It was a factor to be damaged.

  In particular, in motorcycles equipped with a large windscreen, the air pressure is lower than the atmospheric pressure (negative pressure) behind the windscreen when driving at a high speed, so there was a negative pressure between the windscreen and the rider. The surrounding air was engulfed by negative pressure, causing unpleasant noise, and the wind hitting the rider's upper body, which was a factor that impaired comfort.

  In addition, in the handle cover device for a motorcycle described in Patent Document 1, an example in which an air vent hole is provided on the front surface of the handle cover is disclosed, but the opening portion of the air vent hole is substantially at the center of the handle grip. Since the opening faces the portion, there is a problem that the windproof, mudproof and gravelproof effects of the knuckle portion and arm portion of the rider may be impaired.

  The present invention has been made in consideration of the above-described circumstances, and has provided a wind guide path for the wind that strikes the front surface of the handle cover to the outside in the vehicle width direction, reduces the wind that strikes the rider, and travel comfort It is an object of the present invention to provide a handle cover device for a two-wheeled vehicle that maintains the above.

  Another object of the present invention is to provide an air vent hole in the handle cover covering the front side of the rider to reduce the unpleasant wind hitting the upper body of the rider, and to provide wind, mud, and gravel protection effects during traveling. An object is to provide a handle cover device for a motorcycle.

  In order to solve the above-described problems, a handle cover device for a motorcycle according to the present invention includes a wind screen at an upper portion of a cowling that covers a front upper portion of a vehicle body, and the handle is provided behind the wind screen and in front of a handle grip. In the case where a handle cover device is provided to cover the grip from the front, the handle cover device has a groove-shaped air guide path outside the vehicle width direction above the vehicle body side inclined surface of the handle cover in a front view. It is characterized by being extended in the direction.

  In the present invention, when the handle cover is viewed from the front, the groove cover-shaped air guide passage is configured to extend outward in the vehicle width direction above the inclined surface on the vehicle body side of the handle cover. The wind that hits the upper surface of the slanted surface of the car body escapes the wind that flows in the car body inside direction by the air guide path to the upper part of the car body outside direction, reducing the unpleasant wind hitting the upper body of the rider, and driving comfort It is something to keep.

As shown in FIG. 9, traveling wind acts on the handle cover 31 as viewed from above, and traveling wind that strikes the rear inclined upper surface portion of the vehicle body inner inclined surface of the handle cover 31 bends in the vehicle body inner direction D, and rider Guided to face the upper body.

  However, in the motorcycle 10 of the present embodiment, as shown in FIG. 10, the handle cover device 30 has a groove-shaped air guide path 47 and rib on the inclined surface upper part of the cover body 44 in the axial direction on the handle cover 31. Since the inclined wall 46 having the shape of a wall is provided, the traveling wind hitting the upper portion of the inner inclined surface (inward of the cover in the vehicle width direction) of the handle cover 31 flows in the vehicle body inner direction D through the air guide passage 47. The direction of the wind is changed to the vehicle body outer side direction E to escape to the upper part of the vehicle body upper direction, and the unpleasant wind strongly hitting the rider can be reduced, and the driving comfort can be improved.

  The handle cover device 30 has a concave groove-shaped air guide path extending in the vehicle width direction side from the center of the cover to the upper part of the vehicle body side inclined surface on the vehicle width direction inner side in the front surface of the handle cover 31 when viewed from the front. 47, and the wind that hits the upper part of the inclined surface on the inner side (vehicle body side) of the handle cover 31 changes the direction of the wind flowing in the vehicle body inner direction D through the air guide path 47 and escapes in the vehicle body outer direction E to the rider. The unpleasant wind that strikes strongly can be reduced. In that case, since the upper surface of the grooved air guide path 47 is configured with the inclined wall 46 in a wall shape or a bowl shape, the traveling wind can be more effectively released to the upper part in the vehicle body outer direction E, The wind hitting the rider can be further reduced, and the driving comfort can be further improved.

