The supported portion 72A is in contact with the rotor-side support surface 63 of the rotor 60 from below.

The operated member 72 is urged upward by the urging force of a first buffer spring 90, which will be described later, so that the operated member 72 (operating portion 70) is held at a neutral position. Thereby, the operated member 72 (the operation portion 70) is supported by the rotor 60 from above so as to be swingable. By applying an operating force in the first direction or the second direction to the operated member 72, the operated member 72 (the operating portion 70) shifts from the neutral position to the swing position (the position shown in FIG. 7). It is configured to be swung (FIG. 7 illustrates a state in which the operated member 72 (the operating portion 70) is swung from the neutral position to one side in the second direction). Further, when a downward pressing force is applied to the operated member 72, the operated member 72 (operating portion 70) is displaced downward from the neutral position at the pressing position (indicated by the chain double-dashed line in FIG. 6). position).

Four engagement projections 72B corresponding to the engagement grooves 64 of the rotor 60 are formed on the outer peripheral portion of the lower end portion of the supported portion 72A. It is formed in a substantially columnar shape with an axial direction. The engagement protrusion 72B is inserted into the engagement groove 64 of the rotor 60 so as to be relatively movable in the longitudinal direction of the engagement groove 64 and to be engaged in the circumferential direction of the operated member 72 .

When the operating portion 70 swings, the lower surface of the lower shaft portion 76B slides on the upper surface of the push member 50. As shown in FIG.

The guide shaft portion 76C is set to have a diameter smaller than that of the lower shaft portion 76B. The guide shaft portion 76C is inserted into the guide groove 52 of the push member 50 so as to be relatively movable. Specifically, when the operation portion 70 is swung in the first direction, the guide shaft portion 76C is guided by the first guide groove portion 52A, and when the operation portion 70 is swung in the second direction, the second guide shaft portion 76C is guided. The guide shaft portion 76C is guided by the groove portion 52B.

The second buffer spring 78 is configured as a compression coil spring. The second buffer spring 78 is arranged inside the operated member 72 and above the operating shaft 76 . Specifically, the upper end of the second buffer spring 78 is locked to the upper wall of the operated member 72, and the lower end of the second buffer spring 78 is locked to the stepped portion 76D of the operating shaft 76, thereby A 2-buffer spring 78 biases the operating shaft 76 downward. As a result, the lower surface of the upper shaft portion 76A of the operating shaft 76 is in contact with the upper surface of the spring bearing member 74. As shown in FIG.

(Switch operating member 80)
As shown in FIGS. 2 and 4, the switch operating member 80 is made of a resin material. The switch actuating member 80 is formed in a substantially cross-shaped plate having a plate thickness direction in the vertical direction, and is arranged inside the rotor 60 and above the base support portion 43 of the base member 40 . The switch actuating member 80 includes a body portion 81 forming a central portion of the switch actuating member 80, and four arm portions 82 extending from the body portion 81 in both first and second directions. , is composed of

The main body portion 81 is formed in a substantially bottomed cylindrical shape that is open downward, and the side wall of the main body portion 81 is inclined radially outward toward the lower side. A supported convex portion 81A is formed as a supported portion at the center of the lower surface of the upper wall of the main body portion 81 . The supported convex portion 81A is formed in a substantially hemispherical shape that protrudes downward. Further, an insertion hole 81B is vertically formed through the central portion of the body portion 81, and the lower shaft portion 76B of the operating shaft 76 is inserted into the insertion hole 81B so as to be relatively movable in the axial direction. ing. In addition, when the switch actuating member 80 is connected to the operating shaft 76, the supported convex portion 81A is in contact with the base-side support surface 43A of the base member 40 from above due to the biasing force of the first buffer spring 90, which will be described later. . Thereby, the switch operating member 80 is connected to the operating shaft 76 so as to be able to swing integrally with the operating shaft 76 . When the operating portion 70 swings, the supported convex portion 81A slides on the base-side supporting surface 43A.

The arm portion 82 extends radially outward of the body portion 81 from the lower end portion of the side wall of the body portion 81 . The arm portion 82 is configured to be elastically deformable in the vertical direction. A distal end portion of the arm portion 82 is configured as a switch actuating portion 82A. The switch actuating portion 82A is bent downward and arranged adjacent to the upper side of the tactile switch 22. As shown in FIG.

(Regarding the first buffer spring 90)
As shown in FIG. 2, the first buffer spring 90 is configured as a compression coil spring, mounted on the operating shaft 76, and positioned between the spring receiving member 74 and the switch operating member 80. As shown in FIG. Specifically, the upper end of the first buffer spring 90 is engaged with the spring receiving member 74, the lower end of the first buffer spring 90 is engaged with the switch operating member 80 via a washer, and the first buffer spring 90 is engaged with the switch operating member 80. A buffer spring 90 biases the spring receiving member 74 upward and biases the switch operating member 80 downward. As a result, the supported convex portion 81A of the switch operating member 80 is supported by the base side support surface 43A of the base member 40 from below, and the supported portion 72A of the operated member 72 is supported by the rotor side support surface of the rotor 60. 63 is supported from above.

