PROBLEM TO BE SOLVED: To provide a tilt device bearing use of a long time by preventing a load imparting part from deteriorating with a lapse of time. SOLUTION: The tilt device is provided with an oscillating body 10, which oscillates with respect to an oscillation fulcrum 11 so as to take a first attitude and a second attitude and is also capable of taking an attitude between the first/second attitudes, support members 4, 9 for swingably supporting the oscillating body 10, and a load imparting part 20 that is provided between the oscillating body 10 and the support members 4, 9 so as to impart an oscillation load to the oscillating body 10 when the oscillating body 10 is located between the first/second attitudes and not to impart an oscillation load to the oscillating body 10 when the oscillating body 10 is located at least at either of the first/second attitude positions.
