Description

  The present invention relates to a guard member.

  Conventionally, as a two-seater saddle riding type vehicle, there is a vehicle provided with a guard member that covers a rear wheel from the side (see, for example, Patent Document 1). This type of guard member prevents the passenger's clothes seated on the rear part of the seat from coming into contact with the rear wheel. Patent Document 1 describes a side cover that is formed of a frame material obtained by bending a pipe material and is arranged so as to cover the left side of the rear wheel.

JP2011-218971A

  By the way, when the guard member is arranged so as to cover both the left and right sides of the rear wheel, the swinging member and the exhaust system member are not increased without increasing the size in the vehicle width direction of the vehicle when the entire area of the guard member is increased. It is difficult to ensure a clearance for preventing members from interfering with each other. For this reason, when enlarging the conventional guard member, there is a problem in that the degree of freedom of design is restricted in order to ensure clearance.

  The present invention provides a guard member that can ensure a degree of freedom in design.

(1) The guard member according to one aspect of the present invention is a guard member (60, 80) that covers the side of the rear wheel (3) of the saddle-ride type vehicle (1), and the first wire rod (68, 86). ) Formed by the first outer frame (62, 82) and the first guard part (61, 81) and the second wire (76, 96) having a smaller diameter than the first wire (68, 86). ), And a second guard portion (71, 91) having a second outer frame (72, 92).

  According to the present invention, compared with the case where the guard member includes only the first guard portion, the area of the guard member can be increased by providing the second guard portion. Furthermore, the second outer frame of the second guard part is formed by the second wire having a smaller wire diameter than the first wire that forms the first outer frame of the first guard part. Compared to the case of forming with one wire, the clearance is easily secured without increasing the vehicle width of the vehicle. Therefore, it is possible to provide a guard member having a high degree of design freedom.

(2) In the guard member of the above aspect (1), the first outer frame (62, 82) may be provided with attachment portions (62d, 82e) to the vehicle body (20).

  By configuring as described above, the attachment portion is provided on the first wire having a larger wire diameter than the second wire, so that the guard member is compared with the case where the attachment portion to the vehicle body is provided on the second outer frame. The rigidity of the attachment structure to the vehicle body can be improved.

(3) In the guard member according to the above aspect (1) or (2), the second outer frame (72, 92) is located at a location facing inward in the vehicle width direction of the first outer frame (62, 82). It may be attached.

  By configuring as described above, the second outer frame can be attached to the second outer frame without increasing the amount of bending of the second outer frame, as compared with the case where the second outer frame is attached to a portion of the first outer frame facing outward in the vehicle width direction. The guard part can be brought close to the rear wheel. Thereby, it can suppress that the vehicle width of a saddle-ride type vehicle increases with a guard member.

(4) In the guard member according to the above aspect (3), the second outer frame (72, 92) may be welded to the first outer frame (62, 82).

  By configuring as described above, the second outer frame can be firmly attached to the first outer frame. Moreover, since the welding location of the 1st outer frame and the 2nd outer frame faces inward in the vehicle width direction, it becomes difficult to visually recognize from the side of the vehicle. Therefore, the appearance of the guard member can be improved.

(5) In the guard member according to any one of aspects (1) to (4), the first guard part (61, 81) may have a larger area than the second guard part (71, 91). .

  By comprising as mentioned above, the increase in the weight of a guard member can be suppressed to the minimum by using the 2nd guard part supplementarily, maintaining the intensity | strength as a guard member with the 1st guard part. Therefore, the guard member which can be reduced in weight can be provided.

(6) In the guard member according to any one of aspects (1) to (5), the second guard part (91) is disposed below the first guard part (81), and the first guard part ( 81) extends outward in the vehicle width direction from the top to the bottom of the vehicle, and at least a part of the second guard portion (91) extends outward in the vehicle width direction from the top to the bottom of the vehicle, The outer end (91r) in the vehicle width direction of the second guard portion (91) is more inward in the vehicle width direction than the outer end (81r) in the vehicle width direction of the first guard portion (81). May be located.

  By configuring as described above, the first guard portion and the second guard portion extend outward in the vehicle width direction from the upper side toward the lower side, so the first guard portion and the second guard portion interfere with the rear wheels and the like. Can be prevented. Further, the second guard portion is positioned inward in the vehicle width direction than the outer end portion in the vehicle width direction of the first guard portion, so that the second guard portion is positioned in the vehicle width direction. It can suppress that the vehicle width of a saddle-ride type vehicle protrudes outward and increases.

(7) In the guard member according to any one of (1) to (6), the second outer frame (92) is disposed on the exhaust part (44) side in the vehicle width direction with respect to the rear wheel (3). ) Has a bent portion (92d), extends inward in the vehicle width direction from the bent portion (92d) toward the lower side of the vehicle, and is lower than the bent portion (92d) in the second outer frame (92). At least a part of the portion may overlap the exhaust part (44) when viewed from the vehicle width direction inward in the vehicle width direction than the exhaust part (44).

  By configuring as described above, a portion below the bent portion in the second outer frame can be inserted between the rear wheel and the exhaust part. As a result, it is possible to extend the second guard portion to a position overlapping the exhaust part when viewed from the vehicle width direction while suppressing an increase in the vehicle width of the saddle-ride type vehicle. Further, since the second outer frame is formed of the second wire having a smaller diameter than the first wire, the second outer frame can be disposed even if the second outer frame is disposed between the exhaust part and the rear wheel. And interference with exhaust parts can be easily prevented.

(8) In the guard member according to the above aspect (7), the rear member (3) is disposed on the rear cushion (10) side in the vehicle width direction, and the bent portion (92d) extends from the front-rear direction of the vehicle. As seen, the rear cushion (10) may be located more outward in the vehicle width direction than the inner end in the vehicle width direction.

  By configuring as described above, compared to the case where the bent portion is positioned inward in the vehicle width direction than the inner end portion in the vehicle width direction of the rear cushion, the rear portion is rearward in the vehicle width direction outside the rear wheel. The second outer frame is disposed outward in the vehicle width direction relative to the rear cushion disposed at a position where it does not interfere with the wheel. Therefore, the interference between the second outer frame and the rear wheel can be prevented more reliably.

(9) In the guard member according to any one of (1) to (8), at least one of the first outer frame (62, 82) and the second outer frame (72, 92). An auxiliary member (66, 74, 84, 94) extending at least one end of the auxiliary frame (66, 74, 84, 94) connected to the one outer frame. May be formed of a third wire rod (69, 77, 87, 97) having a smaller wire diameter than the second wire rod (76, 96).

  By comprising as mentioned above, it can prevent that a passenger | crew's clothes contact a rear wheel inside one outer frame with an auxiliary member. And since the 3rd wire which forms an auxiliary member has a smaller wire diameter than the 2nd wire, compared with the case where the 3rd wire has a wire diameter more than the 2nd wire, it can lighten a guard member. it can.

  According to said guard member, the guard member which can ensure the freedom degree of design can be provided, without increasing the vehicle width of a vehicle.
