Each handle holder 32 includes a holder lower portion (holder main body) 35 attached to the holder pedestal portion 31b and a holder upper portion (clamp member) 37 attached to the holder lower portion 35 with a pair of front and rear bolts 36 . The upper portion of the holder lower portion 35 cooperates with the holder upper portion 37 to form a half clamp structure. The steering wheel 2 has a straight pipe portion 2a extending in the vehicle width direction at the center portion in the vehicle width direction. The upper portion of the holder lower portion 35 and the holder upper portion 37 face each other across the straight pipe portion 2a of the handle 2 in the radial direction and sandwich the straight pipe portion 2a. In this state, the upper portion of the holder lower portion 35 and the holder upper portion 37 are fastened with a pair of front and rear bolts 36 to fix the straight pipe portion 2a and the handlebar 2 by extension. For example, the left and right holder upper portions 37 are connected by a connecting portion 37c extending in the vehicle width direction. For example, the left and right holder upper portions 37 and the connecting portions 37c are integrally formed with each other. Reference numeral 36a in FIG. 4 indicates a cap attached to the head of the bolt 36. As shown in FIG.

The holder lower portion 35 includes a holder body portion 41 cast from, for example, an aluminum alloy, and a fastening bolt 42 that is cast into the holder body portion 41 and has a shaft portion 42 a projecting from the holder body portion 41 .

The lightening portion 41c is formed so as to extend along the longitudinal direction of the holder main body portion 41 to reduce the weight of the holder lower portion 35. As shown in FIG.

The handle clamping portion 41a is disposed between a pair of front and rear mounting surfaces 41d which are planes orthogonal to the axial direction of the bolt 36 and the front and rear mounting surfaces 41d. and a semi-circular groove 41e forming a semi-cylindrical inner peripheral surface to match the lower half. An upper end of a female screw portion 41j for tightening the bolt 36 is opened in each mounting surface 41d.

The holder upper portion 37 functions as a handle clamping portion 37a paired with the handle clamping portion 41a of the holder lower portion 35 . The handle clamping portion 37a is disposed between a pair of front and rear mounting surfaces 37b, which are flat surfaces facing the front and rear mounting surfaces 41d of the handle clamping portion 41a, and the front and rear mounting surfaces 37b. and a semi-circular groove 37d forming a semi-cylindrical inner peripheral surface to match the upper half of the surface. For example, one of the front and rear mounting surfaces 37b contacts the facing mounting surface 41d, and the other of the front and rear mounting surfaces 37b forms a gap with the facing mounting surface 41d.

A lower end of a bolt insertion hole 37f through which the bolt 36 is inserted is opened in each mounting surface 37b. By inserting the bolts 36 into the respective bolt insertion holes 37f and screwing the respective bolts 36 into the female threads 41j of the holder body 41 and tightening them, the straight pipe portion 2a and thus the handle 2 are attached to the holder lower portion 35 and the holder upper portion 37. fixed to

The top bridge attachment portion 41b of the holder main body portion 41 has an enlarged portion 41b1 whose cross-sectional shape is enlarged with respect to the vertically intermediate portion of the holder main body portion 41. As shown in FIG. In the enlarged portion 41b1 and thus the top bridge mounting portion 41b, the lower end surface 41b2, which is a plane perpendicular to the axial direction of the fastening bolt 42, is parallel to the upper end surface 31b1 of the holder base portion 31b of the top bridge 31. That is, the upper end surface 31b1 of the holder pedestal portion 31b is a plane perpendicular to the axial direction of the fastening bolt 42 .

The top bridge mounting portion 41b of the holder body portion 41 includes a bolt enclosing portion (projection) 41f protruding downward from a lower end surface 41b2 of the top bridge mounting portion 41b so as to surround the shaft portion 42a of the fastening bolt 42. A lower end surface (tip surface) of the bolt enclosing portion 41f serves as an end surface (surrounding surface) 41h that presses an end surface 44c of a rubber member 44, which will be described later. A lower end surface 41b2 of the top bridge mounting portion 41b is a base surface (far surface) 41g that is further from the fastening bolt 42 than the bolt surrounding portion 41f, especially on the front side and the rear side of the bolt surrounding portion 41f. The bolt surrounding portion 41f is provided so as to protrude in the axial direction of the fastening bolt 42 from the base surface 41g.

