Japanese Utility Model Publication No. 63-98890

  By the way, if the structure around the head pipe of the saddle riding type vehicle is complicated, the weight of the saddle riding type vehicle may be increased, and the cost may be increased due to an increase in the number of parts and the number of manufacturing processes. In addition, a space for operating the handle stopper structure is limited around the head pipe, and the prescribed range of the rotation angle of the handle may be restricted by the space.

  Accordingly, the present invention simplifies the structure around the head pipe of the saddle riding type vehicle, thereby reducing the weight of the saddle riding type vehicle and reducing the number of parts and the number of manufacturing processes, and reducing the cost. An object of the present invention is to efficiently secure a space for operating the handle stopper structure around the periphery and to easily widen the specified range of the rotation angle of the handle.

  In order to solve the above problems, a saddle-ride type vehicle according to one aspect of the present invention has a vehicle body frame having a head pipe extending in the vertical direction, and a handle fixed in a state of being rotatably supported by the head pipe. A steering member having a steering shaft and a steering bracket fixed to the steering shaft in a state of being disposed on one side in the axial direction of the head pipe, an in-vehicle device supported by the body frame, and the head pipe A stay member that protrudes outward in a direction perpendicular to the axial direction of the head pipe and to which the in-vehicle device is attached, and the steering bracket is a restriction that comes into contact with the stay member when the handle rotates a predetermined angle The stay member has a shape in which the vertical dimension is larger than the width dimension and Restricting the rotation angle of the serial steering wheel.

  According to the above configuration, the stay member supports the in-vehicle device and restricts the rotation angle of the handle, so that the bracket for attaching the in-vehicle device to the vehicle body frame and the handle stopper structure are separately provided. The structure around the head pipe of the saddle riding vehicle can be simplified, the weight of the saddle riding vehicle can be reduced, and the cost can be reduced by reducing the number of parts and the number of manufacturing processes. Further, since the stay member has a shape in which the vertical dimension is larger than the width dimension, a wide space can be secured around the head pipe when the handle is rotated by a predetermined angle. Thus, it is possible to efficiently secure a space for operating the handle stopper structure and to easily widen the prescribed range of the rotation angle of the handle.

  The stay member may be formed in the head pipe and extend in the axial direction.

  According to the above configuration, since the stay member formed on the head pipe extends in the axial direction of the head pipe, for example, even if the load of a heavy object supported by the stay member reaches the stay member in the axial direction, the stay member The strength of the stay member is ensured so that heavy objects can be stably supported by the member, and the design freedom of the saddle riding type vehicle is increased while efficiently securing the space for operating the handle stopper structure around the head pipe. It is done.

  The head pipe has a first support portion that supports the steering shaft, and an outer peripheral surface that is located on the outer side of the direction perpendicular to the axial direction of the head pipe than the outer peripheral surface of the first support portion; A second support portion that supports the steering shaft adjacent to the first support portion in the axial direction; and a step portion formed between the first support portion and the second support portion; The stay member may be continuously formed on the first support portion, the stepped portion, and the second support portion.

  According to the above configuration, the stay member is formed on the head pipe continuously on the first support portion, the step portion, and the second support portion, so that the stay member is formed on the head pipe on the outer circumferential surface that is flat in the axial direction. Compared to the case, the length of the portion of the head pipe where the stay member is formed can be secured longer, and the strength of the head pipe and the stay member can be increased.

  When the handle is rotated by the predetermined angle, a side portion of the stay member formed on the second support portion may abut on the restriction portion.

  According to the above configuration, the stay member of the head pipe is formed at the contact portion between the stay member and the restricting portion by the side portion of the stay member formed on the second support portion contacting the restricting portion. Can be brought closer. Therefore, it is possible to easily ensure the strength that can withstand the impact of the stay member and the restricting portion coming into contact with the portion of the head pipe where the stay member is formed.

