Next, the effects of the above configuration will be explained in Figures 9 to 12.
This will be explained with reference to the figures.

(a) When setting "LOW" When the first operator 3 is rotated to the position shown by the two-dot chain line in FIG. 3, the lever part 3a presses the tip of the actuating plate 15 and As shown in , the first body 13 is moved in the direction of arrow A, and the actuating protrusion 18 presses the first arm portion 16a of the first interlocking body 16 to rotate the first interlocking body 16 in the direction of arrow B. make it move. As a result, the second arm portion 16b is connected to the second body 1.
9, the second body 19 is moved in the opposite direction of arrow A to the operating position, and as shown in FIG.
40 is opened and contact pieces 41-42 are closed.

On the other hand, in the first lock mechanism 23, as shown in FIG.
Passing through the section ``'' of the groove 24b, the section ``''
Then, at a position slightly returned in the direction of arrow A, the second body 19 is engaged with the second engaging portion 24d to lock the second body 19 in this operating position. When the rotational force of the first operator 3 is removed, the first operator 3 is pushed by the spring 6 and the ball 7 and returns to the original position shown by the solid line in FIG. The elastic force returns the body 13 to its original position, and the operating protrusion 18 of the body 13 pushes up the third arm 16c of the first interlocking body 16 to return the first interlocking body 16 to its original position (see FIG. 10). ). As a result, between the positive electrode 52 of the battery, the fixed contact piece 41-42, and the fixed contact piece 4
From between 4 and 45 to the low speed terminal 5 of the wiper motor 50
A circuit is formed that reaches the arm 51 via the arm terminal 50c and the wiper motor 50, and the wiper motor 50 rotates at a low speed.

(b) To change from "low" to "off" Rotate the first controller 3 in the same way as in (a).
Through the same process as in (a), the second arm portion 16b of the first interlocking body 16 pushes the second body 19 in the opposite direction of arrow A, so that the bent portion 25a of the spring 25
is moved in the direction of arrow C by the elastic force of the spring 25, as shown in FIG.
Since the second body 19 moves in the direction of arrow A by the elastic force of the spring 20, except for the rotational force of the first operator 3, the second body 19 moves in the direction of arrow A. is returned to the off state,
Further, the bent portion 25a of the spring 25 is the groove portion 24b.
The first engagement portion 24c passes through the divisions “” and “”.
and return to the original position.

(c) When setting to "high" When the second operator 4 is rotated to the position shown by the two-dot chain line in FIG. 3, the lever part 4a presses the tip of the actuation plate 28 and 26 in the direction of the arrow A as shown in FIG. 11, the spring 34 of the second locking mechanism 32 has its bent portion 34a in the area of the passage S, as shown in FIG.
The third body 26
lock in the operating position. On the other hand, the third body 2
The operating protrusion 31 of No. 6 pushes down the first arm portion 29a of the second interlocking body 29 and moves the second interlocking body 29 in the direction of arrow D.
direction, the second arm portion 29b pushes up the rib portion 19a of the second body 19, and the first locking mechanism 23 pushes up the second body 1 in the same manner as in (a) above.
9 in the operating position. Therefore, except for the rotational force of the second operator 4, the second operator 4 is returned to its original position in the same way as in (b) above, and the second and third bodies 19 and 26 and the second interlocking The body 29 remains in place. As a result, the fixed contact piece 41-
42 and the fixed contact pieces 46-47 are closed, the high-speed terminal 50a and arm terminal 50c of the wiper motor 50 are connected between the positive electrode 52 of the battery and the arm 51, and the wiper motor 50 rotates at high speed.

(d) When setting from "High" to "Low" When the second operator 4 is rotated in the same manner as in (c), the lever part 4a of the second operator 4 is set to the third position which is in the operating position. The upper end of the actuating plate 28 of the body 26 is pushed in a little further. As a result, the third body 26 is further pushed in the direction of the arrow A, and the bent portion 34a of the spring 34 shown in FIG. Second
from the engaging portion 33d of the passage S to the area ``'' of the passage S to release the engagement. If the rotational force of the second operator 4 is removed here, the second operator 4
returns to its original position, and the third body 26 returns in the opposite direction of arrow A due to the elastic force of the spring 27, switching to a state in which the fixed contact pieces 44-45 are closed. In this case, the movement of the third body 26 also causes the second interlocking body 29 to rotate in the direction of arrow D via the actuating protrusion 31, but this rotation causes the second arm portion 29b to move to the second The amount of displacement that pushes up the body 19 in the opposite direction of arrow A is when the position of pin 30 is pin 1.
Since it is located below 7, it becomes smaller by that amount, and does not increase in size until the bent portion 25a of the spring 25 disengages from the second engaging portion 24d, and as it is, the second engaging portion at the lower part of the convex portion 24a. 24d, and therefore, the second body 19 remains in the locked state and is in the "low" state similar to (a) above.

(e) To change from "high" to "off" Rotate the first operator 3 in the same way as in b. As a result, the second body 19 is returned to its original position through the process described in (b) above. When the first body 13 moves in the direction of arrow A, the reset protrusion 37 releases the release member 35.
The release member 35 is slid in the direction of arrow F by coming into contact with the oblique portion 36 on the first body 13 side. As a result, the lower end of the release member 35 in FIG. 2 pushes out the bent portion 34a of the spring 34 in the direction of arrow F, as shown by the two-dot chain line in FIGS. 6 and 12. The third body 26 moves against the elastic force of the spring 27 from the second engagement portion 33d along the protrusion 33a to the area of the passage S and releases the engagement. The force causes it to move in the opposite direction of arrow A and return to its original position. That is, when the first operator 3 is operated, the first and second lock mechanisms 23 and 32, which are in the locked state, can be simultaneously brought into the unlocked state.

According to the above embodiment, by operating the first operator 3, it is possible to set it to "low", and by operating the second operator 4, it is possible to set it to "high",
In addition, by operating the first controller 3 again, all of the set states of "low" and "high" can be returned to the "off" state, eliminating the need for a dedicated "off" controller. be able to.

Note that the present invention is not limited to the above-mentioned embodiment, and for example, the spring 6, the ball 7, and the spring 14 are omitted, respectively, and the rotation of the first and second operators 3 and 4 is used instead. center pin 2
A is equipped with a torsion spring that biases each of these in the direction shown by the arrow X in FIG. When the body 13 or 26 is in the operating position moved in the direction of the arrow A, the elastic force of the torsion spring causes the first and second operating elements 3 or 4 to remain unchanged even after the operation is completed, as indicated by the two-dot chain line in FIG. When the first body 13 returns to its original position via the second body 19 and the first interlocking body 16 due to the elastic force of the spring 20, Only when the third body 26 is returned to its original position by the elastic force of the spring 27, the first and second operators 3 and 4 are returned to the positions indicated by solid lines in FIG. 3, respectively. It may be rotated. In this case, in addition to the effects shown in the above-described embodiments, there is an effect that the switch in the on state can be displayed by the first or second operator 3 or 4.
