Next, the operation of this embodiment configured as above will be explained.

First, turn the operating lever 4 to the OFF position by rotating it to the maximum in the direction of arrow A, and then turn the operating lever 4 to the OFF position.
When any operating force is released, the operating lever 4 is rotated in the direction of arrow B by the return rotational force of the return spring 19, and the moderation pin 10 is rotated in the direction of arrow B.
is the original return position R where the movable member 3 engages with the boundary between the first inclined portion 14a and the valley portion 14b.
3 (see FIG. 4). In this state, the movable contact 34 closes between the fixed contacts 24 and 25, and the wiper motor 49 is in a stopped state. Next, from this OFF position OFF, operate lever 4.
When rotated approximately 10 degrees in the direction of arrow A to reach the interval position INT, the moderation pin 10 is aligned with the concave portion 1.
5, the movable contact 34 closes between the fixed contacts 25 and 26, and the movable contact 35 closes between the fixed contacts 29 and 30.
In this state, the interval control circuit 51
is activated, and as is well known, the wiper motor 49 is intermittently energized and rotated at a low speed. Operation lever 4
about 10 in the direction of arrow A from the interval position INT
When the moderation pin 10 is rotated once to the low position LO, the moderation pin 10 is opposed to the grooved portion 16, and in this state, the movable contact 34 is moved to the fixed contact 26, 27.
The wiper motor 49 is continuously operated at a low speed so that the gap is closed. Move control lever 4 to low position
Rotate about 10 degrees in the direction of arrow A from LO to the high position
When set to HI, the moderation pin 10 is opposed to the concave portion 17, and in this state, the movable contact 34
closes between the fixed contacts 27 and 28, and the wiper motor 49 is continuously operated at high speed. When the operating lever 4 is swung in the first direction, ie, the arrow A direction and the counter-arrow A direction, the movable member 33 is moved to the switch cover 22 via the engagement groove 41.
The movable contact 3 is guided by the one side portion 22a and the guide rib 22b inside and reciprocated in the directions of arrow C and counter-arrow C, and the movable contact 3
4, 35 and the fixed contacts 23 to 30, the switching state of the wiper switch 38 is changed.

Now, when the operating lever 4 is in the original return R of the off position OFF (see Fig. 4), the operating lever 4 is moved in the first direction, ie, the arrow A, and in the second direction, which is the arrow that intersects with the counter-arrow A direction. B and anti-arrow B
The state of swinging operation in the direction will be explained. That is,
When the operating lever 4 is swung in the direction opposite to the arrow B from the original return position R, the moderation pin 10 slides along the trough 14b and engages with the boundary between the trough 14b and the hill 14c with a sense of moderation. However, as shown in FIG.
Corresponds to 1c. By swinging the operating lever 4 from the original return position R to the first stage operating position Sa, the operating lever 4 presses the push pin 43 and causes it to slide in the direction of arrow D, and the push pin 43 is movable. The contact 45 is pressed to close the space between the movable contact 45 and the fixed contact 46, that is, the washer switch 47 is turned on, and the washer motor 50 is energized and operates to spray the washer fluid onto the windshield of a car, etc. Inject to. Next, when the operating lever 4 is further swung in the opposite direction of arrow B from the first stage operating position Sa, the moderation pin 10 climbs over the hill portion 14c and rides on the second inclined portion 14d, and the operating lever 4 is a second stage operating position Sb that fits into the clamping portion 41b, as shown in FIG. Then, in the process of swinging the operating lever 4 from the first operating position Sa to the second operating position Sb, the operating lever 4 presses the first inclined portion 41c downward. Along with this, the movable member 33 comes to move in the opposite direction of arrow C, and the movable member 33 comes to be located at the auxiliary low position LOa where the movable contact 34 closes between the fixed contacts 24 and 23. In this case, as described above, the first moderation mechanism 18
The groove 14 (see FIG. 5) is formed to be oriented in the front-rear direction, and a second moderation mechanism 20 (see FIG. 3) is formed in the groove 14 in the front-rear direction. Therefore, when the operating lever 4 is rotated in the direction of arrow A by the operator, the concave portion 1
4 and the concave portion 15, and is moved to the interval position INT, that is, in the direction of arrow C.
At other times, the arrow C
Movement in this direction and in the opposite direction of arrow C is restricted. Therefore, the guide groove 41 can be opened by the operation lever 4.
When the first inclined portion 41c of is pressed downward in FIG. Therefore, the movable member 33 moves smoothly in the opposite direction of arrow C. As a result, the wiper motor 49 is rotated at a low speed, and the wiper operates to wipe the windshield etc. at a low speed in the same way as when the operating lever 4 is operated to the low position LO. Further, when the operating lever 4 is located at the second stage operating position Sb, the operating lever 4 is moved to the push pin 43.
The washer switch 47 continues to be pressed and moved in the direction of arrow D, so that the washer switch 47 remains on and the washer liquid continues to be sprayed onto the windshield and the like. After that, the operating lever 4
When the operating force in the opposite direction of arrow B is released,
The operation lever 4 is now rotated in the direction of arrow B by the return rotation force of the return spring 19.
The moderation pin 10 slides down the second slope 14d, climbs over the hill 14c, slides down the valley 14b toward the first slope 14a, and reaches the boundary between the valley 14b and the first slope 14a. Therefore, the operating lever 4 moves from the second stage operating position Sb to the first stage operating position Sa, as shown in FIG.
The engagement groove 41 returns to the original return position R, and corresponds to the second inclined portion 41d of the engagement groove 41. In this state, the pressing force applied to the push pin 43 by the operating lever 4 is released, the movable contact 45 is separated from the fixed contact 46, and the washer switch 4 is released.
7 returns off. As a result, the washer motor 50 is cut off and stops ejecting the washer fluid. Furthermore, even if the operating lever 4 returns to the original return position R, the movable member 33 remains at the auxiliary low position LOa, so the wiper motor 49 continues to rotate at a low speed, and the wiper motor 49 continues to rotate at a low speed. The wiping operation continues. Thereafter, when the operating lever 4 is swung in the direction of arrow B against the spring force of the return spring 19, the moderation pin 10 is moved to the first inclined portion 14c.
As shown in FIG. 10, the operating lever 4 is positioned at the reaction position Sc where it is fitted into the clamping portion 41a. Then, in the process of swinging the operating lever 4 from the original return position R to the reaction position Sc,
Since the operation lever 4 comes to press the second inclined part 41d upward, the movable member 33 comes to move in the direction of arrow C, and the movable member 33 has its movable contact 34 connected to the fixed contact. The wiper motor 49 returns to the off position OFF, which closes the gap between 24 and 25, and the wiper motor 49 stops. Thereafter, when the swing operation force applied to the operating lever 4 in the direction of arrow B is released, the operating lever 4 is returned to the original return position R shown in FIG. will come back.