  The vehicle body frame includes a main frame portion that extends rearward from the first support portion, and the axis of the head pipe of the second support portion that is separated from the main frame portion and one side in the axial direction of the head pipe. A reinforcing member disposed outside the direction orthogonal to the direction, and the second support portion is disposed on one axial side of the head pipe with respect to the first support portion, and the stay member However, it may be provided in the front region of the head pipe, and the restricting portion may protrude upward from the front region of the steering bracket.

  According to the above configuration, since the restricting portion protrudes upward from the front region of the steering bracket, the rear portion of the steering bracket is compared with the case where the restricting portion protrudes upward from the rear region of the steering bracket. The position can be prevented from being restricted by the restricting portion. As a result, the distance between the rear region of the steering bracket and the reinforcing member is increased, and when the handle is rotated, the rear region of the steering bracket is less likely to hit the reinforcing member. Can be spread easily.

  The stay member may be a plate member extending in the vertical direction and in a direction orthogonal to the axial direction.

  According to the above configuration, the stay member can be brought into contact with the restricting portion at a portion extending in the vertical direction and in a direction orthogonal to the axial direction, so when the stay member and the restricting portion come into contact with each other, It is possible to prevent the surface pressure from concentrating locally on the stay member.

  According to the present invention, by simplifying the structure around the head pipe of the saddle riding type vehicle, the weight of the saddle riding type vehicle can be reduced, and the cost can be reduced by reducing the number of parts and the number of manufacturing processes. A space for operating the handle stopper structure around the pipe can be efficiently secured, and the specified range of the rotation angle of the handle can be easily expanded.

The cowl 10 and the headlamp device 11 are fixed to the front frame portion 13d.

  The under bracket 16 has a pair of restricting portions 16a that come into contact with the stay member 6 when the handle 9 is rotated by a predetermined angle. The under bracket 16 is separated from the reinforcing frame portions 2c and 2d and the reinforcing member 12 in the front-rear direction. When the handle 9 is rotated within the specified range of the rotation angle of the handle 9, the under bracket 16 does not interfere with any of the reinforcing frame portions 2c, 2d and the reinforcing member 12, and the circumferential direction of the head pipe 2a To turn.

  The head pipe 2a has a first support portion 2h, a second support portion 2i, and a step portion 2j. The first support portion 2 h extends in the axial direction X and supports the steering shaft 15. The second support part 2i has an outer peripheral surface located outside the outer peripheral surface of the first support part 2h in the orthogonal direction, and supports the steering shaft 15 adjacent to the first support part 2h in the axial direction X. . The 2nd support part 2i is arrange | positioned in the position of the axial direction X of the head pipe 2a rather than the 1st support part 2h at least one side (here upper side and lower side). The step portion 2j is formed between the first support portion 2h and the second support portion 2i.

  The 2nd support part 2i may be provided only in the position of the one side of the axial direction X of the 1st support part 2h of the head pipe 2a. Further, the head pipe 2a may not have the first support portion 2h, the second support portion 2i, and the step portion 2j, and may have, for example, a flat outer peripheral surface in the axial direction X. The head pipe 2a may be formed of a casting in which the first support portion 2h, the second support portion 2i, and the step portion 2j are integrated.

  The main frame portion 2b is connected to the first support portion 2h and extends rearward from the first support portion 2h. The reinforcing frame portions 2c and 2d are connected to the first support portion 2h at positions separated from the connecting portion between the first support portion 2h and the main frame portion 2b in the axial direction X, and extend rearward from the first support portion 2h. Are connected to the main frame portion 2b. The reinforcing member 12 is disposed on the outer side in the orthogonal direction so as to be separated from the main frame portion 2b on one side (here, the lower side) in the axial direction X.

