(Structure of click feeling imparting mechanism 100.)
Fig. 1 is an exploded view of a click feeling imparting mechanism 100 according to an embodiment. Fig. 2 is a perspective view showing a structure of the bottom surface side of the operation member 120 provided in the click feeling providing mechanism 100 according to the embodiment. Fig. 3 is a perspective view showing the click feeling providing mechanism 100 (with the cover plate 140 removed) according to the embodiment. Fig. 4 is a plan view showing the click feeling providing mechanism 100 (with the cover plate 140 removed) according to the embodiment. Fig. 5 is a perspective view showing the click feeling imparting mechanism 100 (in a state where the cover plate 140 is attached) according to the embodiment. Fig. 6 is a sectional view a-a of the click feeling imparting mechanism 100 shown in fig. 4. In the following description, the Z-axis direction is referred to as the vertical direction in the drawings for convenience.
The click feeling providing mechanism 100 shown in fig. 1 to 6 is a device capable of performing a rotating operation and a pressing operation by the operation member 120. The click feeling providing mechanism 100 is mounted on the surface of a touch panel mounted on a vehicle, for example. Thus, the user can perform the rotation operation or the pressing operation with respect to the touch panel via the operation member 120 instead of directly performing the rotation operation or the pressing operation of the touch panel using a finger. In particular, the click feeling providing mechanism 100 is configured to be thin, and can provide a click feeling to the user in response to the rotation operation and the pressing operation, respectively.
As shown in fig. 1, the click feeling providing mechanism 100 includes a housing 110, an operation member 120, a first leaf spring 131, a second leaf spring 133, a slide member 132, and a cover plate 140.
The housing 110 is a member to which other components (the operation member 120, the first leaf spring 131, the second leaf spring 133, the slide member 132, and the cover plate 140) are assembled. The housing 110 is made of a relatively hard resin material, for example. The housing 110 has a body portion 111 and a shaft portion 112.
The body 111 is a substantially thin cylindrical portion having an upper opening. A first plate spring 131, a second plate spring 133, and a slide member 132 are assembled to a peripheral wall portion of the main body 111. Four holding portions 111B, which are cut out to hold the first leaf spring 131 and the second leaf spring 133, are formed on the peripheral wall of the main body 111 at 90 ° intervals on the same circumference. The upper portion of each holding portion 111B is opened so that the first leaf spring 131 and the second leaf spring 133 can be inserted from above.
The shaft portion 112 is a cylindrical portion (i.e., has a hollow structure) extending upward (in the positive direction of the Z axis in the drawing) from the central portion of the inner bottom surface of the body portion 111. The shaft portion 112 is a portion that is inserted into the inner cylindrical portion 121 of the operation member 120 to pivotally support the operation member 120 so as to be capable of rotating and pressing.
The operation member 120 is a cylindrical (i.e., having a hollow structure) member that can perform a rotating operation and a pressing operation. The operation member 120 is made of, for example, a relatively hard resin material. As shown in fig. 3 to 5, the operating member 120 is attached to the shaft portion 112 of the housing 110 such that the shaft portion 112 of the housing 110 penetrates the inner cylindrical portion 121. Thus, the operation member 120 can be rotated in the first direction (the direction of arrow a in fig. 5) and the second direction (the direction of arrow B in fig. 5) with the shaft portion 112 as a rotation axis, and can be pushed downward (the direction of arrow C in fig. 5) along the axial direction (the direction of z axis in the drawing) of the shaft portion 112. The inner diameter of the inner cylindrical portion 121 is slightly larger than the outer shape of the shaft portion 112 so that the operation member 120 can smoothly operate.
As shown in fig. 1 and 2, a plurality of first cam portions 122 protruding outward (outward in the radial direction of the operation member 120) and in the horizontal direction are provided along the lower peripheral edge portion of the operation member 120. The plurality of first cam portions 122 have a curved convex shape provided for giving a click feeling to a rotational operation by the operation member 120.
