention] The present invention relates to a water draining device for a generator for a motorcycle or other two-wheeled vehicle.

Conventionally, this type of device is known to have a drainage hole at the bottom of the cover on the outer periphery of the generator that communicates with the inside. This is likely to be sucked in next time and damage the function of the generator.Thus, it has been proposed to form the drain hole into a curved labyrinth to prevent water from entering as much as possible; Formation is not necessarily easy and involves inconveniences such as requiring time and effort.

The purpose of the present invention is to obtain a device free from such inconveniences, and includes an engine 3 mounted on a vehicle body 2 having front and rear wheels 1, 1 to constitute a motorcycle or other two-wheeled vehicle. In a type that includes a generator 4 interlocked with the generator 4 on the side of the engine 3, and a case 5 around the outer periphery of the generator 4, the engine 3 is connected to the vehicle body 2 through the case 5.
Alternatively, the rib 7 to which the stand, step, or other member 6 is to be attached may be integrally protruded downward, and the drain hole 8 communicating the inside of the case 5 to the outside may be formed in a hollowed part in advance on the side surface of the rib 7. It is made to open in 9.

To explain in detail what is shown in the figure, the engine 3 is of a type having a crankshaft 3b inside a crankcase 3a, as shown in FIG. Furthermore, as shown in the figure, the generator 4 is installed on the crankshaft 3b and is provided with the case 5 on its outer periphery. It is made up of two parts: a cylindrical frame housing 5a that integrally extends laterally from the crankcase 3a, and a cover 5b attached thereto, and furthermore, the ribs 7 are integrally attached to the frame housing 5a side. It was made to be formed. The rib 7 has a bolt hole 10 at its lower end and a hollowed out part 9 above it, and the hollowed out part 9 is dug perpendicular to the running direction of the two-wheeled vehicle. Bolt 1 in bolt hole 10
A bracket 12 is fixed through the bracket 1, and a pedal or other member 6 can be attached to the bracket 12 through the bracket 12.

It should be noted that a cover member 13 is applied to the opening surface of the hollowed out portion 9 as shown in FIG. 4, if necessary.
The lid member 13 can be fixed freely using the lid member 1, and a small hole 14 is provided in the lid member 13.

To explain its operation, the drain hole 8 at the bottom of the case 5 opens into a hollowed out part 9 on the side surface of the rib 7, as shown in FIG. 2 or 3, for example. 8 cooperates with the section 9 to form a labyrinth as a whole, through which no water is sucked, and when the hollow section 9 is dug perpendicular to the running direction of the two-wheeled vehicle, for example, the third As clearly shown in the figure, there is no possibility of water splashing in in a direction lateral to the direction of water splashing (indicated by the arrow).

In this way, according to the present invention, the drain hole 8 is opened in the hollowed out part 9 on the side surface of the rib 7 extending downward, and the drain hole 8 cooperates with the hollowed out part 9 to form a labyrinth-like shape as a whole. Thus, it does not have the above-mentioned disadvantages of the conventional method in which the drainage hole 8 itself is formed into a curved labyrinth, and furthermore, the hollowed out portion 9 is provided in the rib 7 in advance for weight reduction and other purposes. It has the advantage that it is simple and easy to use.
