DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention is shown in FIGS. The switch device of this embodiment is a power window system switch device. The power window system switch device is shown in a top view of FIG.
5 (b), 1 is a housing, 2 is an operation knob for operating a window glass of a driver's seat, 7,
Reference numerals 8 and 9 denote operation knobs for operating window glasses of the passenger seat, the rear left seat, and the rear right seat, respectively, which will be described in detail below.

First, the housing 1 will be described. The housing 1 is a component formed of a synthetic resin, and has a contact mechanism, a control circuit, and the like built therein. Further, the housing 1 has a frame 13 on its outer upper surface, and the operation knob 2 is elastically fitted to shafts 14 and 15 formed on the frame 13.
Thus, the operation knob 2 is supported by the housing 1 so as to be rotatable about the shafts 14 and 15.

The housing 1 has two cylinders 11 and 12 provided therein, and detents 3 and 4 urged by springs 5 and 6 are mounted on each of the cylinders 11 and 12. ing. The detent elements 3, 4 are components for imparting detent to the operation knob 2, and have a cylindrical shape. The cylinders 11 and 12 are arranged in a row in the operation direction of the operation knob 2.

Next, the operation knob 2 will be described. The operation knob 2
Has a moderator 25 on the inner surface. The detent body 25 has a wall surface composed of a first surface 21, a second surface 22, a third surface 23, and a fourth surface 24. Each of the surfaces 21 to 24 is inverted W-shaped in the operating direction of the operation knob 2. When the operation knob 2 is at the neutral position, the first surface 21 and the fourth surface 24 located outside the second surface 22 and the third surface 23, and the cylindrical body 11,
The moderators 3 and 4 are sandwiched between twelve wall surfaces 111 and 121 extending in the axial direction.

FIG. 4 shows this state in an enlarged manner. As can be seen from the figure, when the operation knob 2 is in the neutral position, one of the decelerators 3 is in contact with the first surface 21 of the detent body 25 at the point B, and is in contact with the wall surface 111 of the cylindrical body 11 at the point C. . The other moderator 4 is also connected to the fourth surface 24 of the moderator 25 by E
While contacting at a point, it contacts the wall surface 121 of the cylindrical body 12 at a point D. Therefore, when the operation knob 2 is in the neutral position, even if there are gaps r and s between the detents 3 and 4 and the cylinders 11 and 12 of the housing 1, the detents 3 and 4 are Since it is firmly sandwiched between the wall surfaces 111 and 121 of the bodies 11 and 12, the moderators 3 and 4 do not fluctuate, and therefore the operation knob 2 does not fluctuate in the operation direction.

Next, the operation will be described. The knob structure of the above-described embodiment has a structure in which the moderators 3 and 4 slide or roll on the respective surfaces 21 to 24 of the moderator 25 to give resistance and moderation to the operation knob 2. The operation positions of the neutral position, the manual position, and the automatic position can be determined based on the resistance and the sense of moderation. For example, the operation knob 2 is shown in FIGS.
When operating from the neutral position O shown in FIG. 2 to the manual position M shown in FIG. 2, resistance is given by the springs 5 and 6, but the moderator 3 is on the first surface 21 and the moderator 4 is Since it is above, no sense of moderation occurs.

Next, the operation knob 2 is moved to the automatic position A shown in FIG.
When the moderator 3 is operated, the moderator 3 moves over the vertex P1 at the end of the first surface 21 and the moderator 4 moves over the vertex P2 at the end of the third surface 23. Occur.

The operating force of the operating knob 2 operates a contact structure in the housing 1 via a lever (not shown) provided on the operating knob 2. The control circuit connected to the switch device controls the corresponding window regulator upon receiving the operation signal, and opens and closes the window glass.

[0018]

According to the present invention, there is provided a switch including a housing, an operation knob rotatably supported by the housing, and a detent provided between the operation knob and the housing and providing a detent to the operation knob. In the apparatus, a plurality of cylinders are provided in the housing, and a moderator that is urged by a spring is attached to each of the cylinders, a moderator is provided on the operation knob, and a wall surface of the moderator and the cylinder are provided. Since the moderator is sandwiched between the wall surface extending in the axial direction, even if there is a gap between the moderator and the cylinder of the housing, the operation knob is securely fixed to the housing at the neutral position where the operation knob is not operated. However, there is an effect that the wobble of the operation knob can be eliminated.

Further, since the cylinders are arranged in the operating direction of the operating knob, the width in the direction perpendicular to the operating direction of the operating knob can be reduced.

Further, the detent body has a first surface, a second surface, and a third surface.
Surface and a wall surface composed of a fourth surface, and the respective surfaces are arranged in an inverted W shape in the operating direction of the operation knob, so that each of the neutral position, the manual position, and the automatic position of the switch device of the power window system is provided. There is an effect that resistance and moderation corresponding to the operation position can be given to the operation knob.

Further, the moderator is sandwiched between the first and fourth surfaces of the moderator located outside the second and third surfaces of the moderator and the wall surface of the cylindrical body. There is an effect that the fixing force at the time of fixing the operation knob to the housing at the position is strong.
