【0006】 図3に示す如く、前記主クラッチレバー(17)は前記ハンドル(15)の把 手部である操作部(15a)近傍にレバーガイド板(21)を介し設けたもので 、該レバー(17)とともに副クラッチレバーであるオンレバー(22)及びオ フレバー(23)を並設している。前記主クラッチレバー(17)はレバーガイ ド板(21)のブラケット(21a)に固設する支軸(24)に基端筒軸(25 )を揺動自在に支持させると共に、該筒軸(25)に基端を固設するクラッチア ーム(26)先端をピン(27)及び支点越えリンク(28)を介して前記主ク ラッチ(18)のクラッチワイヤ(29)に連結させ、前記主クラッチレバー( 17)を前方の図1矢印方向に揺動操作して仮想線状態とするときワイヤ(29 )を引張って主クラッチ(18)を入つまりオンとするように構成している。As shown in FIG. 3, the main clutch lever (17) is provided in the vicinity of an operating portion (15a) which is a grip portion of the handle (15) via a lever guide plate (21). An on-lever (22) and an off-lever (23), which are sub clutch levers, are arranged in parallel with (17). The main clutch lever (17) has a support shaft (24) fixedly mounted on a bracket (21a) of a lever guide plate (21) swingably supporting a base end cylinder shaft (25) and at the same time, the cylinder shaft (25). ) Is connected to the clutch wire (29) of the main clutch (18) via a pin (27) and a fulcrum crossing link (28), and the main end of the clutch arm (26) is fixed to the main clutch. When the lever (17) is swung forward in the direction of the arrow in FIG. 1 to bring it into a virtual line state, the wire (29) is pulled to engage or disengage the main clutch (18).

【0007】 また、前記クラッチアーム(26)に軸(30)を固設すると共に、該軸(3 0)に遊転自在にオン動作用回転体(31)を嵌合させ、前記オンレバー(22 )に一体連結するワンタッチ部材であるレバーアーム(32)先端を前記回転体 (31)に当接係止するように設けている。前記オンレバー(22)はブラケッ ト(21a)の固定支軸(33)に基端筒軸(34)を揺動自在に支持させると 共に、該筒軸(34)に前記レバーアーム(32)基端を連結固定させ、前記主 クラッチレバー(17)のオフ時前記回転体(31)にレバーアーム(32)を 当接係止させてオンレバー(32)のオフ位置保持を図ると共に、該オンレバー (32)を下方の図1矢印方向に揺動操作して仮想線状態とするとき前記レバー アーム(32)で回転体(31)を持上げる状態に作用させて主クラッチレバー (17)をオン動作に切換えて主クラッチ(18)をオンとするように構成して いる。Further, the shaft (30) is fixed to the clutch arm (26), and the on-operation rotor (31) is fitted on the shaft (30) so as to freely rotate, so that the on-lever (22). The lever arm (32), which is a one-touch member integrally connected to the rotary body (31), is provided so as to abut and lock the rotary body (31). The on-lever (22) swingably supports a base end cylinder shaft (34) on a fixed support shaft (33) of the bracket (21a), and at the same time, the cylinder shaft (34) supports the lever arm (32) base. The ends are connected and fixed, and when the main clutch lever (17) is off, the lever arm (32) is abutted and locked to the rotating body (31) to hold the on-lever (32) in the off position, and the on-lever (32) is held. 32) swinging downward in the direction of the arrow in FIG. 1 to bring it into a virtual line state, the lever arm (32) acts to lift the rotating body (31) to turn on the main clutch lever (17). The main clutch (18) is turned on by switching to.

【0008】 なお、(35)は前記主クラッチレバー(17)のストッパーピンであり、ワ イヤ(29)の引張力で該ピン(35)にレバー(17)を当接係止させること によりそのオフ保持を、また該ピン(35)にクラッチアーム(26)を当接係 止させることによりそのオン保持を図るものである。Reference numeral (35) is a stopper pin of the main clutch lever (17), and the lever (17) is brought into contact with and locked by the pulling force of the wire (29). It is intended to hold it off and hold it on by bringing the clutch arm (26) into contact with the pin (35).

【0009】 本実施例は上記の如く構成するものにして、図1実線状態の如く各レバー(1 7)(22)の何れもがオフ位置の状態よりオンレバー(22)を同図破線矢印 方向にオン操作するとき、該オンレバー(22)の操作力は前記レバーアーム( 32)、回転体(31)、軸(30)、クラッチアーム(26)を介して主クラ ッチレバー(17)に伝わるもので、この際主クラッチレバー(17)の作用長 さである支軸(24)と軸(30)の軸間距離(L1)は一定で、オンレバー( 22)の当接作用長さである回転体(31)とレバーアーム(32)の接点部と 支軸(33)間の距離(L2)は、支軸(33)を中心としてレバーアーム(3 2)が上方へ揺動するに伴いその距離(L2)を順次小とさせる。そのため仮り に主クラッチレバー(17)のオン操作時の操作力を一定とする場合前記距離( L2)が小さくなる分オンレバー(22)の操作力を比例的に軽減できるもので 、該実施例の図4に示す如く前記リンク(28)の支点越え付近のワイヤ(29 )の引張力が最大となるような主クラッチレバー(17)の操作力の最大必要時 において、前記距離(L2)を最小とすることによって、前記オンレバー(22 )の操作力の軽減化が図れるものであり、つまり前記主クラッチレバー(17) の支点越え時にあってはオンレバー(22)の前記距離(L2)の関係をオフ位 置時より小とする程オンレバー(22)の操作力の軽減化が図れる。The present embodiment is configured as described above, and when the levers (17) and (22) are in the off position as shown by the solid line in FIG. 1, the on lever (22) is moved in the direction of the broken line arrow in the figure. The operation force of the on-lever (22) is transmitted to the main clutch lever (17) through the lever arm (32), the rotating body (31), the shaft (30) and the clutch arm (26) when it is turned on. At this time, the axial distance (L1) between the support shaft (24) and the shaft (30), which is the working length of the main clutch lever (17), is constant, and the rotation length is the contact working length of the on-lever (22). The distance (L2) between the contact point between the body (31) and the lever arm (32) and the support shaft (33) varies as the lever arm (32) swings upward about the support shaft (33). The distance (L2) is gradually reduced. Therefore, if the operating force at the time of turning on the main clutch lever (17) is constant, the operating force of the on-lever (22) can be proportionally reduced by the reduction of the distance (L2). As shown in FIG. 4, when the maximum operating force of the main clutch lever (17) is required to maximize the tensile force of the wire (29) near the fulcrum of the link (28), the distance (L2) is minimized. By doing so, the operating force of the on-lever (22) can be reduced, that is, when the fulcrum of the main clutch lever (17) is crossed, the relationship of the distance (L2) of the on-lever (22) is changed. The operating force of the on-lever (22) can be reduced by making it smaller than that at the off position.