As shown in FIG. 7, when the operated member 72 is operated to swing, the operated member 72 and the operating shaft 76 swing together with the switch operating member 80 to the swinging position. The biasing force of the first buffer spring 90 is set so that the actuating portion 82A presses the vertically opposed tactile switch 22 to activate the tactile switch 22 . In addition, although the details will be described later, when an operation force for further swinging the operated member 72 in the swinging position is input to the operated member 72, the main body portion 81 of the switch operating member 80 acts as the first buffer spring. The biasing force of the first buffer spring 90 is set so that the biasing force of the first buffer spring 90 is resisted and the operating shaft 76 moves toward the upper end side. Also, at this time, the arm portion 82 of the switch operating member 80 is configured to bend and deform upward.

When the operated member 72 is pressed downward, the operated member 72 and the operating shaft 76 move downward relative to the switch operating member 80 against the biasing force of the first buffer spring 90 . Then, the push switch 21 is pushed by the push member 50 . As a result, the position of the switch operating member 80 does not change when the operated member 72 is pushed, so that the operation of the tactile switch 22 by the switch operating member 80 is prevented. On the other hand, as shown in FIG. 6, when an operation force is input to the operated member 72 to further lower the operated member 72 in the pressing position, the second buffer spring 78 deforms and the operated member 72 The biasing force of the second buffer spring 78 is set so that the is displaced downward relative to the operation shaft 76 .

(Action and effect)
Next, the operation and effects of this embodiment will be described.

In the rotating operation of the operating device 10 configured as described above, the operator rotates the operated member 72 around the axis AL. This causes the operated member 72 and the rotor 60 to rotate about the axis AL. Therefore, the state of the optical sensor 23 is switched by the lower end portion of the rotor 60 to a state in which the light traveling from the light-emitting portion to the light-receiving portion is blocked or passes through. Thereby, the rotational position of the operated member 72 is detected by the optical sensor 23 .

Further, in the pressing operation of the operating device 10, the operator presses the operated member 72 downward. As a result, the first buffer spring 90 is compressed and deformed, and the operated member 72 and the operating shaft 76 are displaced downward relative to the rotor 60 and the switch operating member 80 . Therefore, the push member 50 is pushed downward by the operating shaft 76 and displaced downward, and pushes the push switch 21 . Thus, the push switch 21 detects the pressing operation of the operating device 10 .

Further, in the swinging operation of the operating device 10, the operator presses the operated member 72 in the first direction or the second direction. As a result, the operating portion 70 swings in the pressed direction. For example, when a pressing force (operating force) toward one side in the second direction is input to the operated member 72, as shown in FIG. The operated member 72, the operating shaft 76, and the switch operating member 80 integrally swing about the swing center point CP toward one side in the second direction. At this time, the supported convex portion 81A of the switch actuating member 80 is displaced to the other side in the second direction and slides on the base-side support surface 43A of the base member 40 . Further, at this time, the switch operating portion 82A of the arm portion 82 on the one side in the second direction presses the tactile switch 22 from above. Therefore, the swing operation of the operating device 10 is detected by the tactile switch 22 .

As described above, in the operating device 10, the rotor-side support surface 63 of the rotor 60 supports the operated member 72 of the operating portion 70 from above so as to be swingable. Further, the switch operating member 80 is provided on the lower shaft portion 76B of the operating shaft 76 of the operating portion 70 so as to be relatively movable in the axial direction. The supported convex portion 81A is supported from below. Further, the first buffer spring 90 biases the switch operating member 80 downward and biases the operated member 72 of the operating portion 70 upward. Thus, when the operating portion 70 swings, the switch operating member 80 swings integrally with the operating portion 70, and the supported convex portion 81A slides on the base-side support surface 43A.

Here, the switch actuating member 80 has a switch actuating portion 82A that presses the tactile switch 22 when the operating portion 70 is operated to swing. Therefore, for example, the tactile switch 22 can be operated without separately providing a member for operating the tactile switch 22 in conjunction with the rocking motion of the operation unit 70 as described in the background art. That is, the tactile switch 22 can be directly operated by the switch operating member 80 that swings integrally with the operating portion 70 . Thereby, in the operating device 10 , an increase in the number of parts can be suppressed, and the cost of the operating device 10 can be reduced.