As shown in fig. 2, a second cam portion 123 protruding outward (outward in the radial direction of the operation member 120 with respect to the rotation axis) and obliquely downward is formed continuously along the peripheral portion on the back side of the plurality of first cam portions 122 formed along the peripheral portion on the lower side of the operation member 120. The second cam portion 123 has a curved convex shape in cross section, and the second cam portion 123 is provided for converting the movement of the operation member 120 in the up-down direction into a sliding motion of the slide member 132 in the radial direction (radial direction of the operation member 120 with respect to the rotation axis), and gives a click feeling to the pressing operation by the operation member 120.
The first plate spring 131 is an example of the "first click feeling imparting means". The first plate spring 131 is a member having spring characteristics, which is formed by processing a metal thin plate-like material. The first plate spring 131 is bent to form a convex portion 131A. As shown in fig. 3 and 4, the first plate spring 131 is assembled at a predetermined assembly position of the main body 111 of the housing 110 such that the convex portion 131A faces the first cam portion 122 formed at the peripheral edge portion of the operation member 120 (i.e., such that the convex portion faces inward in the radial direction of the operation member 120 with respect to the rotation axis). Thus, when the operation member 120 is rotationally operated, the convex portion 131A of the first plate spring 131 abuts against the first cam portion 122 formed in the peripheral edge portion of the operation member 120, and the first plate spring 131 presses the first cam portion 122 via the convex portion 131A, thereby providing a click feeling to the rotational operation by the operation member 120.
The slide member 132 is an example of the "second click feeling imparting means". The sliding member 132 is made of, for example, a relatively hard resin material. The slide member 132 is a member having a substantially L-shaped cross section. As shown in fig. 6, the slide member 132 is disposed on the main body 111 of the housing 110 such that a bent upper corner portion 132A of an inner edge portion thereof faces the second cam portion 123 formed along a lower peripheral edge portion of the operating member 120. When the operation member 120 is pushed down, the upper corner portion 132A of the slide member 132 comes into contact with the second cam portion 123 of the operation member 120, and the slide member 132 is biased outward (outward in the radial direction of the operation member 120 with respect to the rotation axis) by the second cam portion 123 and slides outward. At this time, the slide member 132 generates a change in acceleration when the upper corner portion 132A passes through the apex of the second cam portion 123 in accordance with the shape of the second cam portion 123. Thereby, the slide member 132 gives a click feeling to the pressing operation by the operation member 120. On the other hand, when the pressing operation by the operation member 120 is released, the slide member 132 is biased inward (inward in the radial direction of the operation member 120 with respect to the rotation axis) by the repulsive force of the second plate spring 133, slides inward, and returns to the original position. At this time, the slide member 132 presses the second cam portion 123 of the operation member 120 inward by the upper corner portion 132A, thereby biasing the operation member 120 upward. Thereby, the operation member 120 is reset to the original position. That is, the click feeling providing mechanism 100 includes the second plate spring 133 and the slide member 132 as an example of "returning means" that, when the pressing operation of the operation member 120 is released, biases the slide member 132 inward in the radial direction of the rotation axis of the operation member 120 to return the operation member 120 to the initial position.
The second plate spring 133 is a member having spring characteristics, which is formed by processing a metal thin plate-like material. The second plate spring 133 is fixed to the back surface of the slide member 132 by a fixing mechanism such as an adhesive or a rivet. As shown in fig. 3 and 4, the second leaf spring 133 is assembled to a holding portion 111B formed in the peripheral wall portion of the body portion 111 of the housing 110 such that the slide member 132 faces the operation member 120. Thus, when the operation member 120 is pushed, the second plate spring 133 is deflected outward and generates a repulsive force as the slide member 132 slides outward (outward in the radial direction of the operation member 120 with respect to the rotation axis). When the pressing operation by the operation member 120 is released, the second plate spring 133 biases the slide member 132 inward (inward in the radial direction of the operation member 120 with respect to the rotation axis) by the repulsive force, and slides the slide member 132 inward. Thereby, the second plate spring 133 can return the slide member 132 to the original position and return the operation member 120 to the original position in conjunction therewith.
