７′を有している。 The present invention will be described below with reference to embodiments shown in the drawings. In FIG. 1, 1 is a change lever;
2 is a power gear, 3 is a cam coaxially supported with the power gear, 4 is a first locking link, and 5 is a second locking link.
This is a lock link. Further, 100 is a gear that constantly rotates in a clockwise direction and meshes with the power gear 2. Furthermore, the power gear 2 has a slight rotational force so as to rotate in a counterclockwise direction.
A return spring 6 is engaged with the change lever 1, and by pushing it in the direction of the arrow, it can be moved against the bias force of the spring 6.

述するようなアイドラ切替機構の如きリールベー
スの駆動切替手段と係合していて、これにリバー
ス動作のための切替力を附与する。 The power gear 2 has an intermittent gear 16, and a pin 17' is provided eccentrically from the shaft 17, and a rotational force is applied to the pin to rotate the pin clockwise or counterclockwise. Pin 17' engages a reel-based drive switching means, such as an idler switching mechanism as described below, to provide a switching force for reverse operation.

ロツク状態となるから、パワーギヤ２は反時計方
向に回転し、間欠ギヤ１６とギヤ１００が係合し
て、反時計方向に回転する。 Now, when the change lever 1 is pushed in to some extent, the pin 12 leaves the pawl 7', and the second locking link 5 rotates clockwise and comes into contact with the cam 3 in the state shown in FIG. 2a. When the change lever 1 is pushed further, the claw portion 7 comes into contact with the pin 10, and the first locking link 4 rotates clockwise against the bias force of the spring 11. Therefore, the claw portion 9 is disengaged from the locking portion 15 of the cam 3, and the cam 3 is in the unlocked state, so that the power gear 2 rotates counterclockwise and the intermittent gear 16 and the gear 100 are rotated. engage and rotate counterclockwise.
パワーギヤ２が約半回転した時、該ギヤの間欠

込んだ場合でも同様である。 When the power gear 2 rotates approximately half a rotation, the engagement with the gear 100 is turned off due to the intermittent portion of the gear, but the power gear 2 rotates counterclockwise due to a slight rotational force. Therefore, the locking part 15 of the cam 3 is connected to the second locking link 5 in FIG.
The cam 3 is engaged as shown in FIG. Even if you keep pushing the change plate 1 in this state, the cam 3 is locked as described above, so the power gear 2
does not rotate. The same thing happens even when the change lever 1 is pushed in slowly.

る。 Next, when the change lever 1 begins to return, the claw 7 returns while still in contact with the pin 10, so the first locking link 4 rotates counterclockwise, as shown in Figure 2c. The claw part 9 is the locking part 1
It contacts the cam 3 with a slight gap l left between it and the cam 4. When the change lever 1 returns further, the claw portion 7' contacts the pin 12 and the second lock link 5
Since the cam 3 is rotated counterclockwise against the bias force of the spring 13, the cam 3 is released from the locking portion 15 and the cam 3 is unlocked. Therefore, at that time, the power gear 2 rotates slightly counterclockwise by the gap 1, the locking portion 14 of the cam 3 is locked with the claw portion 9 of the first locking link 4, and the cam 3 is locked.