An upper end surface 31b1 of the holder pedestal portion 31b of the top bridge 31 is parallel to and has the same shape as the lower end surface 41b2 of the top bridge mounting portion 41b. The upper end surface 31b1 of the holder pedestal portion 31b and the lower end surface 41b2 of the top bridge mounting portion 41b are separated from each other in the axial direction of the fastening bolt 42 . A flat rubber member (elastic member) 48 is arranged and sandwiched between the upper end surface 31b1 of the holder pedestal portion 31b and the lower end surface 41b2 of the top bridge mounting portion 41b.

The holder pedestal portion 31b has a concave portion 31c1 that opens upward and into which the rubber member (upper surface side elastic member) 44 is inserted, and a pair of front and rear positioning concave portions that are arranged on the front and rear sides of the concave portion 31c1 and open upward. (engaged portion) 31d.
On the lower side of the holder base portion 31b of the top bridge 31, there is provided a concave portion 31c2 that opens downward and into which a rubber member (lower surface side elastic member) 45 is inserted.

For example, the recessed portion 31c1 on the upper surface side of the top bridge 31 and the recessed portion 31c2 on the lower surface side are symmetrical with respect to a plane of symmetry perpendicular to the axial direction of the fastening bolt 42 . For example, the concave portion 31c1 on the upper surface side and the concave portion 31c2 on the lower surface side are rotationally symmetrical with respect to the axial direction of the fastening bolt 42 . The recessed portion 31c1 on the upper surface side and the recessed portion 31c2 on the lower surface side may have shapes different from each other, or may have shapes that are not rotationally symmetrical. The rubber members 44 and 45 inserted into the recess 31c1 on the upper surface and the recess 31c2 on the lower surface have substantially the same shape as the internal spaces of the recesses 31c1 and 31c2. In the embodiment, the rubber members 44 and 45 are given different symbols for identification, but they may be the same parts.

A through hole 31f through which the shaft portion 42a of the fastening bolt 42 is inserted is formed in the wall portion between the recess 31c1 on the upper surface side and the recessed portion 31c2 on the lower surface side of the top bridge 31 . The shaft portion 42a of the fastening bolt 42 is inserted through the through hole 31f. A gap is formed between the through hole 31 f and the shaft portion 42 a of the fastening bolt 42 . As a result, the handlebar holder 32 rubber-mounted to the top bridge 31 and thus the handlebar 2 can be moved, and the vibration damping effect of the handlebar 2 can be obtained.

Each of the recesses 31c1 and 31c2 has, for example, a bowl shape. That is, the inner peripheral surfaces of the recesses 31c1 and 31c2 are curved such that the cross-sectional area gradually increases from the bottom 31h toward the opening 31j. Along with this, the outer peripheral surfaces of the rubber members 44 and 45 are formed to have substantially the same shape as the inner peripheral surfaces of the respective recesses 31c1 and 31c2, or to have substantially similar shapes with an amount of bending taken into account. When the handle holder 32 is attached to the top bridge 31, the rubber members 44, 45 are fitted in the corresponding recesses 31c1, 31c2 in alignment.

A rubber member 48 separate from the rubber members 44 and 45 is sandwiched between the top bridge 31 and the holder lower portion 35 . The rubber member 48 has a flat plate shape having substantially the same shape as the lower end surface 41b2 of the top bridge mounting portion 41b. The rubber member 48 has a through hole 48a through which the bolt surrounding portion 41f of the holder main body 41 is inserted, and a plurality of projections (engagement portions) protruding from the lower surface 48b so as to be inserted into the plurality of positioning recesses 31d of the top bridge 31. 48c and.

Through holes 44b and 45b are formed in the rubber members 44 and 45 along the axial direction of the fastening bolt 42 .
The fastening bolt 42 passes through the through hole 44b of the rubber member 44, through the through hole 48a of the rubber member 48, and through the rubber member through hole 45b of the rubber member 45 in this order, and further passes through the washer 51 to connect the male screw portion 42b to the nut. 53 are screwed together.