The cover plate 140 is a member formed by processing a metal thin plate-like material. As shown in fig. 5, the cover plate 140 has a thin plate-like annular portion 141 corresponding to the shape of the peripheral wall portion of the main body portion 111 of the housing 110. The cover plate 140 has the operation member 120 inserted through the opening of the annular portion 141, and the annular portion 141 covers the portion (the peripheral wall portion and the upper opening) of the main body 111 around the operation member 120. The cover plate 140 is fixed to the body 111 by a hook portion 142 that hangs downward from the outer peripheral edge of the annular portion 141 and a claw portion 111A provided on the outer peripheral surface of the side wall portion of the body 111. Thus, the cover plate 140 closes the peripheral wall portion and the upper opening of the main body 111, and prevents the operating member 120 from falling off the shaft portion 112, the members (the first plate spring 131, the second plate spring 133, and the slide member 132) accommodated in the peripheral wall portion of the main body 111, and the mixing of foreign substances into the main body 111.
Here, as shown in fig. 1 and 4, in the click feeling providing mechanism 100 of the present embodiment, the pair of first leaf springs 131 is assembled to the holding portion 111B formed in the peripheral wall portion of the main body portion 111 of the housing 110 so as to be disposed at positions (i.e., 180 ° apart) opposed to each other with the operation member 120 interposed therebetween. This can prevent the operation member 120 from being displaced with respect to the shaft 112 by the inward force from the first plate spring 131 (inward force of the operation member 120 in the radial direction with respect to the rotation axis).
As shown in fig. 1 and 4, in the click feeling providing mechanism 100 according to the present embodiment, the pair of slide members 132 and the second leaf spring 133 are assembled to the holding portion 111B formed in the peripheral wall portion of the main body portion 111 of the housing 110 so as to be disposed at positions facing each other (i.e., at 180 ° intervals) with the operating member 120 interposed therebetween. This can prevent the operating member 120 from being displaced with respect to the shaft portion 112 by the inward biasing force from the second plate spring 133 (inward of the operating member 120 in the radial direction with respect to the rotation axis).
In particular, as shown in fig. 1 and 4, in the click feeling providing mechanism 100 of the present embodiment, the pair of first leaf springs 131, and the pair of slide members 132 and second leaf springs 133 are arranged on the same circumference (i.e., at the same height position) in the peripheral wall portion of the main body portion 111 of the housing 110. Thus, the click feeling providing mechanism 100 of the present embodiment can reduce the thickness of the main body portion 111 of the housing 110.
In the click feeling providing mechanism 100 according to the present embodiment, the first leaf spring 131, the second leaf spring 133, and the slide member 132 can be arranged at predetermined positions simply by inserting the first leaf spring 131 and the second leaf spring 133 from above into the holding portion 111B formed in the peripheral wall portion of the main body portion 111 of the housing 110.
In particular, in the click feeling providing mechanism 100 according to the present embodiment, the first plate spring 131 and the second plate spring 133 have the same shape at both ends, which are portions inserted into the holding portion 111B. Therefore, the first leaf spring 131 and the second leaf spring 133 can be assembled to any one of the four holding portions 111B formed in the peripheral wall portion of the body portion ll1 of the case 110. That is, since the person in charge who performs the assembly work of the click feeling providing mechanism 100 does not need to pay attention to which holding portion 111B the first plate spring 131 and the second plate spring 133 are to be assembled, the assembly work of the click feeling providing mechanism 100 can be efficiently performed.