  The stay member 6 is located below the upper bracket 17 and extends in the axial direction X and in a direction orthogonal to the axial direction X through the axis of the head pipe 2a. The stay member 6 is formed continuously with the first support portion 2h, the step portion 2j, and the second support portion 2i. The stay member 6 is provided with at least one attachment portion 6 a for attaching the cowl 10 and the in-vehicle device to the stay member 6. Specifically, the stay member 6 has a stay upper part 6b and a stay lower part 6c. The stay upper portion 6b is formed in the first support portion 2h. Two attachment portions 6a are arranged side by side in the axial direction X on the stay upper portion 6b. A plate portion 13e is fixed to the attachment portion 6a using a fastening member. The stay lower portion 6c extends downward from the stay upper portion 6b. The stay lower portion 6c has a contact portion 6d that contacts the restriction portion 16a when the handle 9 is rotated by a predetermined angle. Here, the abutting portion 6d is a side portion of a portion of the stay member 6 formed on the second support portion 2i.

  The dimension of the stay member 6 in the axial direction X can be appropriately set to a value within a range where the stay member 6 does not interfere with the under bracket 16 and the upper bracket 17. As an example, the dimension of the stay member 6 in the axial direction X is preferably in the range of 10% to 90% of the distance between the under bracket 16 and the upper bracket 17 in the axial direction X, and is 30% to 70%. A value in the range is more desirable, and a value in the range from 40% to 60% is more desirable.

  Further, the position of the stay member 6 in the axial direction X of the head pipe 2a can be set as appropriate, but as an example, the central position of the stay member 6 in the axial direction X is greater than the central position of the head pipe 2a in the axial direction X. It is desirable to form the stay member 6 on the head pipe 2a so that the contact portion 6d can be brought closer to the restricting portion 16a.

  Further, the position in the axial direction X of the mounting portion 6a in the stay member 6 can be set as appropriate, but as an example, the position in the axial direction X of at least one mounting portion 6a is the center position in the axial direction X of the stay member 6 If the mounting portion 6a is formed on the stay member 6 so as to be further upward, it is desirable because the size of the plate portion 13e in the axial direction X can be reduced and the peripheral structure of the head pipe 2a can be easily simplified.

  FIG. 3 is a perspective view of the steering member 5 shown in FIG. FIG. 4 is a perspective view of the under bracket 16 of FIG. As shown in FIGS. 3 and 4, the under bracket 16 and the upper bracket 17 extend in the left-right direction. A steering shaft fixing portion 16 b that fixes the lower end portion of the steering shaft 15 to the under bracket 16 is provided at a position in the center in the left-right direction of the under bracket 16. Front fork fixing portions 16 c for fixing the front fork 7 to the under bracket 16 are provided at positions on both sides in the left-right direction of the steering shaft fixing portion 16 b of the under bracket 16. A front end surface 16d located on the front side of the front fork fixing portion 16c of the under bracket 16 is located forward of a front end surface 16e located on the front side of the steering shaft fixing portion 16b of the under bracket 16. Further, the rear end surface 16 f located on the rear side of the front fork fixing portion 16 c of the under bracket 16 is located in front of the rear end surface 16 g located on the rear side of the steering shaft fixing portion 16 b of the under bracket 16.

  The pair of restricting portions 16a has a left-right distance between the steering member 15 and the stay member 6 on both left and right sides of the steering shaft 15 in a state where the turning angle of the handle 9 is set to an angle at which the saddle riding type vehicle 1 advances straight. It is provided at a position of the under bracket 16 that is equidistant from each other. The restricting portion 16 a protrudes upward from the front region 16 h of the under bracket 16. The restricting portion 16a has a side surface 16a1 extending in the axial direction X and in a direction orthogonal to the axial direction X through the axial center of the head pipe 2a. The side surface 16a1 contacts the side surface 6d1 of the stay member 6 when the handle 9 is rotated by a predetermined angle (see FIG. 5). The rear region 16 i of the under bracket 16 is separated from the reinforcing member 12 and the reinforcing frame portions 2 c and 2 d within a specified range of the rotation angle of the handle 9.

