[0036] Please refer to Figures 1 to 5As shown, the input device 100 comprises a housing 1 having an upper shell 11 made of metal and an insulating lower shell 12 assembled with the upper shell 11. The upper shell 11 comprises an upper wall portion 111 provided with an opening portion, four side wall portions 112 extending downwardly and bending from the periphery of the upper wall portion 111, and the lower shell 12 is fixed to the lower end of the upper shell 11 to form a bottom wall portion, and a receiving space 113 is formed between the upper wall portion 111 and the side wall portions 112 of the upper shell 11 and the lower shell 12. The input device 100 further comprises an operation member 2 inserted into the receiving space 113 through the opening portion and capable of performing a tilting operation, a first driving element 3 arranged in the receiving space 113 and linked with the operation member 2, the first driving element 3 rotating as the operation member 2 tilts in a first direction, a first rotary electric component 4 detected in conjunction with the rotating action of the first driving element 3, a second driving element 5 arranged in the receiving space 113, the second driving element 5 being located below the first driving element 3 and orthogonal to the first driving element 3, a second rotary electric component 6 detected in conjunction with the rotating action of the second driving element 5, and a restoring mechanism 7 restoring the first driving element 3 and the second driving element 5 to an initial state by means of the operation member 2.

[0037] Please refer to Figures 6 to 9 As shown, the first driving element 3 is linked with the operation member 2, and the first driving element 3 rotates as the operation member 2 tilts in a first direction. The first driving element 3 is provided with a first through hole 31 for inserting the operation member 2, and the first driving element 3 has a first shaft portion 32 and a second shaft portion 33 located on both sides of the first through hole 31 in a second direction perpendicular to the first direction. The second shaft portion 33 cooperates with the first rotary electric component 4. The lower shell 12 is provided with a base for supporting the first shaft portion 32 and the second shaft portion 33. The base comprises a first base 121 for supporting the first shaft portion 32 and a second base 122 for supporting the second shaft portion 33. The first base 121 and the second base 122 respectively have an inner side close to the operation member 2 in the second direction and an outer side opposite to the inner side.

[0038] The first shaft portion 32 and the second shaft portion 33 are each provided with a circular arc surface to enable the first actuating element 3 to rotate in the first direction. The circular arc surface of the first shaft portion 32 has a curvature greater than that of the circular arc surface of the second shaft portion 33. The first base 121 supporting the first shaft portion 32 and the second base 122 supporting the second shaft portion 33 are each provided with a slot 123 to match the circular arc surface. The slot 123 is provided as an arc-shaped structure with an opening upward. The side wall portion 112 of the upper shell 11 is provided with a mounting opening 1121 with an opening downward, which, together with the slot 123, clamps the first shaft portion 32 and the second shaft portion 33 to limit the relative movement between the first actuating element 3 and the outer shell 1 in the up-down direction.

[0039] In combination Figure 10 As shown, the first shaft portion 32 includes a first protrusion 321 inside the first base 121 and a second protrusion 322 outside the first base 121 to limit the relative movement between the first actuating element 3 and the lower shell 12 in the second direction. In the initial state, the lowermost end of the second protrusion 322 in the up-down direction is level with the lowermost end of the slot 123 in the first base 121, which can save the internal space of the input device 100. The lowermost end of the first protrusion 321 is lower than the lowermost end of the slot 123 in the first base 121 to ensure more reliable limiting. The second shaft portion 33 has a third protrusion 331 outside the second base 122, and the lowermost end of the third protrusion 331 in the up-down direction is lower than the lowermost end of the slot 123 in the second base 122. The second shaft portion 33 only has the third protrusion 331 outside the second base 122 as a limiting structure, and in other embodiments, the second shaft portion 33 can also have a limiting structure inside the second base 122. The first actuating element 3 also includes an extension 34 extending outward from the second shaft portion 33 in the second direction. When the first rotary electrical component 4 is installed on the extension 34 of the first actuating element 3, it will push the first actuating element 3 to move in the second direction, and the first protrusion 321 and the third protrusion 331 will abut against the second base 122 and the first base 121 to limit the relative movement between the first actuating element 3 and the lower shell 12. The first protrusion 321 and the third protrusion 331 are located on the same side of the first actuating element 3, and when assembled, the first actuating element 3 still has the risk of falling off. The second protrusion 322 and the first protrusion 321 clamp the first base 121 together, and the two sides of the first base 121 jointly stop and limit, which effectively prevents the first actuating element 3 from falling off.
