(Operation)
FIG. 6 is a plan view of the operating lever device 100 in a state where the operating lever 140 is in the initial position. The operation lever 140 can rotate in both the first rotation direction 104 and the second rotation direction 105 around the second virtual center axis 103 (FIG. 7). FIG. 10 is a plan view of the operation lever device 100 in a state where the operation lever 140 is rotated in the second rotation direction 105. In FIG. 10, the first housing 110 and the second housing 120 are omitted.

First, the case where the operation lever 140 is rotated in the second rotation direction 105 from the initial position shown in FIG. 6 will be described. When the transmission portion 163 in the second restriction hole 198-2 pushes the second contact portion 193-2 in the x1 direction, the second drive portion 190-2 rotates as shown in FIG. The rotating body 150 rotates along the first support surface 196-1 and the first opposing support surface 197-1 of the first drive unit 190-1. The transmission unit 163 moves along the first restriction hole 198-1 (FIG. 7) without pressing the first drive unit 190-1. That is, the first drive unit 190-1 remains at the initial position shown in FIG. The amount of movement of the transmission part 163 is limited by the length of the first restriction hole 198-1 (FIG. 7) along the xy plane.

In the state shown in FIG. 10, when the operation lever 140 is rotated in the first rotation direction 104, the transmission portion 163 in the second restriction hole 198-2 pushes the second contact portion 193-2 in the x2 direction. Then, the second drive unit 190-2 returns to the initial position shown in FIG. The transmission unit 163 moves along the first restriction hole 198-1 (FIG. 7) without pressing the first drive unit 190-1. That is, the first drive unit 190-1 remains at the initial position shown in FIG.

When the transmission unit 163 moves, the actuator 170 urged toward the uneven surface 131 of the cam unit 130 shown in FIG. 5 moves along the uneven surface 131 and causes the operator to change the resistance force through the operation lever 140. The feeling of operation is transmitted. The operation when the operation lever 140 is rotated in the first rotation direction 104 from the initial position shown in FIG. 6 is symmetric with the operation when the operation lever 140 is rotated in the second rotation direction 105, and thus the description thereof is omitted.

FIG. 7 is a side view of the operation lever device 100 in a state where the operation lever 140 is in the initial position. The operation lever 140 can rotate in both directions of the third rotation direction 106 and the fourth rotation direction 107 around the first virtual center axis 102 (FIG. 6). FIG. 11 is a side view of the operation lever device 100 in a state where the operation lever 140 is rotated in the third rotation direction 106. In FIG. 11, the first housing 110 and the second housing 120 are omitted.

First, the case where the operation lever 140 is rotated in the third rotation direction 106 from the initial position shown in FIG. 7 will be described. When the transmission portion 163 in the first restriction hole 198-1 pushes the first contact portion 193-1 in the z2 direction, the first drive portion 190-1 rotates as shown in FIG. The rotating body 150 rotates along the second support surface 196-2 and the second opposing support surface 197-2 of the second drive unit 190-2. The transmission unit 163 moves along the second restriction hole 198-2 (FIG. 6) without pressing the second drive unit 190-2. That is, the second drive unit 190-2 remains at the initial position shown in FIG. The amount of movement of the transmission part 163 is limited by the length of the second restriction hole 198-2 (FIG. 7) along the yz plane.

When the operation lever 140 is rotated in the fourth rotation direction 107 in the state shown in FIG. 11, the transmission portion 163 in the first restriction hole 198-1 pushes the first contact portion 193-1 in the z1 direction. The first drive unit 190-1 returns to the initial position shown in FIG. The transmission unit 163 moves along the second restriction hole 198-2 (FIG. 6) without pressing the second drive unit 190-2. That is, the second drive unit 190-2 remains at the initial position shown in FIG.

When the transmission portion 163 moves, as shown in FIG. 5, the actuator 170 biased toward the uneven surface 131 of the cam portion 130 moves along the uneven surface 131, and resists the operator through the operation lever 140. A feeling of operation as a change of is transmitted. Since the operation when the operation lever 140 rotates in the fourth rotation direction 107 from the initial position shown in FIG. 7 is symmetric with the operation when the operation lever 140 rotates in the third rotation direction 106, the description is omitted.

The first housing 110 and the second housing 120 are made of resin reinforced with glass fiber and withstand a strong force. The cam portion 130, the operation lever 140, and the actuator 170 are made of resin. Since the coupling member 160 is made of a metal such as iron or aluminum, the operation lever 140 and the rotating body 150 can be fixed with high accuracy and in a state of being difficult to be deformed as compared with the case of being made of resin. The elastic member 180 is a metal winding spring. The elastic member 180 may be another member that can bias the actuator 170. The rotating body 150 is made of a slidable molding resin such as POM (polyacetal). Since the first driving unit 190-1 and the second driving unit 190-2 are formed of a softer resin than the first casing 110 and the second casing 120, the first casing 110 and the second casing The rotating body 150 is less likely to be damaged than the case where the rotating body 150 is directly supported.