In addition, in the click feeling providing mechanism 100 of the present embodiment, the number of the first leaf springs 131 and the number of the second leaf springs 133 (and the slide members 132) can be easily changed. For example, by changing the number of the first plate springs 131, the load based on the rotational operation of the operating member 120 can be easily changed. Further, for example, by changing the number of the second leaf springs 133 (and the slide members 132), the load by the pressing operation of the operation member 120 can be easily changed.
[ example of operation accompanying rotational operation by the operation member 120 ]
Fig. 7 is a partially enlarged view showing an example of the operation member 120 in the click feeling providing mechanism 100 according to the embodiment. Fig. 7A shows a state in which the first plate spring 131 is pressed by the first cam portion 122 in association with the rotational operation by the operating member 120. Fig. 7B shows a state in which the first plate spring 131 is released from the pressing by the first cam portion 122 in association with the rotational operation by the operating member 120.
As shown in fig. 7, a plurality of first cam portions 122 protruding outward (outward in the radial direction of the operation member 120 with respect to the rotation axis) and in the horizontal direction are provided along the lower peripheral edge portion of the operation member 120.
As shown in fig. 7, the first plate spring 131 is disposed in a holding portion 111B formed in the peripheral wall portion of the main body portion 111 of the housing 110 such that the convex portion 131A of the first plate spring 131 faces the first cam portion 122 (i.e., faces inward in the radial direction of the operation member 120 with respect to the rotation axis).
When the operation member 120 is not rotated, the convex portion 131A of the first plate spring 131 is fitted between the adjacent two first cam portions 122 as shown in fig. 7B.
As shown in fig. 7A, when the operation member 120 is rotated in one direction (the direction of arrow D in the figure), the first cam portion 122 of the operation member 120 presses the convex portion 131A of the first plate spring 131 outward (the direction of arrow E in the figure) by the curved convex shape thereof, and is rotated and moved in one direction (the direction of arrow D in the figure).
Then, as shown in fig. 7B, when the operation member 120 is further rotated in one direction (arrow D direction in the figure), the first cam portion 122 of the operation member 120 returns the convex portion 13lA of the first plate spring 131 to the inner side (arrow F direction in the figure) by its curved convex shape, and further rotates in one direction (arrow D direction in the figure).
Then, as shown in fig. 7B, the convex portion 131A of the first plate spring 131 is fitted between the adjacent two first cam portions 122 again.
In this way, when the operating member 120 rotates, the resistance applied to the first cam portion 122 by the self repulsive force of the first plate spring 131 changes from the increasing state to the decreasing state, with the convex portion 131A of the first plate spring 131 passing through the apex of the convex shape of the first cam portion 122 as a boundary. At the same time, the first plate spring 131 changes the acceleration during the rotational movement of the first cam portion 122 from the deceleration state to the acceleration state, with the convex portion 131A of the first plate spring 131 passing through the apex of the convex shape of the first cam portion 122 as a boundary. When the convex portion 13lA of the first plate spring 131 is fitted again between the adjacent two first cam portions 122, the first plate spring 131 stops the rotational movement of the first cam portions 122 in an emergency. Thereby, the first plate spring 131 can give a click feeling to the rotational operation by the operation member 120.
[ example of an operation accompanying a pressing operation by the operation member 120 ]
Fig. 8 is a partially enlarged view showing an example of the operation member 120 in the click feeling providing mechanism 100 according to the embodiment according to the present invention. Fig. 8A shows a state of the slide member 132 when the pressing operation by the operation member 120 is not performed. Fig. 8B shows a state of the slide member 132 when the pressing operation by the operation member 120 is performed.
As shown in fig. 8A, the slide member 132 is disposed on the main body 111 of the housing 110 such that the curved upper corner 132A of the inner edge thereof faces the second cam portion 123 formed on the lower peripheral edge of the operating member 120.
As shown in fig. 8A, when the pressing operation by the operation member 120 is not performed, the upper corner portion 132A of the inner edge portion of the slide member 132 does not abut against the second cam portion 123 formed in the peripheral edge portion of the operation member 120. Thereby, the sliding member 132 does not apply a load to the rotating operation by the operating member 120.
