【Example】

 An embodiment of the present invention will be described below with reference to the drawings. First, in FIG. 2, a rectangular through hole 3c is formed in the operation lever 3. A shaft body 2 having shafts 2a and 2a is loosely fitted in the through hole 3c, and the shaft body 2 is rotatably supported by an operating lever 3 by a shaft 2b. In this case, the axes of the shafts 2a and 2a and the axis of the shaft 2b are orthogonal to each other.

One shaft 2 a of the shaft body 2 is rotatably supported by a synthetic resin main body case 1, and the other shaft 2 a covers a synthetic resin cover that closes an upper (front) opening of the main body case 1. It is rotatably supported at 7. Therefore, the operating lever 3 rotates integrally with the shaft 2b in the first direction (direction of arrow A in FIG. 1) about the shaft body 2 and, further, in the second direction (centered around the shaft 2b). It also rotates in the direction of arrow B in FIG. In addition, an elongated hole-shaped storage portion 3a is formed at the left end of the operating lever 3, and an engagement element 4 is stored in the storage portion 3a via a compression coil spring 5.

A moderation crest 6 is integrally formed on the main body case 1, and the engagement element 4 is pressed against the moderation crest 6 by the urging force of the compression coil spring 5. As will be described later, this moderation crest 6 engages with the engaging element 4 and restricts the position of the operating lever 3 to the “OFF position”, the “ON position”, the “LO position”, and the “HI position”. As shown in FIG. 5, step portions 6a, 6d, 6e, slopes 6b, 6f and valley portions 6c are provided. In this case, the step portion 6a is inclined so that the protrusion amount becomes smaller toward the right side, and the step portion 6e is inclined so that the protrusion amount becomes smaller toward the left side. 6d is inclined so as to project forward as it goes downward. The slope 6b is inclined so as to project forward as it goes downward and becomes smaller as it goes to the right, and the slope 6f projects forward as it goes downward and has a projection amount as it goes left. It is inclined to be small.

By the way, FIGS. 1 and 2 show a state in which the operation lever 3 is held in the off position. In this state, as shown in FIG. 2, the engaging element 4 is engaged with the stepped portion 6a of the moderation peak 6 and is retained by the retaining portion 7a formed on the cover 7. As a result, the operation lever 3 is restricted from rotating in the opposite arrow B direction. However, in FIG. 1 and FIG. 5, the operation lever 3 is given a turning force in the direction opposite to the arrow A direction due to the inclination of the step portion 6a to the right. Since it is locked by the stopper 1a, rotation in the direction opposite to the arrow A is restricted.

From this state, when the operation lever 3 is operated in the direction of arrow A, the engaging element 4 engages with the valley 6c through the step 6a of the moderation crest 6 and the operation lever 3 is held at the "LO position". R. When the operating lever 3 in the "LO position" is operated in the direction of arrow A, the engaging element 4 engages with the stepped portion 6e via the valley portion 6c of the moderation crest 6. In this state, a turning force in the direction of arrow A is applied to the operation lever 3 by tilting the step 6e to the left. However, the operation lever 3 is held in the "HI position" because it is locked by the upper locking portion 1b of the main body case 1.

A contact holder 8 is integrally provided on the shaft body 2 of the operation lever 3. As shown in FIG. 3, holes 8a, 8a are formed at the tip of the contact holder 8, and a movable contact 9 is vertically movably inserted into the holes 8a, 8a. A compression coil spring 10 is provided between the lower surface of the contact holder 8 and the movable contact 9. The movable contact 9 is retained from the holes 8a, 8a by cutting and raising parts 9a, 9a.

As shown in FIG. 1, the movable contact 9 constitutes a wiper switch 12 for connecting and disconnecting a wiper device (not shown) together with four fixed contacts 11 a to 11 d fixed to the main body case 1. It is a thing. Then, in the state where the operation lever 3 is held in the "off position", the movable contact 9 comes into contact with the fixed contacts 11a and 11b, and the wiper switch 12 is turned off. Further, when the operating lever 3 is rotated to the "HI position" via the "LO position", the movable contact 9 is switched from the contact state with the fixed contacts 11b, 11c to the contact state with the fixed contacts 11c, 11d. . Thereby, the wiper device is configured to switch from the low speed operation state to the high speed operation state.