  Further, the handle cover device 30 is provided with air vent holes 45a and 45b in the vehicle body side base 40 of the handle cover 31 when the handle cover 31 is viewed from the front. You can circulate backwards, bypassing your hand. It is possible to relieve the wind force that flows toward the inside of the vehicle body of the traveling wind that has hit the upper surface (upper part) of the inclined surface of the vehicle body side of the handle cover 31.

  In a motorcycle equipped with a large windscreen 13, a negative pressure space C is generated between the windscreen 13 and the rider's upper body as shown in FIG. 11A when traveling at a high speed (80 km / h or more). However, since the generated negative pressure entrains the surrounding air, unpleasant noise is generated, the protection effect of the rider is reduced, and the comfort is impaired. However, in the present embodiment, air vent holes 45a and 45b are provided in the vehicle body side base 40 of the handle cover 31, and as shown in FIG. By flowing backward from the air vent holes 45a and 45b and flowing a small amount of air into the negative pressure space on the upper surface of the fuel tank 25 to relieve the negative pressure, it is possible to reduce the surrounding wind from being caught in the rider direction. .

  At this time, since the outer air vent 45a is disposed on the inner extension surface of the air guide passage 47 provided with the wall-shaped inclined wall 46 in the front view of the handle cover 31, the inner inclined surface of the handle cover 31 is provided. As shown in FIG. 10, the traveling wind that hits the upper surface of the vehicle escapes to the upper part on the outer side of the vehicle body and opens to both sides of the inclined wall 46 at the base portion 40 of the handle cover 31. By extracting the traveling wind from the wind vent holes 45a and 45b in a balanced manner toward the rear of the vehicle body, the wind force flowing in the vehicle body inner direction can be softened. For this reason, the unpleasant wind which hits a rider strongly can be reduced, and the comfort of driving | running | working can be improved.

  In this manner, the handle cover device 30 is caused to flow backward to the base portion 40 of the handle cover 31 through the air vent holes 45a and 45b, so that a slight wind flows into the negative pressure space on the upper surface of the fuel tank 25, and the negative pressure is relieved. Therefore, it is possible to reduce the entrainment of the surrounding traveling wind in the rider direction.

  The vent holes 45a and 45b provided in the handle cover 31 do not face the rider's hand, but are provided on the inner side of the vehicle body from the width of the handle grip 28. Therefore, the protection effect of the handle cover 31 that covers the hand of the rider can be sufficiently achieved, and the air vent holes 45a and 45b are provided with an air intake effect. Further, the handle cover 31 has inner attachment portions 41a and 41b attached at two positions between the upper and lower tightening portions, and is supported on the handle 20 side by the inner attachment portions 41a and 41b and the outer attachment portion 37. It has a mounting structure. For this reason, the handle cover 31 can be stably mounted while maintaining sufficient surface rigidity and stable mounting rigidity even in the case of synthetic resin manufacture.

  Forming the openings of the vent holes 45a and 45b in the base portion 40 of the handle cover 31 made of synthetic resin tends to cause a problem in terms of strength due to a decrease in surface rigidity. Since the air vent holes 45a and 45b are formed between the upper and lower inner mounting portions 41a and 41b to which the 40 is mounted, the mounting rigidity is sufficiently strong. Further, the air vent holes 45a and 45b are divided into two upper and lower portions, the size and shape of the opening area of both openings can be changed variously, and the mounting structure has a balance between the diversion effect and the rigidity and strength. .

  In the present embodiment, an example in which the handle cover device is applied to a motorcycle has been shown, but the handle cover device can also be applied to a scooter type vehicle or a bicycle.

  Further, the handle cover device has been described by taking the right handle cover covering the front of the right handle grip as an example. However, the left handle cover is provided symmetrically with the right handle cover, and therefore the handle cover device is also applicable to the left handle cover. Not too long. However, the right handle cover is attached to the front of the left handle grip so as to cover the left handle grip and the clutch lever from the front.