  A steering shaft fixing portion 17 a that fixes the other axial end of the steering shaft 15 to the upper bracket 17 is provided at the center in the left-right direction of the upper bracket 17. Front fork fixing portions 17 b for fixing the upper end portion of the front fork 7 to the upper bracket 17 are provided at positions on both sides in the left-right direction of the steering shaft fixing portion 17 a of the upper bracket 17.

  The stay member 6 has a shape in which the vertical dimension is larger than the width dimension. The dimension in the width direction of the stay member 6 here refers to the left and right sides of the stay member 6 as viewed from the direction in which the axial center of the head pipe 2a and the apparent center position of the stay member 6 overlap in the orthogonal direction. Refers to the directional dimension. As an example, the stay member 6 is a plate member having a plate surface perpendicular to the width direction. The plate surface of the stay upper portion 6b and the plate surface of the stay lower portion 6c are formed flush with each other. The attachment portion 6a is provided with an insertion hole through which the stay member 6 is inserted in the width direction.

  The stay member 6 has a base portion 6e and a tip portion 6f. The base 6e is disposed at a position closer to the head pipe 2a in the orthogonal direction than the contact portion 6d of the stay lower portion 6c. The front end portion 6f is disposed at a position farther from the head pipe 2a in the orthogonal direction than the mounting portion 6a of the stay upper portion 6b. The base 6e is disposed at a position closer to the head pipe 2a in the orthogonal direction of the head pipe 2a than the tip 6f.

  FIG. 5 is a partial front view of the stay member 6 of FIG. FIG. 5 shows a partial front view of the stay member 6 when the stay member 6 comes into contact with the restricting portion 16a. As shown in FIG. 5, the contact portion 6d of the stay member 6 has a side surface 6d1 that extends in the axial direction X and through the axis of the head pipe 2a in a direction orthogonal to the axial direction X. The side surface 6d1 of the contact portion 6d and the side surface 16a1 of the restricting portion 16a are flat surfaces and come into surface contact with each other when the handle 9 is rotated by a predetermined angle.

  As described above, according to the saddle riding type vehicle 1, the stay member 6 supports the in-vehicle device and restricts the rotation angle of the handle 9, so that the bracket for attaching the in-vehicle device to the vehicle body frame 2. Compared to the case where the handle stopper structure is provided separately, the structure around the head pipe 2a of the saddle riding type vehicle 1 is simplified, the weight of the saddle riding type vehicle 1 is reduced, and the number of parts and the number of manufacturing processes are reduced. The cost can be reduced.

  Here, if the head pipe is provided with a stopper member having a shape whose width direction dimension is greater than or equal to the vertical direction dimension, when the handle is rotated by a predetermined angle, the stopper member is brought into contact with the restricting portion to adjust the rotation angle of the handle. When a straddle-type vehicle is provided with a restricting handle stopper structure, it is difficult to secure a space around the head pipe where the restricting part can move when the handle is turned, and the specified range of the turning angle of the handle becomes narrow. There is a fear. On the other hand, in the saddle riding type vehicle 1, the stay member 6 has a shape in which the vertical dimension is larger than the width dimension, so that the space where the restricting portion 16a can move when the handle 9 is rotated by a predetermined angle. Can be secured widely around the head pipe 2a, a space for operating the handle stopper structure around the head pipe 2a can be efficiently secured, and the prescribed range of the rotation angle of the handle 9 can be easily widened.

