'', the second body 21 is engaged with the second engaging portion 25e while returning slightly in the direction opposite to the arrow C, thereby locking the second body 21 in the operating position. As a result, the first switch 31 is closed and the low beam lamp circuit is energized. First controller 3
When the pulling force is removed, the first operator 3 is pushed by the spring 7 and the ball 8 and returns to its original position as shown by the solid line in FIG. Further, the first body 15 returns to the original position shown in FIG. 3 by the force of the spring 16.

(b) When changing from "low beam" to "off" When the first controller 3 is pulled up as described in section (a), the second body 21 moves to the arrow C through the same process.
Since the bent portion 26a of the spring 26 moves in the direction of arrow D due to the elastic force of the spring 26, it moves from the second engagement portion 25e to the section of the passage _S1 as shown in FIG. Since the engagement is released by moving to ``'', the second body 21 will move in the opposite direction of arrow C due to the elastic force of the spring 22 and return to its original position, except for the pulling force of the first operator 3. Upon returning, the first switch 31 is opened, and the bent portion 26a of the spring 26 moves to the first engagement portion 24d of the passage _S1 . At the same time, the first interlocking body 1

Then, as in item (a) above, the first switch 31 is closed, and the first locking mechanism 24 locks the second body 21 in this operating position.
Therefore, the first and second switches 31 and 44 are closed, and both the low beam circuit and the high beam circuit are energized.

(d) When changing from "high beam" to "low beam" When the second operator 4 is pulled up in the same way as in (c), the third body 32 is pushed slightly in the direction of arrow A, so the bent part of the spring 37 37a moves from the second engagement portion 36c to the passage _S2 in the direction of arrow E and releases its engagement, as described in section (b), due to the elastic force of the spring 37, so that the second operation When the pulling force of the child 4 is removed, the third body 32 moves in the direction opposite to arrow A and returns to its original position, and the second switch 44 is opened. On the other hand, the second body 21 is pushed in the direction of arrow C via the second interlocking body 38;
Since the rotation angle of the interlocking body 38 is set smaller than the rotation angle of the first interlocking body 18, the second

is held in the locked state and remains in the "low beam" state described in (a) above.

(e) When setting "Parking" When the third operator 5 is pulled up in the same manner as in (a), the lever part 5a presses the tip of the actuating plate 47 and the ninth
As shown in the figure, the fourth body 45 is moved in the direction of arrow A. As a result, the third movable contact 5
1 connects between the fixed contact pieces 52 and 52 and closes the third switch 53. On the other hand, the third lock mechanism 48
Similarly to the first locking mechanism 24 described in section (a), the bent portion 50a of the spring 50 is engaged with the second engaging portion 49c through the passage _S3 of the engaging portion 49, and the second locking portion 49c is engaged with the second engaging portion 49c. Lock the body 45 of No. 4 in the operating position.

(f) When changing from "parking" to "off" When the third operator 5 is pulled up in the same way as in (a), the fourth body 45 is pushed in the direction of arrow A, so the bent portion 50a of the spring 50 is the spring 50
As described in section (b), the elastic force moves from the second engagement part 49c to the passage _S3 and releases the engagement. 4
The body 45 moves in the opposite direction of arrow A and returns to its original position, and the third switch 53 is opened.

Next, the second, third, and fourth bodies 21, 32,
The state that occurs when one of the bodies 45 is in a locked state and an attempt is made to lock the other body will be explained with reference to FIGS. 4 and 10, taking the first locking mechanism 24 as an example. do. That is, (g) when setting "parking" from the state set to "high beam", when the third operator 5 is pulled up, the fourth body 45 is moved in the direction of arrow A as described in section (e). the fourth body 45 is locked in the operating position, and the third
switch 53 is closed. On the other hand, the end 67a of the third release member 67 pushes the bent portion 26a of the spring 26 at the second engagement portion 25e of the first locking mechanism 24 against the elastic force of the spring 26 in the direction indicated by the arrow D. The bent portion 26a is moved from the second engagement portion 25e to the section ``'' of the passage _S1 as shown by the two-dot chain line, and the engagement is released. As a result, the second body 21 returns to its original position due to the elastic force of the spring 22, and the first switch 31 is opened. Further, the reset protrusion 66 slides on the oblique part 63 of the second release member 61 and moves the second release member 61 toward the arrow H against the elastic force of the spring 64.

The bent portion 37a of the spring 37 of the second locking mechanism 35 is connected to the second engaging portion 36c.
The third body 32 is returned to its original position and the second switch 4 is moved to the passage _S2 to release the engagement.
4 is released.

(h) When setting to "low beam" or "high beam" from the state set to "parking" Pull up the first controller 3 or second controller 4 and point the first or third body 15 or 32 with the arrow Move in direction A. As a result, as shown in FIG.
As a result, the first release member 54 moves in the direction of arrow H against the elastic force of the spring 57 to the position shown by the two-dot chain line, and the first release member 54 slides on the diagonal portion 55 or 56 of the notch 60 . The upper end in FIG. 11 pushes out the bent portion 50a of the spring 50 of the third locking mechanism 48 in the opposite direction of arrow G against its elastic force, and the bent portion 50a is removed from the second engagement portion 49c into the passage. S ₃ to release the engagement and return the fourth body 45 to its original position.

(i) To turn all switches to the "off" state: Pull up the first controller 3. As a result, as described in section (b), if the first switch 31 is on, the second body 21 returns to its original position and the first switch 31 opens. Also, as the first body 15 moves in the direction A, the reset protrusion 5
8 slides on the diagonal portion 55 of the first release member 54 to move the first release member 54 in the direction of arrow H, and when the third switch 53 is on, as described in section (h). In this manner, the third lock mechanism 48 is unlocked, the fourth body 45 is returned to its original position, and the third switch 53 is opened. Further, the reset protrusion 65 slides on the slanted part 62 of the second release member 61, and the second
When the second switch 44 is on, the second release member 61 releases the lock of the second lock mechanism 35 as described in (g). The body 32 of No. 3 is returned to its original position and the second switch 44 is opened. Thereby, by operating the first operator 3, all of the first, second, and third switches 31, 44, and 53 that are in the on state can be opened.

According to the above embodiment, by operating the first operator 3, the first switch 31 can be closed and set to "low beam", and by operating the second operator 4, the first and second switches can be set. "High beam" can be set by closing the switches 31 and 44, and "parking" can be set by closing the third switch 53 by operating the third controller 5. If you operate it again, the first, second, and
Since the third switches 31, 44, and 53 can all be returned to the "off" state, it is possible to eliminate the need for a dedicated "off" operator.