On the other hand, as shown in fig. 8B, when the operation member 120 is pushed down, the operation member 120 moves downward (in the direction of arrow G in the figure). At this time, the second cam portion 123 of the operating member 120 abuts on the upper corner portion 132A of the slide member 132 due to the curved convex shape thereof, and biases the slide member 132 outward (in the direction of arrow H in the drawing). Thereby, the slide member 132 slides outward.
At this time, with respect to the slide member 132, when the upper corner portion 132A passes the apex of the second cam portion 123 in accordance with the convex shape of the second cam portion 123, the acceleration at the time of the slide movement changes from the deceleration state to the acceleration state. In conjunction with this, the acceleration of the operation member 120 when moving downward changes from the deceleration state to the acceleration state. When the lower surface of the first cam portion 122 of the operation member 120 abuts against the upper surface of the slide member 132, the downward movement of the operation member 120 is stopped urgently. Thus, the slide member 132 can provide a click feeling to the pressing operation by the operation member 120.
In the click feeling providing mechanism 100 of the present embodiment, the second cam portion 123 is continuously formed along the lower peripheral edge portion of the operation member 120 over the entire periphery. Therefore, in the click feeling providing mechanism 100 according to the present embodiment, regardless of the rotational position of the operation member 120, when the operation member 120 is pushed down, the slide member 132 can be slid outward while providing a click feeling by the second cam portion 123.
In the click feeling providing mechanism 100 according to the present embodiment, the click feeling during the pressing operation of the operating member 120 is determined by the convex shape of the second cam portion 123 and the shape of the upper corner portion 132A of the slide member 132. Therefore, in the click feeling providing mechanism 100 according to the present embodiment, by adjusting at least one of the convex shape of the second cam portion 123 and the shape of the upper corner portion 132A of the slide member 132, it is possible to provide various click feelings to the pressing operation by the operation member 120.
As described above, in the click feeling providing mechanism 100 according to the present embodiment, when the operation member 120 is rotationally operated, the convex portion 131A of the first plate spring 131 abuts against the first cam portion 122 formed in the peripheral edge portion of the operation member 120, and a click feeling can be provided to the rotational operation. In the click feeling providing mechanism 100 according to the present embodiment, when the operation member 120 is pushed down, the slide member 132 is slidable outward (outward in the radial direction of the operation member 120 with respect to the rotation axis) by coming into contact with the second cam portion 123 formed in the peripheral edge portion of the operation member 120, and provides a click feeling to the pushing down operation. Thus, the click feeling providing mechanism 100 of the present embodiment can provide a click feeling to a pressing operation without disposing a structure for providing a click feeling to a pressing operation below the operation member 120. Therefore, according to the click feeling providing mechanism 100 of the present embodiment, a thin operation mechanism capable of providing a click feeling to both the pressing operation and the rotating operation by the operation member can be provided.
In the click feeling providing mechanism 100 according to the present embodiment, the first plate spring 131 (first click feeling providing means) and the slide member 132 (second click feeling providing means) are arranged on the same circumference. That is, in the click feeling providing mechanism 100 of the present embodiment, the first plate spring 131 and the slide member 132 can be provided at the same height position. Therefore, according to the click feeling providing mechanism 100 of the present embodiment, a thin operation mechanism capable of providing a click feeling to both the pressing operation and the rotating operation by the operation member can be provided.
In the click feeling providing mechanism 100 according to the present embodiment, the pair of first leaf springs 131 (first click feeling providing means) and the pair of slide members 132 (second click feeling providing means) are provided so as to face each other with the operation member 120 interposed therebetween. Thus, in the click feeling providing mechanism 100 according to the present embodiment, the operation member 120 can be prevented from being displaced with respect to the shaft portion 112 by the inward biasing force from the first plate spring 131 (inward in the radial direction of the operation member 120 with respect to the rotation axis). In addition, in the click feeling providing mechanism 100 of the present embodiment, the operation member 120 can be prevented from being displaced with respect to the shaft portion 112 by the inward force from the slide member 132 (inward force of the operation member 120 in the radial direction with respect to the rotation axis).