  Further, by using the stay member 6 having a shape whose vertical dimension is larger than the width dimension, a space in which the restricting portion 16a can move around the head pipe 2a when the handle 9 is rotated by a predetermined angle is secured. Therefore, compared to the case where the stopper member is provided on the head pipe, the restricting portion 16a can be easily protruded upward from the front region 16h of the under bracket 16. In this way, by projecting the restricting portion 16a upward from the front region 16h of the under bracket 16, the under bracket 16 of the under bracket 16 can be compared with the case where the restricting portion 16a protrudes upward from the rear region 16i of the under bracket 16. It is possible to prevent the portion provided with the restricting portion 16a from approaching the reinforcing frame portions 2c and 2d. As a result, the distance between the rear region 16i of the under bracket 16 and the reinforcing frame portions 2c and 2d is increased, and when the handle 9 is rotated, the rear region 16i of the under bracket 16 is reinforced with the reinforcing member 12 and the reinforcing frame. It is possible to make it easier to expand the specified range of the rotation angle of the handle 9 by making it difficult to hit the portions 2c and 2d.

  Further, since the stay member 6 extends in the axial direction X, for example, even if the weight load of the in-vehicle device supported by the stay member 6 reaches the stay member 6 in the axial direction X, the stay member 6 It is possible to increase the degree of design freedom of the saddle riding type vehicle 1 while efficiently securing a space for operating the handle stopper structure around the head pipe 2a while securing the strength of the stay member 6 that can be stably supported. it can.

  Further, since the stay member 6 is formed on the head pipe 2a continuously to the first support portion 2h, the step portion 2j, and the second support portion 2i, the stay member is attached to the head pipe on the outer peripheral surface flat in the axial direction X. As compared with the case where the stay member 6 is formed, the length of the portion of the head pipe 2a where the stay member 6 is formed can be secured longer, and the strength of the head pipe 2a and the stay member 6 can be increased.

  In addition, since the abutment portion 6d formed on the second support portion 2i of the stay member 6 abuts on the restriction portion 16a, the stay member 6 of the head pipe 2a is located at the abutment portion between the stay member 6 and the restriction portion 16a. It is possible to approach the part where the is formed. Therefore, it is possible to easily ensure the strength to withstand the impact of the stay member 6 and the restricting portion 16a in contact with the portion of the head pipe 2a where the stay member 6 is formed.

  Further, since the stay member 6 is a plate member extending in the up-down direction and the orthogonal direction, the stay member 6 is brought into contact with the restricting portion 16a by contacting a portion of the stay member 6 extending in the up-down direction and the orthogonal direction. And the restricting portion 16a can be dispersed over the entire contact area of the side surfaces 16a1 and 6d1, and the surface pressure can be prevented from locally concentrating on the stay member 6.

  The portion of the head pipe 2a where the stay member 6 is formed is required to have a strength that can withstand the weight load of the in-vehicle device and a strength that can withstand the impact of the stay member 6 and the restricting portion 16a coming into contact. It is done. In the saddle riding type vehicle 1, a portion of the head pipe 2a where the stay member 6 is formed is secured long in the axial direction X, and the stay member 6 is formed on the head pipe 2a with high strength. Therefore, even if the weight load of the in-vehicle device or the impact of contact between the stay member 6 and the restricting portion 16a is applied to the portion of the head pipe 2a where the stay member 6 is formed, the stay member 6 or the head pipe 2a. It is possible to satisfactorily prevent the portion where the stay member 6 is formed from being damaged.

  Further, since the stay lower portion 6c having the contact portion 6d extends downward from the stay upper portion 6b, in order to provide the restricting portion 16a on the under bracket 16 so as to be able to contact the contact portion 6d, for example, The vertical dimension of the bracket 16 need not be increased. Therefore, an increase in the weight of the under bracket 16 can be prevented, and the under bracket 16 and the in-vehicle device can be separated in the vertical direction to prevent the under bracket 16 from interfering with the in-vehicle device.

  Further, since the plate surface of the stay member 6 is formed flush with the stay upper portion 6b and the stay lower portion 6c, the stay upper portion 6b and the stay lower portion 6c are brought into contact with each other when the stay member 6 and the restricting portion 16a come into contact with each other. It is possible to prevent the surface pressure from being concentrated locally between the stay upper part 6b and the stay lower part 6c, or the stay member 6 is bent between the stay upper part 6b and the stay lower part 6c.