When the nut 53 is tightened, the tip surface (surrounding surface) 41h of the bolt surrounding portion 41f of the holder main body 41 presses the upper end surface of the rubber member 44, and the base surface 41g of the holder main body 41 pushes against the rubber member 48. It presses the upper surface 48d. Thereby, the holder lower part 35 is elastically supported with respect to the top bridge 31 in a state where the rubber members 44, 45 and the rubber member 48 are compressed.

The outer diameter of the tip surface 41h of the bolt enclosing portion 41f is smaller than the inner diameter of the opening 31j of the recess 31c1 on the upper surface 31a side. This prevents the bolt surrounding portion 41 f from interfering with the top bridge 31 . Also, the washer 51 forming the bearing surface of the nut 53 is set to be spaced downward from the lower surface 31e of the top bridge 31, and interference with the top bridge 31 is suppressed. As a result, the handlebar holder 32 rubber-mounted to the top bridge 31 and thus the handlebar 2 can be moved, and the vibration damping effect of the handlebar 2 can be obtained.

As described above, the tip surface 41h and the base surface 41g of the holder main body 41 press the different rubber members 44 and 48, respectively. Hereinafter, the tip surface 41h and the base surface 41g may be collectively referred to as an end surface 41x of the top bridge attachment portion 41b.
The area of the base surface 41g is larger than the area of the tip surface 41h, and the surface pressure acting on the rubber member 48 from the base surface 41g is smaller than the surface pressure acting on the rubber member 44 from the tip surface 41h. Therefore, the deflection of the flat plate-like rubber member 48 is smaller than the deflection of the rubber members 44 and 45 around the fastening bolt 42 .

The rubber members 44 and 45 are easily compressed directly by the axial force of the fastening bolt 42, and the rubber members 44 and 45 are sufficiently pressed into the corresponding recesses 31c1 and 31c2 to ensure the supporting rigidity of the holder lower portion 35. Cheap. Since the rubber member 48 is farther forward and rearward from the fastening bolt 42 than the rubber members 44 and 45, it is easy to suppress tilting of the holder lower portion 35 (especially tilting in the front-rear direction) even if the compression is small. For example, the rubber member 48 can have different characteristics such as being harder than the rubber members 44 and 45, and the degree of freedom in setting the rubber mount of the handle 2 can be increased.

As described above, the handle holder mounting structure in the above embodiment includes the handle holder 32 that supports the handle 2 at one end and is attached to the top bridge 31 at the other end. Concave portions 31c1 and 31c2 are formed in the handle holder 31e, respectively. A fastening bolt 42 protrudes from the other end, the fastening bolt 42 penetrates the rubber member 44, the top bridge 31 and the rubber member 45, and a nut 53 is tightened to the tip of the fastening bolt 42. The handle holder 32 is attached to the top bridge 31, and a rubber member 48 is arranged around the fastening bolt 42 so as to be sandwiched between the top bridge 31 and the handle holder 32. Of the end faces 41x of the other end of 32, a tip face 41h arranged so as to surround the fastening bolt 42 abuts on the rubber member 44 and is a base face farther from the fastening bolt 42 than the tip face 41h. 41 g contacts the rubber member 48 .

According to this configuration, even if the handlebar 2 is enlarged, for example, the handlebar holder 32 supporting the handlebar 2 has a rubber end surface 41h surrounding the fastening bolt 42 at the end surface 41x of the other end attached to the top bridge 31. Not only is it supported in contact with the member 44 , but also the base surface 41 g distant from the fastening bolt 42 is supported by the top bridge 31 via the rubber member 48 . For this reason, the handle holder 32 can be elastically supported while its support rigidity is increased, and the handle holder 32 can be stably and elastically supported even when the handle 2 is enlarged.

Further, in the handle holder mounting structure, the rubber member 48 has a projection 48c that engages with the top bridge 31, the top bridge 31 has a positioning recess 31d that engages with the projection 48c, and the projection 48c and the positioning recess 31d engage with each other, the rubber member 48 is positioned on the top bridge 31. Therefore, when the rubber member 48 is assembled to the top bridge 31, positioning of the rubber member 48 is facilitated. It can be carried out.