In addition, the click feeling providing mechanism 100 of the present embodiment uses the first plate spring 131 as the first click feeling providing means. The click feeling providing mechanism 100 according to the present embodiment uses the second plate spring 133 as a returning means provided in the second click feeling providing means for returning the operation member 120 to the initial position by biasing the slide member 132 inward (inward in the radial direction of the operation member 120 with respect to the rotation axis). Thus, the click feeling providing mechanism 100 of the present embodiment can reduce the radial dimension of the operation member 120 with respect to the rotation axis of the first click feeling providing means and the second click feeling providing means. That is, the size of the body 111 of the housing 110 in the radial direction can be reduced.
In the click feeling providing mechanism 100 according to the present embodiment, the plurality of holding portions 111B that hold the first plate spring 131 and the second plate spring 133 have shapes that can hold both the first plate spring 131 and the second plate spring 133. Thus, in the click feeling providing mechanism 100 according to the present embodiment, the person in charge who performs the operation of assembling the click feeling providing mechanism 100 does not need to pay attention to which holding portion 111B the first plate spring 131 and the second plate spring 133 are assembled, and therefore, the operation of assembling the click feeling providing mechanism 100 can be efficiently performed.
In the click feeling providing mechanism 100 according to the present embodiment, each of the operation member 120 and the shaft portion 112 of the housing 110 has a hollow structure. Thus, in the click feeling providing mechanism 100 according to the present embodiment, for example, when the click feeling providing mechanism 100 is attached to the surface of the touch panel, the user can visually recognize the display information displayed in the display region corresponding to the hollow portion. Note that, the present invention is not limited to this, and at least one of the operation member 120 and the shaft portion 112 of the housing 110 may have a hollow structure.
While one embodiment of the present invention has been described above in detail, the present invention is not limited to the above embodiment, and various modifications and changes can be made within the scope of the present invention described in the claims.
The present invention is not limited to the click feeling providing mechanism, and can be applied to any device that can perform a rotation operation and a pressing operation. For example, in the click feeling providing mechanism 100 according to the above-described embodiment, a structure (e.g., a wire, a terminal, or the like) that enables electrical connection and operation may be provided to at least one of the rotation operation and the pressing operation by the operation member 120. That is, the click feeling providing mechanism 100 of the above embodiment may have a function of a rotary switch, a push switch, or the like.
For example, in the click feeling providing mechanism 100 according to the above embodiment, three or more first leaf springs 131 may be provided to the main body portion 111 of the housing 110.
For example, in the click feeling providing mechanism 100 according to the above embodiment, the main body portion 111 of the housing 110 may be provided with three or more sets of the slide member 132 and the second plate spring 133.
For example, in the click feeling providing mechanism 100 according to the above embodiment, the first leaf spring 131 and the second leaf spring 133 may be integrally formed. Thereby, it is possible to provide both the rotation operation and the pressing operation by the operation member 120 with a click feeling at the same position in the circumferential direction.
In the click feeling providing mechanism 100 according to the above embodiment, another biasing member (for example, a coil spring, an elastic rubber, or the like) may be used instead of the first plate spring 131. Similarly, in the click feeling providing mechanism 100 of the above embodiment, another urging member (for example, a coil spring, elastic rubber, or the like) may be used instead of the second plate spring 133.
[ modified example ]
Fig. 9 is a perspective view showing a click feeling providing mechanism 100A (a state where the cover plate 140 is removed) according to a modification. Fig. 10 is a plan view showing a click feeling providing mechanism 100A (a state where the cover plate 140 is removed) according to a modification.