Also, the base support portion 43 of the base member 40 is formed in a substantially cylindrical shape, and the base side support surface 43A constituting the upper opening edge of the base support portion 43 corresponds to the diameter of the operation shaft 76 (the base support portion 43). It is configured as an inclined surface that is inclined upward toward the direction outside. Therefore, the operating portion 70 in the swing position can be satisfactorily returned to the neutral position by the urging force of the first buffer spring 90 and the base-side support surface 43A configured as an inclined surface.

The switch actuating member 80 includes a body portion 81 having a supported convex portion 81A and an arm portion 82 extending from the body portion 81 radially outward of the operating shaft 76 . The tactile switch 22 is arranged below the switch actuation portion 82A of the arm portion 82. As shown in FIG. Thereby, the protection performance of the tactile switch 22 can be improved.

That is, as shown in FIG. 7, when an operation force is input to the operated member 72 to further swing the operated member 72 in the swinging position toward one side in the second direction, the switch operating member 80 The switch actuating portion 82A on the one side in the second direction swings toward the one side in the second direction (see arrow a in FIG. 7). At this time, the supported convex portion 81A of the switch operating member 80 slides on the base-side supporting surface 43A, and the body portion 81 of the switch operating member 80 resists the biasing force of the first buffer spring 90. It is displaced to the upper end side of the operating shaft 76 (see arrow b in FIG. 7). As a result, since the operating force input to the operated member 72 is absorbed by the compression deformation of the first buffer spring 90, it is possible to prevent an excessive pressing force from being input to the tactile switch 22. FIG. Therefore, since the arm portion 82 extending radially outward of the operating shaft 76 from the supported convex portion 81A of the main body portion 81 is integrally formed, when an excessive operating force is applied to the operated member 72, However, it is possible to avoid the operation load from the switch actuating portion 82A continuing to be applied to the contacts. 22 can be improved.

Also, the arm portion 82 of the switch operating member 80 is configured to be elastically deformable in the vertical direction. Specifically, when an operation force for further swinging the operated member 72 in the swinging position is input to the operated member 72, the arm portion 82 is bent upward. As a result, the elastic deformation of the arm portion 82 absorbs the operating force input to the operated member 72 , thereby further suppressing input of an excessive pressing force to the tactile switch 22 . Therefore, the protection performance of the tactile switch 22 can be further improved.

Further, the base member 40 has a guide rib 44, and the arm portion 82 of the switch operating member 80 is guided by the guide rib 44 when the operating portion 70 is swung. Therefore, while the guide rib 44 restrains the relative rotation of the switch actuating member 80 with respect to the operating shaft 76 , the tactile switch 22 can be favorably pressed by the switch actuating member 80 when the operating portion 70 swings.

In addition, in the operating portion 70 , the operated member 72 is provided on the upper end portion of the operating shaft 76 so as to be relatively movable, and the second buffer spring 78 urges the operating shaft 76 downward, is urged upward. Furthermore, a push member 50 is provided below the operating shaft 76 , and a push switch 21 operated by the push member 50 is provided below the push member 50 . As a result, the push switch 21 can be operated by pressing the operated member 72 downward. Also, at this time, the first buffer spring 90 is compressed and deformed so that the non-operating state of the switch operating member 80 can be maintained. That is, the non-operating state of the tactile switch 22 can be maintained. Therefore, the operating device 10 can also be configured as a pressing operating device.

Moreover, when an operation force is input to the operated member 72 to further lower the operated member 72 in the pressing position, the second buffer spring 78 is deformed and the operated member 72 moves downward with respect to the operating shaft 76 . relative displacement to the side. As a result, the pressing force applied to the operated member 72 is absorbed by the compressive deformation of the second buffer spring 78, so that application of an excessive pressing force to the push switch 21 can be suppressed. Therefore, protection performance for the push switch 21 can be improved.

Further, the push member 50 is connected to the base member 40 so as to be relatively movable in the vertical direction and relatively non-rotatable about the axis AL. Specifically, the push member 50 is inserted into the base support portion 43 of the base member 40 from below, and the engagement projection 51 of the push member 50 is inserted into the engagement groove portion 43B of the base member 40 . Further, a guide groove 52 is formed in the push member 50, and the guide shaft portion 76C of the operation shaft 76 is inserted into the guide groove 52 to guide the swinging operation of the operation portion 70 by the guide groove 52. . As a result, the push member 50 for pressing the push switch 21 can be used to guide the swinging movement of the operation shaft 76 (the operation portion 70).

The supported portion 72A of the operated member 72 in the operating portion 70 is swingably supported by the rotor-side support surface 63 of the rotor 60, and the rotor 60 is rotatably supported by the case 30. It is configured to be rotatable integrally with the operated member 72 . Therefore, the operating device 10 can also be configured as a rotary operating device.