As shown in FIG. 2, the main body case 1 is provided with a fixed contact point 13 located below the operation lever 3. A movable contact piece 14 made of a leaf spring having a contact portion 14a is provided on the upper side of the fixed contact 13, and the fixed contact 13 and the movable contact piece 14 are used to connect and disconnect a washer device (not shown). The washer switch 15 is configured. Then, in the state where the operation lever 3 is held in the "OFF position", the pressing portion 3b formed on the operation lever 3 does not push down the movable contact piece 14. Therefore, the contact portion 14a of the movable contact 14 is not in contact with the fixed contact 13, and the washer switch 15 is turned off.

A protrusion 16 is integrally formed on the body case 1 below the operating lever 3. As shown in FIG. 4, the protrusion 16 is formed with an inclined surface-shaped guide portion 16a that descends in the direction of the arrow A (to the left), and the operation lever is in the "off position". When 3 is rotated in the direction of arrow B, the contact portion 3c formed in the corner of the operation lever 3 is in contact with the guide portion 16a, and the operation lever 3 is rotated in the direction of arrow B while the arrow 3 is rotated. You will be guided in the A direction.

According to the above-described embodiment, when the operating lever 3 in the “off position” in FIG. 2 is operated in the direction of arrow B, first, the engaging element 4 is pressed against the slope 6b of the moderation crest 6 and the compression coil is pressed. The engagement element 4 retracts as the spring 5 contracts. Next, in FIG. 4, when the contact portion 3c of the operation lever 3 comes into contact with the guide portion 16a, the operation lever 3 is rotated in the direction opposite to the arrow A as it is operated in the arrow B direction. Like Finally, in FIG. 1, the engagement element 4 is held at the “LO position” in a state of being engaged with the trough portion 6c of the moderation crest 6.

Then, as indicated by a chain double-dashed line in FIG. 4, the movable contact piece 14 is pushed down by being pushed by the pushing portion 3b of the operation lever 3. Then, since the contact portion 14a of the movable contact piece 14 contacts the fixed contact 13, the washer switch 15 is turned on and the cleaning liquid is sprayed on the front glass. Moreover, in FIG. 1, since the movable contact 9 comes into contact with the fixed contacts 11b and 11c, the wiper switch 12 is turned on and the windshield is wiped at a low speed.

After that, when the pressing force on the operation lever 3 in the direction of the arrow B is released, the engaging element 4 projects due to the restoring force of the compression coil spring 5 in FIG. Since the turning force in the direction of the arrow B is applied, the operation lever 3 automatically returns to the “off position” of the washer switch 15. Then, the contact portion 14a of the movable contact piece 14 separates from the fixed contact 13, and the washer switch 15 is turned off, but the movable contact 9 remains in contact with the fixed contacts 11b and 11c, so that the low speed of the windshield is reduced. The wiping operation of is continued.

As described above, when the operation lever 3 is operated from the “off position” to turn on the washer switch 15, the wiper switch 12 is automatically turned on. Instead, since it is realized by the inexpensive guide portion 16a integrally formed with the main body case 1, the cost can be reduced as compared with the conventional case.

In the above embodiment, even if the operation lever 3 at the “LO position” or the “HI position” is operated in the arrow B direction, the operation lever 3 moves in the arrow B direction along the moderation crest 6. Moving. Then, it is pushed down by the lower surface of the operating lever 3, and the contact portion 14a of the movable contact piece 14 comes into contact with the fixed contact 13, so that the washer switch 15 is turned on while the wiper device is operating at low speed or high speed.

Further, in the above embodiment, the contact portion 3c of the operation lever 3 that contacts the guide portion 16a is tapered, but it may be horizontal or curved. Further, in the above-described embodiment, the guide portion 16a is provided on the protrusion 16, but, for example, the moderation mountain 6 may be formed with a guide portion which is inclined downward in the direction of the arrow A.