In addition, the operating lever 4 is in the interval position INT,
In either the low position LO or the high position HI, from the original return position R until it comes into contact with the lower regulating part 42b of the stopper member 42 (first stage operating position)
When the operating lever 4 is rotated in the opposite direction of arrow B, the push pin 43 is slid in the direction of arrow D, and the washer switch 47 is turned on. Then, the washer liquid is sprayed. Since the operating lever 4 is always urged in the direction of the original return position R by the return spring 19, the washer switch 47
The washer switch 47 is turned on only while it is rotated and held in the opposite direction of arrow B, and when the operating lever 4 releases its holding force and returns to its original return position R, the washer switch 47 is turned on.
returns off.

According to this embodiment, the following effects can be obtained. That is, when the operating lever 4, that is, the movable member 33 is in the off position of the wiper switch 38, the operating lever 4 is
When a swing operation is performed from the original return position R to the first stage operating position Sa, the washer switch 47 is turned on, and when the swing operation is performed from the first stage operating position Sa to the second stage operating position Sb, the washer switch 47 is turned on. While keeping the washer switch 47 in the on state, the movable member 33 is moved to the auxiliary low position LOa of the wiper switch 38 to switch the wiper switch 38 to a low speed wiper wiping operation selection state, and then the second stage When returning from the operating position Sb to the first stage operating position Sa to the original return position R, the washer switch 47 is turned off and then from the original return position R to the first stage operating position Sa in the opposite direction. When the swing operation is performed to the reaction position Sc, the movable member 33
Since the wiper switch 38 is returned to the off position OFF and the wiper switch 38 is returned to the off state of the wiper switching operation, the washer liquid injection operation, both the washer liquid injection and low-speed wiper wiping operations, the washer liquid injection stop, and Low-speed wiping operation of the wiper,
The four states of low-speed wiping stop of the wiper can be realized by reciprocating the operation lever 4 in one direction in the direction of arrow B and in the opposite direction of arrow B. Therefore, the operability is excellent, and It is possible to reliably avoid a situation where the jetting operation of the washer liquid continues even though the wiping operation of the wiper is stopped and the washer liquid remains on the windshield etc. without being wiped off. Moreover, even when the operating force on the operating lever 4 in the opposite direction of the arrow B is released and the operating lever 4 is returned from the second stage operating position Sb to the original return position R, the movable member 4
3 remains in the auxiliary low position LOa and the wiper continues the low-speed wiping operation.
Thereafter, the washer fluid sprayed onto the windshield etc. can be reliably wiped off without any operation of the operating lever 4, making it extremely convenient to use. That is, if the wiping operation of the wiper is also stopped immediately when the operation lever 4 is returned to the original return position R, the washer liquid may not be wiped off and remain on the windshield, etc., and the operation lever 4 This is because it is necessary to operate the wiper again. Moreover, the arrow A on the operating lever 4
The movable member 33 is reciprocated based on the swinging operation in the opposite direction of arrow A to perform the wiper switching operation of the wiper switch 38.
Since it can be realized with a simple structure of providing the first and second inclined portions 41c and 41d in the engagement groove 41, the overall size and price will not increase.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but can of course be implemented with appropriate modifications within the scope of the invention.

As explained above, the present invention has the first part of the operating member.
First and second clamping portions and first and second slopes are provided in the engagement groove that engages with the operating member of the movable member that reciprocates in response to the swing in the direction of the movable member and causes the wiper switch to perform the wiper switching operation. the operating member is guided in a second direction intersecting the first direction in this engagement groove by a moderation mechanism, and the operating member is swung in one direction. This system is designed to sequentially switch between the washer liquid injection operation, the washer liquid injection and wiper wiping operation, the washer liquid injection stop and wiper wiping operation, and the wiper wiping stop. It is excellent and has the practical effect of being able to reliably wipe away the washer liquid.
