- the encoder contact case 8 has a through hole 8 through which the pressing member 5 is inserted. 1 is formed in the center. A bottom portion 82 is formed so as to surround the through hole 81 in an annular shape, and the conductive pattern 82a is formed on the annular bottom portion 82.
- the sliding member 7 and the conductor no-turn 82a constitute a rotation detecting means, and the terminal 82b shown in FIG. 1 protrudes from the case side wall to the outside.
- the conductive pattern 82a and the terminal 82b are conductively connected.
- An inner wall 83 extending vertically upward from the bottom 82 is formed around the annular bottom 82.
- the inner wall 83 is set to a height substantially the same as the thickness of the click engagement portion 64, which is the large diameter portion of the rotating member 6, and the rotating member 6 disposed on the annular bottom 82 is rotatably held without play. It is made to do so.
- the encoder contact case 8 has a substantially rectangular shape, and holes 84a to 84d are formed at four corners on the upper surface. Also, on the two opposite sides of the encoder contact case 8, the side surface 153a composed of the feet 151a, 151b and the snap feet 152a of the mounting plate 15 and the side surface 153b composed of the feet 151c, 151d and the snap feet 152b are fitted. Recesses 85b and 85a are formed.
- the two case fixing projections 48a, 48b force formed on the lower surface of the bearing member 4
- Two of the four holes 84a to 84d located on one diagonal line (for example, hole 84a and hole 84d) It is press-fitted into.
- a circular recess 141 in which the movable contacts 13a and 13b are installed is formed on the upper surface of the push contact case 14.
- Fixed contact points 142 and 143 are provided at the central part and the peripheral part of the circular concave part 141.
- Protrusions 145a and 145b are formed at two corners on the upper surface of the push contact case 14.
- the protrusions 145a and 145b are pressed into the two holes 84a and 84b of the encoder contact case 8, and the encoder contact case 8 and the push contact case 14 are positioned and fixed.
- Terminals 147a and 147b are taken out from the side surface 146 of the push contact case 14 to the outside.
- Each terminal 147a, 147b is electrically connected to a fixed contact 142, 143 formed in the circular recess 141 of the push contact case 14.
- the mounting plate 15 has a central portion with a diameter of the cylindrical bearing portion 41 of the bearing member 4.
- the opening 154 is larger and shorter than one side of the case mounting plate 42. From two opposing side surface parts 153a and 153b of the mounting plate 15, legs 151a to 151d and snap legs 152a and 152b whose tip portions are bent inwardly extend downward.
- the mounting plate 15 is engaged with the upper surface of the case mounting plate 42 through the cylindrical bearing 41 of the bearing member 4 in the opening 154, and the encoder contact case 8 and the push contact case 14 are assembled on the rear surface of the bearing member 4.
- the legs 151a to 151d of the side surface portions 153a and 151 are bent to the lower surface side of the push contact case 14 so as to be integrated together. In this way, the backlash between the members can be removed by firmly sandwiching the bearing member 4, the encoder contact case 8 and the push contact case 14 constituting the casing with the mounting plate 15.
- each slider 71 comes into sliding contact with the conductive pattern 82a formed on the bottom surface 82 of the encoder contact case 8, and a detection signal is output from the terminal 82b to be used for rotation detection. .
- the rollers 12a and 12b that have received a constant pressing force from the coil panel 10 move while rolling on the uneven portion 66, so that the protrusion provided on the plate panel is used as the uneven portion.
- a smoother rotation and a larger click feeling can be realized simultaneously, and a clear sense of moderation can be obtained.
- the force In the lick mechanism, if the amount of deformation of the plate panel is increased to obtain a large click feeling, it cannot be used for a long time, but if it has a structure in which the rollers 12a and 12b are pressed by the coil panel 10, it is more durable than the plate panel. Can be greatly improved.
- a cylindrical portion 41b is formed on the inner wall portion of the bearing member 4 so as to pass through the coil panel 10, and the holding member 11 receiving the urging force from the coil panel 10 is supported so as to be movable in the roller pressing direction. Since movement in the rotational direction is restricted, the coil panel 10 is not deformed in a direction other than the expansion / contraction direction, and almost all of the urging force is applied to the rollers 12a and 12b via the holding member 11, so that a constant operation is always performed. A sense is obtained.
- convex portions 112a and 112b projecting radially outward are provided at positions that are different from the portions that hold the rollers 12a and 12b in the holding member 11, that is, positions that face each other across the axis S. Since the guide recesses 44a and 44b for guiding the shaped portions 112a and 112b to be movable in the axis S direction are provided in the bearing member 4, the holding member 11 for holding the rollers 12a and 12b can be moved in the axis S direction smoothly. Good click feeling can be obtained.
- the pair of rollers 12a and 12b are arranged at positions facing each other across the axis S of the operation shaft 3, so that a balanced click operation can be realized.
- the engaging portion 25 provided at one end portion of the inner shaft 2 is inserted by a predetermined distance from the end portion of the opening 6 la of the rotating member 6, and then the axis S in the internal space of the rotating member 6.
- the rotation in both the clockwise and counterclockwise directions is restricted and the movement in the pullback direction is also restricted.
- the coil panel 10 and the two rollers 12a and 12b can be temporarily fixed while being held, and the coil panel 10 and the rollers 12a and 12b are not separated during assembly, so that work efficiency is improved and productivity can be improved.
- rollers 12a and 12b are ones in which the wheels 12c and the roller shaft 12d are integrated, but they may be separated.
- the holding member 11 is provided with the two convex portions 112a and 112b.
- the number is not limited and may be one or three or more.
- two or more sets of force each provided with a pair of the rollers 12a and 12b may be provided.
- the force push switch function that has a push switch function is not necessarily an essential element.