Although there are two drive units 190 in the present embodiment, in another example, the number of drive units 190 may be one, or three or more.

(Summary)
According to the present embodiment, the rotation surface 151 is rotatably supported by the support surface 196 and the opposing support surface 197 of the drive unit 190. Thereby, compared with the case where protrusion is provided in the surface of the rotation surface 151 like the past, it becomes possible to take the area which supports the rotation surface 151, and can improve durability. In addition, since the number of parts can be reduced as compared with the conventional case where the rotating surface 151 is supported using a member other than the driving unit 190, assembly is facilitated.

According to this embodiment, the contact portion 193 connecting the support portion 191 and the opposing support portion 192 can contact the transmission portion 163 on the movement path of the transmission portion 163 that rotates as the rotating body 150 rotates. Therefore, the configuration for transmitting the operation from the operation lever 140 to the drive unit 190 is simpler and easier to assemble than when a member other than the contact portion 193 is provided.

According to the present embodiment, the contact portion 193 has the restriction hole 198 partially extending between the support portion 191 and the opposing support portion 192, and the transmission portion 163 extends from the rotating body 150 to the inside of the restriction hole 198. Therefore, the transmission of the operation from the operation lever 140 to the plurality of drive units 190 and the restriction of the operation amount of the operation lever 140 can be easily realized by the restriction hole 198 of the contact portion 193.

According to the present embodiment, since the transmission part 163 extends from the rotating body 150 into all the restriction holes 198 of the two or more drive parts 190, the two or more drive parts 190 can be connected to the 1 with a simple configuration. It can be moved by one transmission part 163.

According to the present embodiment, the cam unit 130 having the uneven surface 131, the actuator 170 movably held by the transmission unit 163, and the elastic member 180 that biases the actuator 170 toward the uneven surface 131 are further provided. Therefore, compared with the case where the actuator 170 is held by another member, the number of parts is small and it is easy to assemble.

According to the present embodiment, since the plurality of driving units 190 are provided, the rotation of the rotating body 150 in different directions can be detected by the driving unit 190, and the rotation is performed by the plurality of support surfaces 196 and the plurality of opposing support surfaces 197. The body 150 can be stably supported.

According to the present embodiment, since the two drive units 190 rotate around the first virtual center axis 102 and the second virtual center axis 103 that are orthogonal to each other, the rotation surface 151 is supported in a balanced manner from two directions. Can do.

According to this embodiment, at the time of assembly, first, in the first housing 110, the first shaft portion 194-1 is placed in the first recess 116, and the second shaft portion 195-1 is placed in the second recess 117, The third shaft portion 194-2 is fitted into the third recess 118. Next, the first casing 110 and the second casing 120 are combined, the first shaft portion 194-1 is sandwiched between the first recess 116 and the first opposing recess 126, and the second recess 117 and the second recess The operation lever device 100 can be easily assembled by inserting the second shaft portion 195-1 between the opposing recess 127 and inserting the fourth shaft portion 195-2 into the fourth recess 128.

According to the present embodiment, the operating lever 140 and the rotating body 150 are separate parts, and the operating lever 140 and the rotating body 150 are coupled by the coupling member 160. Compared to a single member, it is possible to easily cope with various changes. The operating lever 140 and the rotating body 150 can be made of different materials suitable for each.

According to this embodiment, the outer shape of the coupling member 160 is substantially columnar, the operation lever 140 has the first fixing hole 143 along the outer shape of the coupling member 160, and the rotating body 150 is the outer shape of the coupling member 160. The coupling member 160 is fixed in the second fixing hole 152, and the coupling member 160 includes a base 162 extending outward from the second fixing hole 152. However, since it is fixed in the first fixing hole 143 by the pressure between the base 162 and the operation lever 140, the operation is performed simply by fitting the coupling member 160 fixed to the second fixing hole 152 into the first fixing hole 143. The lever 140 and the rotating body 150 can be easily coupled.

According to the present embodiment, the cam portion 130, the actuator 170, and the elastic member 180 are further provided, the base portion 162 protrudes from the first opening 153 of the second fixing hole 152, and the coupling member 160 is the second fixing hole. 152 further includes a transmission portion 163 projecting from the other second opening 154 of the 152, and the actuator 170 is movably held by the transmission portion 163. Therefore, the component is compared with the case where the actuator 170 is held by another member. Easy to assemble with few points.

According to the present embodiment, since the actuator 170 is slidably held by the storage hole 161 of the metal coupling member 160, the size of the storage hole 161 is larger than when the coupling member 160 is made of resin. Can be managed with high accuracy. Therefore, rattling during the operation of the actuator 170 can be prevented and the operational feeling can be enhanced.

According to the present embodiment, since the rotating body 150 is made of a slidable molding resin and the coupling member 160 is made of metal, the operability is improved by sliding the rotating body 150 smoothly and at the same time. The required strength can be ensured.
