構造も考えられているが、リンク機構が複雑で組付手数
もかかるものであった。 又、複雑なリンク機構はリン
ク支点でのこじりが生じやすく、耐久性にも多少の難点
があった。When using a gear shift mechanism equipped with multiple shift forks and using a single gear shift lever to perform gear shifting of 8 or more gears, the shift lever is generally moved along a J-shaped and H-shaped operating trajectory. However, the lever operation trajectory is complicated and difficult to operate. Therefore, it has been proposed to operate multiple fork shifts by sliding the cam plate linearly using the linear swing of the wooden gearshift lever, but this method causes wear on the sliding guide part of the cam plate and prevents smooth operation. There was a high risk of damage. Also, 1 that swings in a straight line
An operation structure has been considered in which a wooden gear shift lever and a plurality of shift forks are connected to each other through a link mechanism to eliminate linear sliding as much as possible, but the link mechanism is complicated and requires a lot of effort to assemble. In addition, the complicated link mechanism is prone to twisting at the link fulcrum, and has some drawbacks in durability.
本発明は係る実情に着目してなされたものであって1回
転カムの導入によって変速操作を摩耗やとじりの少い回
転のみで行えるようにし、1本の変速レバーによる多段
変速を直線操作で容易に行えるようにすることを目的と
するものである。The present invention was made in view of the above-mentioned circumstances, and by introducing a single-rotation cam, it is possible to perform gear shifting operations with only rotations with less wear and binding, and multi-speed shifting with a single gear lever can be performed in a linear manner. The purpose is to make it easier.

軸への操作系に増速用ギヤを介在しである点にあり、そ
の作用効果は次のようである。A feature of the great invention is that a cam follower that is connected to a plurality of shift forks is engaged with a rotary cam that can be rotated manually, and the plurality of shift forks are displaced in a predetermined pattern by one rotational operation of the cam. The present invention is constructed so that the gears can be shifted in eight or more steps, and a speed increasing gear is interposed in the operation system for the spindle of the @-rotating cam, and its effects are as follows.
つまり1回転カムで複数のカムフォロアを操作するので
直線スライドカム方式のように短期間のうちに摩耗によ
る作動不良が生じるおそれが少く、又、リンク機構方式
のように多数の連結支点がなく1回転操作力を伝達する
簡単な操作系を用いて長期間に亘って円滑確実に作動さ
せることができるようになった。In other words, since multiple cam followers are operated by a single rotation cam, there is less risk of malfunction due to wear over a short period of time, unlike with a linear slide cam system, and there is no need for multiple connecting fulcrums as with a link mechanism system, making one revolution possible. Using a simple operating system that transmits operating force, it has become possible to operate smoothly and reliably over a long period of time.
又、回転カムをギヤ増速して太きh回動角で作動させる
ようにしたので、変速レバーを大きく操作しなくてもカ
ムの勾配をゆるくして円滑にカムフォロアを所定量変位
操作することが可能となった。In addition, since the rotating cam is operated at a large rotation angle by increasing the speed of the gear, the slope of the cam is made gentler and the cam follower can be smoothly displaced by a predetermined amount without having to operate the gear shift lever greatly. became possible.
