So far, the configuration of the joystick device 100 has been described. From here, the operation of the joystick device 100 will be described with reference to the drawings.

When the user operates the operating lever 103, the operating member 117 receives a force in any one direction in the front, rear, left, and right planes. Here, a case where the operating member 117 receives a force in the left direction in response to the operation of the user will be described as an example.

When the operating member 117 receives a force in the left direction from the neutral state, the flange lower surface 132 is tilted to the left while being supported by contacting the contact portion 137 of the support portion 134. Since the columnar portion 123 is fitted with the input shaft portion 108, as shown in the cross-sectional view of FIG. 4, the fitting hole portion 126 has a right end portion in the vicinity of the right end portion of the input shaft portion 108, and the input shaft portion 126 has an input shaft portion. Push 108 to the left. As a result, the operating member 117 is tilted to the left along with the input shaft portion 108 about the rotation center RC1.

When the operating member 117 receives a force further to the left from the tilted state shown in FIG. 4, as shown in FIG. 5, the columnar portion 123 (specifically, the second columnar portion 128) becomes the second operation restricting member 119. Tilt to the left until it comes into contact with the opening 143.

Here, the state shown in FIG. 5, that is, the state in which the lower surface of the flange portion 124 is in contact with the entire contact portion 137 of the support member 118 and the operation member 117 is in contact with the operation regulation member 119 at one place is the first state. It is called a contact state.

Since the columnar portion 123 is fitted with the input shaft portion 108, the fitting hole portion 126 has the input shaft portion 108 near the right end thereof while tilting from the neutral state to the first contact state, as in the above case. It hits the vicinity of the right end and pushes the input shaft portion 108 to the left. During this period, as in the above case, the operating member 117 is supported by the support portion 134 with the flange lower surface 132 in contact with the contact portion 137 of the support portion 134. As a result, the operating member 117 is tilted to the left along with the input shaft portion 108 about the rotation center RC1 until the second columnar portion 128 comes into contact with the second opening 143 of the operating restricting member 119.

As described above, when the allowable range of inclination of the input shaft portion 108 is 0 to 8 degrees with respect to the central axis CA by design, the inner diameter of the second opening 143 and the outer diameter of the second columnar portion 128 are In the first contact state shown in FIG. 5, the input shaft portion 108 may be set so as to be tilted approximately 8 degrees with respect to the central axis CA about the rotation center RC1.

Here, since the flange lower surface 132 has a spherical shape that is convex upward, the operating member 117 can be smoothly tilted about the rotation center RC1. In particular, in the present embodiment, the center of the spherical surface formed by the lower surface 132 of the flange is common to the center RC1 of the tilt of the input shaft portion 108. Therefore, the operating member 117 can be tilted extremely smoothly around the rotation center RC1.

Further, as can be seen from FIG. 5, in the first contact state, the contact portion between the columnar portion 123 and the second opening 143 is such that the columnar portion 123 and the input shaft portion 108 are located at the axial position of the columnar portion 123. Included in the fitting area. The region where the columnar portion 123 fits with the input shaft portion 108 corresponds to the fitting hole portion 126 of the present embodiment. That is, the portion that comes into contact with the second opening 143 in the first contact state is located on the side of the fitting hole portion 126 (in the direction perpendicular to the axis of the columnar portion 123). As a result, the columnar portion 123 can be shortened in the axial direction as compared with the case where the portion in contact with the second opening 143 in the first contact state is not located on the side of the fitting hole portion 126. Therefore, the protection unit 104 can be miniaturized.

It is assumed that a force in the left direction is further received from the first contact state shown in FIG. As described above, the fitting of the input shaft portion 108 and the fitting hole portion 126 is a fitting having a gap. Therefore, at this time, the operating member 117 is tilted to the left with respect to the input shaft portion 108. Can be done. Then, in a state where the contact between the columnar portion 123 and the second opening 143 is maintained, the flange portion 124 of the operating member 117 is the operation restricting member 119 (specifically, the second opening), as shown in FIG. It can be tilted to the left with respect to the input shaft portion 108 until it comes into contact with the lower end portion of 143).

Here, in the state shown in FIG. 6, that is, the operating member 117 comes into contact with the operating restricting member 119 at two locations, the columnar portion 123 (specifically, the second columnar portion 128) and the flange upper surface 131, and further, the flange lower surface. The state in which 132 is in contact with the contact portion 137 is referred to as a second contact state.

That is, when the operating member 117 receives a force further to the left from the first contact state, the contact between the columnar portion 123 and the second opening 143 is maintained, and the operating member 117 tilts to the left with respect to the input shaft portion 108.

In the second contact state shown in FIG. 6, the operating member 117 comes into contact with the operation restricting member 119 at two locations, the columnar portion 123 (specifically, the second columnar portion 128) and the flange upper surface 131, and further, the flange lower surface. 132 is in contact with the contact portion 137. Therefore, the operating member 117 cannot be tilted further to the left even if it receives a force further to the left from the second contact state.

The fitting of the input shaft portion 108 and the fitting hole portion 126 is a fitting having a gap 130. The gap 130 according to the present embodiment has a size such that the input shaft portion 108 can freely move in the fitting hole portion 126 from the first contact state to the second contact state. That is, the size is such that the input shaft portion 108 does not receive a force further tilting to the left from the operation member 117 while the operation member 117 is tilted with respect to the input shaft portion 108.

Therefore, even if the operating member 117 is tilted from the first contact state to the second contact state, the magnitude of the force applied to the input shaft portion 108 during that time is almost the same as that of the first contact state. Therefore, according to the present embodiment, it is possible to reduce the possibility of damaging the input element due to an excessive load when the operating member receives a force corresponding to the operation of the user.

In the embodiment, the gap 130 has a size that allows the input shaft portion 108 to move freely in the fitting hole portion 126 from the first contact state to the second contact state. However, the fitting of the input shaft portion 108 and the fitting hole portion 126 may be any fitting having a gap 130 (loose fitting). According to this, it is possible to reduce the magnitude of the force applied to the input shaft portion 108 when the operating member 117 is tilted from the first contact state to the second contact state. Therefore, when the operating member receives a force corresponding to the operation of the user, it is possible to reduce the possibility of damaging the input element due to an excessive load.

Further, in the embodiment, the operation member 117 contacts the operation restricting member 119 at two places, the columnar portion 123 (specifically, the second columnar portion 128) and the flange upper surface 131, and the flange lower surface 132 contacts the contact portion. The state of contact with 137 was defined as the second contact state. However, the second contact state is the second contact state by adjusting the positional relationship between the columnar portion 123 (specifically, the second columnar portion 128) and the flange upper surface 131 with respect to the operation restricting member 119. Even if a force is further applied to the left, it is sufficient as long as the vehicle cannot tilt further to the left. For example, the second contact state may be a state in which the operation member 117 is in contact with the operation regulation member 119 only at two locations, the columnar portion 123 (specifically, the second columnar portion 128) and the flange upper surface 131.
