- the guided shaft 164 extends from the rear end of the inner shaft 64 to a position behind the rear end of the outer wall 63 along its central axis (same as the central axis c of the coil spring 51).
- the guided shaft 164 has an outer diameter smaller than the outer diameter of the inner shaft 64.
- the guided shaft 164 has an outer diameter of ⁇ 3.8 mm, is coaxial with the inner shaft 64 and extends straight rearward, and has a circular cross-sectional shape orthogonal to the central axis.
- the positioning wall 55 is provided with a guide hole into which the guided shaft 164 can enter, and this guide hole has an outer periphery of the guided shaft 164 so that the guided shaft 164 moves along the central axis c.
- the inner peripheral surface 55a is in sliding contact with the surface 164a.
- the holding portion 52 is formed so that the guide surface 53 extends in the vertical direction.
- the present invention is not limited to this, and the holding portion 52 is formed so that the guide surface extends in the horizontal direction or the inclined direction. May be.
- the dial type switch according to the present invention is a dial type switch for rotating the dial knob, and is rotated by the rotating operation of the dial knob, passing through the center of rotation and orthogonal to the rotating direction.
- a rotating part having an uneven circumferential surface in which unevenness entering and exiting in the radial direction is alternately repeated along the rotational direction, a plunger that can contact the uneven surface, and the diameter so as to contact the uneven surface
- a plunger holding portion that holds the plunger so as to be reciprocally movable along a direction, and a compression coil spring that urges the plunger toward the concavo-convex circumferential surface, and the plunger holding portion includes the plunger A guide surface that extends along the movement path of the outer periphery and surrounds the plunger from the outside with the movement path as a center.
- a receiving portion that contacts one end of the compression coil spring and receives the biasing force, an outer peripheral surface that extends in the direction of the movement path of the plunger and is close to the guide surface, and an inner peripheral surface that has an inner diameter larger than the outer diameter of the compression coil spring
- An outer wall having an outer diameter that extends in the direction of the movement path inside the outer wall and has a rear end at a position in front of the rear end of the outer wall and on which the compression coil spring can be mounted.
- the compression coil spring is mounted on the outer side of the inner shaft and is elastically deformed in the direction of the central axis of the compression coil spring, and is arranged on the plunger holding portion so that its elastic force
- the plunger is pressed against the concave / convex circumferential surface by the difference between the maximum outer diameter of the inner shaft and the inner diameter of the compression coil spring, and the difference between the minimum inner diameter of the inner peripheral surface of the outer wall and the outer diameter of the compression coil spring. Smaller than the difference between the.
- the contact length in the movement path direction between the outer peripheral surface of the outer wall and the guide surface of the plunger holding portion is ensured to effectively regulate the inclination of the plunger.
- the posture of the spring is stabilized to suppress distortion during compression, and the inner shaft is made shorter than the outer wall, so that the compression coil spring is equal to the axial length difference. You can earn an effective length.
- the storage space for the compression coil spring on the rear side of the plunger is shortened compared to the plunger that abuts the compression coil spring on the rear end. Accordingly, even if the contact length in the movement direction between the outer peripheral surface of the outer wall and the guide surface is ensured, the length of the plunger holding portion in the axial length direction is reduced to reduce the size. be able to.
- the inner shaft has a maximum outer diameter such that a difference from the inner diameter of the compression coil spring is zero. According to this configuration, it is possible to facilitate the assembly work of the plunger and the compression coil spring to the plunger holding portion. Specifically, in the assembly operation of the plunger and the compression coil spring to the plunger holding portion, when the compression coil spring is held on the inner shaft from the inner side, the difference between the inner diameter of the compression coil spring and the maximum outer diameter of the inner shaft is zero. Therefore, it is difficult for the compression coil spring to come off from the inner shaft. As a result, the assembling work is facilitated as compared with the case where the plunger and the compression coil spring are assembled to the plunger holding portion in a separated state.
- the plunger extends from the rear end of the inner shaft along the central axis to a position behind the rear end of the outer wall and has an outer diameter smaller than the outer diameter of the inner shaft.
- the plunger holding portion further includes a positioning portion that positions the other end of the compression coil spring at a position rearward of the plunger, and the guided shaft can enter the positioning portion.
- a guide hole is provided, and the guide hole has an inner peripheral surface that is in sliding contact with the outer peripheral surface of the guided shaft so that the guided shaft moves along the central axis. According to this configuration, the guided shaft slides in contact with the inner peripheral surface of the guide hole of the positioning portion and is guided along the central axis direction (movement path direction), so that the plunger reciprocates more smoothly.
- the guide surface of the plunger holding part extends in the vertical direction. According to this configuration, since the gravity acts on the plunger in the moving direction, that is, the direction along the guide surface, the frictional force acting between the guide surface and the plunger is hardly affected by the gravity. As a result, a highly uniform click feeling can be obtained regardless of the turning direction of the dial knob.
- the dial type switch according to the present invention is useful for a dial type switch used for the operation of an electronic device or the like provided in a vehicle or the like, and is suitable for improving the click feeling uniformity in the turning operation of the dial knob. Yes.