In addition, in the handle holder mounting structure, since the rubber member 48 is formed in a flat plate shape, it is easy to dispose the rubber member 48 between the top bridge 31 and the handle holder 32, and the manufacturing cost of the rubber member 48 is low. can be reduced.

In the handle holder mounting structure, the handle holder 32 has an annular bolt surrounding portion 41f protruding in the axial direction of the fastening bolt 42 so as to surround the fastening bolt 42 at the other end. 32 is the tip end surface 41h of the bolt enclosing portion 41f, the bolt enclosing portion 41f protruding from the other end of the handle holder 32 avoids the upper surface 31a of the top bridge 31 and the rubber member 44 , 45 can be provided with a fastening force. A base surface 41g separated from the bolt surrounding portion 41f can be supported by the upper surface 31a of the top bridge 31 via a rubber member 48. As shown in FIG.

In addition, in the handle holder mounting structure, the rubber member 48 has a through hole 48a through which the bolt enclosing portion 41f penetrates. , a pressing force can be applied from the handle holder 32 to the rubber member 48, and the degree of freedom in setting the elastic support of the handle holder 32 can be increased.

In the handlebar holder mounting structure, the outer diameter of the bolt enclosing portion 41f is smaller than the inner diameter of the opening 31j of the recess 31c1 into which the rubber member 44 is inserted. Interference with the surrounding portion 41f can be suppressed, and the structure can be such that vibrations are not directly transmitted from the top bridge 31 side to the handlebar holder 32.

In the handle holder mounting structure, the outer peripheral shapes of the rubber members 44 and 45 and the inner peripheral shapes of the recesses 31c1 and 31c2 on the upper surface 31a side and the lower surface 31e side of the top bridge 31 are determined by the fastening bolt 42. The rubber member 44 is formed to increase in diameter from one end side (bottom portion 31h side) to the other end portion side (opening portion 31j side) facing each other in the axial direction of . , 45 and the recesses 31c1 and 31c2 of the top bridge 31 are aligned with each other, so that the tapered rubber members 44 and 45 are similarly aligned and fastened in the tapered recesses 31c1 and 31c2. The support rigidity can be increased while elastically supporting the handle holder 32 . Further, the tapered rubber members 44, 45 and the concave portions 31c1, 31c2 of the top bridge 31 can be easily formed.

The present invention is not limited to the above embodiments. For example, the shape of the inner peripheral surface of the recess formed on the upper and lower surfaces of the top bridge and the outer peripheral surface of the rubber member may be a cone, a truncated cone, a pyramid, or a truncated pyramid. Alternatively, shapes similar to these shapes may be used. The positioning structure between the top bridge and the rubber member may replace the unevenness.
The straddle-type vehicle to which the present invention is applied includes all vehicles in which the driver rides across the vehicle body, not only motorcycles (including motorized bicycles and scooter-type vehicles), but also three-wheeled vehicles (one front wheel and one rear wheel). In addition to two-wheeled vehicles, vehicles with two front wheels and one rear wheel are also included) or four-wheeled vehicles.
Vehicles other than saddle-riding vehicles (passenger cars, buses, trucks, bicycles, etc.), aircraft, ships, boats, yachts, marine bikes, and the like are conceivable as other transportation equipment to which the present invention is applied.

In the present embodiment, the top bridge of the steering system component of a saddle-ride type vehicle is exemplified as the operated member of the present invention, but the present invention is not limited to this. For example, the operated member may be a steered member that is separated from the steered wheels, the front forks, and the like and that is interlocked therewith.
The handle supported by the handle holder is not limited to a left and right integrated bar handle, but may be a separate left and right handle, and may not be of the bar type.
The steering wheel holder mounting structure of this embodiment is applied to a vehicle, but the present invention is not limited to application to a vehicle. For example, the present invention may be applied to various transportation equipment such as aircraft and ships, and various vehicles such as construction machinery and industrial machinery. Furthermore, the present invention can be widely applied to devices other than vehicles as long as they are equipped with a handle holder, such as hand-push lawn mowers and cleaners.
The configuration in the above embodiment is an example of the present invention, and various modifications, such as replacing the constituent elements of the embodiment with known constituent elements, are possible without departing from the gist of the present invention.