The click feeling providing mechanism 100A shown in fig. 9 and 10 is different from the click feeling providing mechanism 100 in that it includes a click feeling providing member 150 instead of the first plate spring 131, the slide member 132, and the second plate spring 133. The click feeling providing member 150 is an example of a member in which the "first click feeling providing means" and the "second click feeling providing means" are integrated.
As shown in fig. 9 and 10, the click feeling providing mechanism 100A of a modification includes four click feeling providing members 150, and the four click feeling providing members 150 are respectively assembled to four holding portions 111B formed at 90 ° intervals in the peripheral wall portion of the main body portion 111 of the housing 110.
Fig. 11 is an enlarged view showing a click feeling providing member 150 provided in a click feeling providing mechanism 100A according to a modification. As shown in fig. 11, the click feeling providing member 150 includes a slide member 151 and a third leaf spring 152.
The slide member 151 has substantially the same shape as the slide member 132. That is, the slide member 151 is a member having a substantially L-shaped cross section, and has a curved upper corner portion 151A formed in an inner edge portion thereof, similarly to the slide member 132. However, the slide member 151 is different from the slide member 132 in that a projection 153 projecting inward (inward in the radial direction of the operation member 120 with respect to the rotation axis) is additionally provided on a wall portion formed on the outer side (outward in the radial direction of the operation member 120 with respect to the rotation axis). The convex portion 153 has a curved convex shape, similar to the convex portion 131A of the first plate spring 131, and is provided for giving a click feeling to a rotational operation by the operation member 120.
The third leaf spring 152 is a member having spring characteristics, which is formed by processing a metal thin plate-like material, like the second leaf spring 133. The third plate spring 152 is fixed to the back surface of the slide member 151 by a fixing mechanism such as an adhesive or a rivet.
In the click feeling providing mechanism 100A configured as described above, when the operation member 120 is pushed down, the second cam portion 123 of the operation member 120 abuts on the upper corner portion 151A of the slide member 151 due to the curved convex shape thereof, and biases the slide member 151 outward (outward in the radial direction of the operation member 120 with respect to the rotation axis). Thereby, the sliding member 151 slides outward.
At this time, when the upper corner portion 151A passes the apex of the second cam portion 123 in accordance with the convex shape of the second cam portion 123, the acceleration at the time of the sliding movement changes from the deceleration state to the acceleration state with respect to the slide member 151. In conjunction with this, the acceleration of the operation member 120 when moving downward changes from the deceleration state to the acceleration state. When the lower surface of the first cam portion 122 of the operation member 120 abuts against the upper surface of the slide member 151, the downward movement of the operation member 120 is stopped urgently. Thereby, the slide member 151 can give a click feeling to the pressing operation by the operation member 120.
In the click feeling providing mechanism 100A, when the operation member 120 is not rotated, the convex portions 153 of the four slide members 151 are fitted between the adjacent two first cam portions 122 as shown in fig. 9 and 10.
On the other hand, in the click feeling providing mechanism 100A, when the operation member 120 is rotationally operated, the convex portions 153 of the four slide members 151 are pressed outward (outward in the radial direction of the operation member 120 with respect to the rotation axis) by the first cam portions 122 of the operation member 120. At this time, the resistance given to the first cam portion 122 by the repulsive force from the third plate spring 152 changes from the increasing state to the decreasing state for each convex portion 153, with the apex of the convex shape passing through the first cam portion 122 as a boundary. At the same time, the acceleration during the rotational movement of the first cam portion 122 is changed from the deceleration state to the acceleration state for each convex portion 153, bounded by the apex of the convex shape of the first cam portion 122. When the convex portions 153 are fitted into the space between the adjacent two first cam portions 122 again, the rotational movement of the first cam portions 122 is stopped urgently. Thus, each convex portion 153 can provide a click feeling to the rotational operation by the operation member 120.
