Since the depth of the return cam 26c gradually becomes shallow toward the both ends of the groove, a return operation force for always returning to the neutral posture acts on the second slide member 26.

  As shown in FIGS. 2 and 4, a falling operation member 31 is provided in the case. The tilting operation member 31 is made of synthetic resin, and a sliding hole 31a penetrating in the vertical direction is formed at the central portion. At least a part of the slide hole 31a is square in cross section. A part of the operation shaft 4 is also a square in cross section, and the square portion of the operation shaft 4 is inserted into a portion of the slide hole 31 a whose section is a square. Therefore, although the operation shaft 4 is axially slidable inside the slide hole 31 a, the operation shaft 4 and the tilting operation member 31 are mutually restrained in the rotation direction of the operation shaft 4. The falling operation member 31 rotates together.

  The upper portion of the tilting member 31 is located inside the central hole 21 of the guide member 20. A sliding surface 31 b of a spherical shape is formed on the middle part of the falling member 31. As shown in FIG. 4, a concave spherical guide surface 20 a is formed on the lower inner surface of the guide member 20, and the sliding surface 31 b slides on the guide surface 20 a to move together with the operation shaft 4. 31 is free to fall. The sliding surface 31 b of the tilting operation member 31 and the guide surface 20 a of the guide member 20 constitute a tilting guide mechanism for guiding the tilting operation of the operation shaft 4.

The flanges 31c are formed with connecting protrusions 31d extending in the X and Y directions, and the rotary member 33 is formed with connecting recesses 33a corresponding to the respective connecting protrusions 31d. The respective connection protrusions 31d enter the inside of the connection recess 33a, and when the operation shaft 4 and the tilting operation member 31 rotate, the rotation member 33 can also rotate together. However, since the connecting projection 31d can move up and down in the connecting recess 33a, the rotating member 33 does not tilt when the operation shaft 4 and the tilting operation member 31 tilt.

  As shown in FIG. 2, on the upper surface of the rotating member 33, concavo-convex portions 33 b arranged at a constant pitch in the circumferential direction are formed, and resiliently pressing of the plate spring 34 fixed to the lower end of the guide member 20 The portion 34a is pressed against the uneven portion 33b. As a result, when the operation shaft 4 rotates and the rotating members 33 rotate together, a rotational click feeling can be generated.

  At the lower part of the rotation member 33, detection pieces 33c arranged at a constant pitch in the circumferential direction are integrally formed. The insulating substrate 13 in the lower case 2 is provided with an optical detection unit (not shown) as a rotation detection unit to constitute a rotation detection unit. When the rotation member 33 rotates with the operation shaft 4, the detection piece 33c is sequentially detected by the optical detection unit, whereby the rotation operation of the operation shaft 4 can be detected.

A force Fx is applied, and the second slide member 26 moves in the X direction. Since the inner diameter of the insertion hole 26a formed in the second slide member 26 is larger than the diameter of the operation shaft 4, the operation shaft 4 can be inclined inside the insertion hole 26a, and at this time, the ring body 29 freely expands and contracts. can do.

  When the operation shaft 4 tilts, the tilt operation member 31 mounted on the outer periphery of the operation shaft 4 falls together. The actuator 32 located on the lower side is inclined by the tilting operation of the tilting operation member 31, and one or two of the eight pressing protrusions 32a provided on the lower surface of the actuator 32 are positioned in the tilting direction. The elastic portion 12 of the membrane 10 is pushed. The conductor provided on the lower surface of the pressed peripheral elastic portion 12 contacts the pair of conductive portions of the peripheral contact portion 15, the conductive portions are electrically connected to each other, and the inclination detection portion operates. An inclination is detected.

  As shown in FIG. 6, when the second slide member 26 is moved in the X direction by the tilting operation of the operation shaft 4, the return head 26 a of the return pin 27 is formed on the second slide member 26. Because the sliding head 27a applies a pressing force to the return cam 26c from the sliding head 27a by the return spring 28, the second slide member 26 is returned to the neutral position shown in FIGS. Recovery force works. Therefore, when the application of the force for performing the tilting operation is stopped, the operating shaft 4 returns to the neutral posture shown in FIGS. 4 and 5.

8 and 9 show the pressing operation of the operating shaft 4.
When the operation shaft 4 is pushed in, the operation shaft 4 slides downward in the sliding hole 31a formed in the tilting operation member 31, and the pressing spacer 8 is pushed downward by the base 4a of the operation shaft 4.

Operate.

  At this time, as shown in FIGS. 8 and 9, the ring body 29 held by the operation shaft 4 is separated from the inclined portion 26 b formed in the second slide member 26. Therefore, the presence of the ring body 29 does not become a load of the pushing operation of the operation shaft 4.

  Next, when the operation shaft 4 is rotated, the tilt operation member 31 is rotated together with the operation shaft 4, and the rotation member 33 is further rotated together, and the rotation detection unit is operated. At this time, the ring body 29 held by the operation shaft 4 slides on the inclined portion 26 b of the second slide member 26. Since the ring body 29 has a circular cross section, the frictional resistance between the ring body 29 and the inclined portion 26b is also extremely reduced. Therefore, the rotation operation of the operation shaft 4 can also be smoothly performed.
