[Diagram 3] FIG. 4 is a plan view showing a display device according to a second embodiment of the present invention.

[Diagram 5] FIG. 11 is a cross-sectional view showing a display device according to a fourth embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] [First embodiment] FIG. 1 is a plan view showing a display device according to a first embodiment of the present invention. FIG. 2 is a cross-sectional view of the display device 1 taken along line AA in FIG. The display device 1 is disposed in the center of a handlebar 2 of the motorcycle, and displays information such as the vehicle speed. The display device 1 includes a touch panel 4, a display unit 5, a circuit board 6, a housing 7, a cover panel 8, and a handle cover 9.

[0013] Here, the display 5 is a liquid crystal panel that displays vehicle information, but an organic EL panel or the like may also be used. The touch panel 4 is disposed on the display 5. The touch panel 4 is a capacitive touch panel, and has electrodes 4A arranged in a grid pattern. The circuit board 6 is disposed on the rear surface of the display unit 5, and has a circuit for controlling the display of the display unit 5 and the like mounted thereon. The cover panel 8 is a light-transmitting transparent plate-like member that is disposed on the touch panel 4 to protect the touch panel 4. The housing 7 is a case that houses the display unit 5, the touch panel 4, the circuit board 6, and the cover panel 8, and is housed in an opening 9A formed in the handle cover 9 and held by the handle cover 9.

[0014] The handle cover 9 is installed inside the handle of the motorcycle. The handle cover 9 and the cover panel 8 are integrated together by two-color molding or by adhesion using double-sided tape or the like. This enables the display device 1 to prevent foreign matter from entering the housing 7.

[0015] The handle cover 9 located (extending) around the cover panel 8 is partially raised, and a convex drainage wall 9B is formed rising from the cover panel 8 side on the lower side of the display area of ​​the display device 5, outside the effective operation area of ​​the touch panel 4 related to the display screen of the display device 5. More specifically, the drainage wall 9B is formed in the vicinity of the horizontal electrode 4AX closest to the rider side, without covering the horizontal electrode 4AX located under the touch panel 4 closest to the rider side. Furthermore, the drainage wall 9B is formed in a curved shape such that the horizontal center of the display area of ​​the display 5 is convex toward the display 5 side. This allows the display device 1 to quickly remove water droplets that have adhered due to gravity without impairing the rider's operation of the touch panel, thereby reducing malfunctions caused by the adhesion of water droplets. In particular, in the case of motorcycles, when a rider turns, the rider will tilt the handlebars. This allows water droplets to flow to both sides of the drainage wall 9B when the rider tilts the handlebars, and further reduces malfunctions caused by water droplets adhering to the handlebars.

[0016] Furthermore, by forming the drainage wall 9B in a convex curved shape, small water droplets can be collected and quickly removed so that the water can flow more easily, and malfunctions caused by adhesion of water droplets can be further reduced. Note that the drainage wall 9B may be formed in an inverted V shape instead of a curved shape.

[0017] According to the above configuration, by forming the drainage wall 9B partially raised below the display area of ​​the display device 5 and outside the effective operation area of ​​the touch panel 4 related to the display screen of the display device 5, water droplets that have adhered due to gravity can be quickly removed without impairing the operation of the touch panel by the rider. This can reduce malfunctions caused by the adhesion of water droplets.

[0018] Furthermore, by forming the drainage wall 9B in a curved shape, small water droplets can be collected and quickly removed so as to facilitate flow, and malfunctions caused by adhesion of water droplets can be further reduced.

[0019] Furthermore, since the cover panel and the handle cover are integrated by two-color molding or bonding, it is possible to prevent foreign matter from entering the instrument housing.

[0020] Second Embodiment FIG. 3 is a plan view showing a display device according to a second embodiment of the present invention in comparison with FIG. This display device 11 is configured in the same way as the display device 1, except that the drainage wall 9B is formed in a curved shape that is concave toward the display 5. As a result, the display device 1 is provided with a drainage hole 9C at the center of the drainage wall 9B. Note that the drainage wall 9B may be made in a V-shape instead of a curved shape.

[0021] Even if the drainage wall 9B is formed in such a curved shape that is concave toward the display unit 5 side, the same effect as in the first embodiment can be obtained.

[0022] Third Embodiment FIG. 4 is a plan view showing a display device according to a third embodiment of the present invention in comparison with FIG. This display device 21 creates a display screen for the display device 5 by preventing operations of the touch panel 4 from being received by a plurality of horizontal electrodes on the lower side of the touch panel 4. As a result, the effective operation area of ​​the touch panel 4 related to the display screen of the display device 5 becomes smaller than that of the display device 1. In the display device 21, the effective operation area is smaller than that of the display device 1, so that the drainage wall 9B is formed at an upper position.

[0023] Even if the drainage wall 9B is formed at an upper position as in this embodiment, the same effects as in the first embodiment can be obtained.

[0024] [Fourth embodiment] FIG. 5 is a cross-sectional view showing a display device according to a fourth embodiment of the present invention in comparison with FIG. This display device 31 is formed so that the end of the housing 7 on the handle cover 9 side extends up to the handle cover 9, whereby a drainage wall 9B is provided at this extended portion of the housing 7.

[0025] Even if the drainage wall 9B is provided on the housing 7 in this manner, the same effects as those of the first embodiment can be obtained.

[0026] Other Embodiments The above describes in detail specific configurations suitable for implementing the present invention. However, the present invention allows the configurations of the above-described embodiments to be modified in various ways and even combined without departing from the spirit of the present invention.
