The lever 22 is provided with a sign 27 indicating an increase or decrease in the intermittent operation time of the front wiper of the automobile.

  On the other hand, as shown in FIGS. 1, 3, and 4, the knob inner body 24b has a convex portion 28 formed on the inner surface thereof. The convex portion 28 protrudes in the radial direction (centripetal direction) of the knob inner body 24b. In addition, a large number of moderation valleys 29 are formed in a semicircular shape on the end surface of one side (in this case, the side opposite to the switch body 21 side) in the axial direction (left and right direction in FIG. 1) of the knob inner body 24b. It is formed by arrangement.

  In contrast, an insulator 30 is disposed inside the knob inner body 24b. The insulator 30 has a main body 30a having a rectangular long plate shape, and has arm portions 30b and 30c projecting upward and downward at both side edges of the main body 30a. The part has a leg part 30d protruding downward. Further, the outer surfaces of the arm portions 30b and 30c and the lower surface of the leg portion 30d are formed in a curved shape that follows the curved surface of the inner peripheral surface of the knob inner body 24b. With this configuration, the arm portions 30b and 30c The entire insulator 30 is inserted and disposed inside the knob inner body 24b while the outer surfaces and the lower surfaces of the leg portions 30d are in sliding contact with the inner peripheral surface of the knob inner body 24b.

  In addition, a plurality of fixed contacts 31 are provided on the upper surface of the main body 30a of the insulator 30 by embedding only the surface of a conductor such as a copper plate, or by printed wiring such as copper foil.

It is loaded in a space 33 surrounded by the inner peripheral surface of 24b. That is, the moving element 32 is shaped to be loaded in the space 33 so that the linear movement in the axial direction of the moving element 32 in the knob inner body 24b can be guided without any shame. It has become.

  A movable contact 34 is mounted on the lower surface of the movable element 32. Accordingly, the movable element 32 is a contact holder that holds the movable contact 34. The movable contact 34 corresponds to the fixed contact 31, and the movable element 34 By moving 32, the contact with the fixed contact 31 is changed, and an output for increasing or decreasing the intermittent operation time of the front wiper of the automobile is generated.

  A groove portion 35 is formed in the upper surface portion, which is the outer surface portion of the mover 32 that forms a mountain shape. The groove 35 is inclined in the axial direction with respect to the rotational direction of the knob inner body 24b (rotary knob 24), and the convex portion 28 of the knob inner body 24b is slidably engaged with the groove 35. .

  A moderation piece 36 is engaged with one of the moderation valleys 29 by being pressed by the spring force of a spring 37. The spring 37 is housed in a housing portion 38 formed inside the lever 22, and the moderation piece 36 projects from the housing portion 38.

  Further, as shown in FIG. 2, a rotary knob 39 different from the rotary knob 24 is rotatably provided at the tip of the lever 22. The rotary knob 39 is for controlling the rear wiper of the automobile. An indicator 40 for this purpose is provided on the outer surface of the lever 22 and an instruction mark 41 is provided on the outer surface of the rotary knob 39. A contact that is switched in accordance with the illustration is provided inside the lever 22.

On the other hand, in the rotation in the counterclockwise direction B in FIG. 1, the convex portion 28 gradually pushes the inclined surface on the right side of the groove portion 35 in FIG. A straight line is moved in the right axial direction Y. As a result, the movable contact 34 held by the movable element 32 changes the contact with the fixed contact 31, and an output is generated to increase or decrease the intermittent operation time of the front wiper of the automobile. Meanwhile, the moderation valley 29 changes the engagement position of the moderation piece 36, and the rotary knob 24 is locked by the engagement of the rotary knob 24 at the position after the rotary operation.

  Therefore, in the case of this configuration, the convex part 28 of the rotary knob 24 and the groove part 35 of the moving element 32 are operation converting means for converting the operation rotation of the rotary knob 24 into the linear movement of the moving element 32, and the convex part thereof 28 is formed on the inner surface portion of the rotary knob 24, and unlike the groove portion 3 formed in the form that penetrates the peripheral wall of the rotary inner body 2 b of the conventional rotary knob 2 in the radial direction, It only protrudes to the inner surface portion, and therefore its formation is easy. Further, since the groove portion 35 formed on the movable element 32 is also formed on the outer surface portion of the movable element 32, it is easy to form and can be formed without requiring a complicated mold. Can be configured cheaply.
