The present invention is not limited to the above-mentioned embodiments, and various design changes can be made without departing from the essence thereof. (Effects of the Invention) As described above, according to the first feature of the present invention, since the present invention is a windshield device for a two-wheeled locomotive, a front handle cover that is attached to the rod-shaped steering handle and covers the front face thereof is provided with the front handle cover facing the same. The air inlet opening at the front supplies the driving wind obtained from the air inlet to the inside of the windshield protruding upward from the front handle cover, wherein the upper half of the front slopes upward and the lower half of the front slopes downward. The front handle cover is formed by combining the parts in such a manner as to form a ridgeline in the left-right direction. The air inlet is provided in the lower half. Therefore, the air inlet of the front handle cover is provided in the front handle cover. The lower part of the front and the lower part below the ridge line, Keli 12 312 / Invention Manual (Supplement) / 92-11 / 92123420 593051 The effect of blocking the air inlet with a ridge line The front face faces the lower mouth ° In addition, based on the root, the front The edge touches or the air hole in the upper handle, the front plate will be from the above to enter the upper handle cover to the inside of the upper handle to produce the upper handle cover. The base, said jet holes integrally to the display surface groups. The inside of the windshield is formed from the diffusion of jet air. [The diagram is simple, and it is generally adult, so it can be. Moreover, since the side, according to the present invention, the handle cover and the air hole of the cover of the front handle cover of the front air inlet cover are provided with negative pressure in the front part of the cover of the steering handle close to the wind load according to the present invention. The invention of standing up between the upper handle cover to form the instrument guard, so that the air ejected from the air jet surface and the opposite hole can effectively explain] When people look at the front to prevent air from being guided by the front handle cover, the second, A feature is that an upper inner side is installed on the side, and a driving air obtaining port is provided facing between the wind handle covers to improve the wind-shielding effect from multiple sprays. A third feature is a cover is installed on the meter to prevent glare. In the rear direction of the eye hole group, the entrance of the line of sight which is in the windshield to suppress the rise of the air is provided to the second wheel. The opening of the second wheel is prevented from rain. The driving wind guided to the top, the stomata blow out, as a result. In addition, it is possible to obtain a good performance due to the recording assembly of the present invention, and the shroud is injected from the instrument line to the standing instrument to record the effect of the instrument shroud road. The inlet air is introduced above the handle of the handle cover on the first feature, and a plurality of spray plates at the mouth of the wind deflector are described by the air deflector and the appearance of the windshield can be controlled from the windshield. The second feature is that it is closer to the cover of the upper handle cover and the upper instrument element, and between the windshield and the windshield to prevent this spout from occurring. 312 / Invention Specification (Supplement) / 92-11 / 92123420 13 593051 Fig. 1 is a side view of a two-wheeled locomotive having a windshield device of the present invention.
