Abstract: A seat device equips a walk-in mechanism and a fold down mechanism (a seatback is turned down with large angle so as to attain the flat condition). These mechanisms can be operated selectively using a simple operation without using plural levers. A base bracket of the seat device is fixed to a lower arm. The base bracket has a stopper and pivotally supports the first link member and the second member in a freely turning way. An upper arm has a contact portion.

In the case that the seatback is turned to the flat condition, the intervening member is moved towards the outside portion of the locus of movement of the contact portion. Consequently, the contact portion of the upper arm can be turned down on a large scale without getting in contact with the intervening member.
