<p>PROBLEM TO BE SOLVED: To provide the tilt mechanism of the operation input device which is simple in structure, easily assembled, and good in operability. SOLUTION: The tilt mechanism 4 consists of a recessed part 41 formed in the bottom surface of a lower case 3, a leg member 43 which is supported rotatably on a bearing part in the recessed part 41 by a support shaft 44, and a coil spring 45 which has one end engaged with the leg member 43 and lower end engaged with the lower case 3 and energizes the leg member 43 so that it projects from in the recessed part 41, and the coil spring 45 has an energizing force which is small enough not to project the leg member 43 when a mount surface and the bottom surface of the lower case 3 are gravitationally in contact. Consequently, the structure becomes simple and the assembly is also made easy. Further, the leg member 43 can easily be opened and closed and the tilt mechanism of the operation input device is provided which has good operability.</p> |
