本発明は自動二輪車のハンドル支持構造に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handle support structure for a motorcycle.
従来この種の構造として、フロントフオークを
その上端部で連結する上ブラケツトに弾性部材例
えばゴム材を介して保持部材を挿着し、該保持部
材にハンドルを支持させるようにしたものがあ
る。 Conventionally, this type of structure includes a structure in which a holding member is inserted through an elastic member, such as a rubber material, into an upper bracket that connects the front fork at its upper end, and the handle is supported by the holding member.
これはハンドルを弾性的に支持してその振動を
防止するものであるが、この構造による防振効果
は弾性部材即ちゴム部材が柔らかいほど大きい。 This structure elastically supports the handle to prevent its vibration, and the vibration-proofing effect of this structure is greater as the elastic member, that is, the rubber member, is softer.
ところが、あまり柔らかいゴム材を使用すると
そのたわみ量が大きくなつてそれに支持された保
持部材が大きく振れることになり、その結果ハン
ドルがぐらついて不安定となる。 However, if a rubber material that is too soft is used, the amount of deflection will increase and the holding member supported by it will swing significantly, resulting in the handle wobbling and becoming unstable.
本発明は叙上事情に鑑みてなされたもので、そ

着部６b1に螺合するナツトである。 An example of the embodiment of the present invention will be explained with reference to the drawings. In Fig. 1, 1 is a front fork that supports a front wheel 2, 3 is a lower bracket that connects the front fork 1 at its middle part, and 4 is a front fork that connects the front fork 1 at its upper end. The upper bracket to be connected, 5 is a handle. Reference numeral 6 denotes a holding member inserted into the upper bracket 4 to support the handle 5, and its supporting structure is shown enlarged in FIG. The holding member 6 is divided into an upper member 6a and a lower member 6b, and the lower member 6b is inserted into the upper bracket 4. The insertion portion 6b1 of the lower member 6b is inserted into the insertion hole 4a of the upper bracket 4.
It has a shaft shape that fits loosely into the upper bracket 4, and its lower end protrudes below the upper bracket 4. Reference numeral 7 designates an inner cylinder that fits into the outer periphery of the insertion portion 6b 1 , and both upper and lower ends thereof protrude from the upper bracket 4. 8 is a washer that fits into the lower end of the insertion portion 6b 1 and engages with the lower end of the inner tube 7, and 9 is a nut that is screwed into the insertion portion 6b 1 on the lower side of the washer 8.

内外筒７，１１間にゴム材を射出してなる。この
弾性部材１０としてのゴム材は上ブラケツト４か
らの振動を有効に吸収し得るよう柔らかいものが
使用されている。 By tightening the nut 9, the inner cylinder 7 is connected to the washer 8 and the insertion portion 6 of the lower member 6b.
It is clamped and fixed between the flat part 6b 2 that continues on the upper end of b1 . 10 is an elastic member held between the inner cylinder 7 and an outer cylinder 11 provided on the outer periphery thereof;
A rubber material is injected between the inner and outer cylinders 7 and 11. A soft rubber material is used as the elastic member 10 so that vibrations from the upper bracket 4 can be effectively absorbed.
一方、前記外筒１１は内筒７よりも短い筒体で
あつて弾性部材１０を介して内筒７に一体に連結
され、上ブラケツト４の挿着孔４ａに圧入され

７が振れようとした場合にそれを係止して動きを
規制するようにする。 On the other hand, the outer cylinder 11 is a cylinder shorter than the inner cylinder 7, and is integrally connected to the inner cylinder 7 via an elastic member 10, and is press-fitted into the insertion hole 4a of the upper bracket 4 and fixed thereto. has been done. Furthermore, locking portions 12 are integrally formed at both upper and lower ends of the outer cylinder 11, respectively, protruding from the upper bracket 4. This locking part 12 is formed by curving both ends of the outer cylinder 11 inward by press molding or the like to narrow the diameter, and bringing the inner peripheral edge of the outer cylinder 11 close to the outer periphery of the inner cylinder 7 with a slight gap 1 therebetween. If it tries to swing, it will be locked and its movement will be restricted.
尚、上記係止部１２を外筒１１に一体的に形成
するに当つて、第３図に示す如く外筒１１の両端
に別部材である環状の円板１３を溶接するように
してもよい。 Incidentally, in forming the locking portion 12 integrally with the outer cylinder 11, annular discs 13, which are separate members, may be welded to both ends of the outer cylinder 11, as shown in FIG. .
一方、上側部材６ａは間にハンドル５の水平杆
部５ａを挾んで下側部材６ｂにボルト１４により
連結され、ハンドル５を固定するようにする。 On the other hand, the upper member 6a is connected to the lower member 6b with a bolt 14 with the horizontal rod portion 5a of the handle 5 interposed therebetween, so that the handle 5 is fixed.
斯くてハンドル５は上記保持部材６を介して上
ブラケツト４に支持される。 The handle 5 is thus supported by the upper bracket 4 via the holding member 6.
しかして、斯る支持構造とされたハンドル５は
上ブラケツト４からの振動が弾性部材１０によつ
て吸収されることによりその振動が防止される。 In the handle 5 having such a support structure, vibrations from the upper bracket 4 are absorbed by the elastic member 10, thereby preventing the vibrations.
また、ハンドル５にそれを前後にぐらつかせる
ような力が作用した場合には保持部材６とともに
内筒７が振れようとするが、その際内筒７が外筒
１１の係止部１２に当つて係止されることにより
その動きが規制され、ハンドル５がぐらつくこと
はない。 Furthermore, when a force is applied to the handle 5 that causes it to wobble back and forth, the inner cylinder 7 tries to swing together with the holding member 6, but in this case, the inner cylinder 7 hits the locking part 12 of the outer cylinder 11. By locking the handle 5, its movement is restricted and the handle 5 does not wobble.
本発明は叙上の如く構成したので、内筒が振れ
ようとした場合にそれが外筒の係止部に係止され
て動きを規制されるから、ハンドルのぐらつきを
有効に防止することができる。 Since the present invention is configured as described above, when the inner cylinder tries to swing, it is locked by the locking part of the outer cylinder and its movement is restricted, so that it is possible to effectively prevent the handle from wobbling. can.
従つて、弾性部材として柔らかいゴム材等を使
用してもハンドルがぐらつくことがなく、防振効
果を向上させることができる。 Therefore, even if a soft rubber material or the like is used as the elastic member, the handle does not wobble, and the vibration damping effect can be improved.
依つて所期の目的を達成し得る。 Thus, the intended purpose can be achieved.
