To provide an unlocking device and a vehicle seat designed such that a lever can easily be swung from the side of a seat or from the rear of the seat and lever operability is improved.SOLUTION: A first lever 21a and a second lever 21b are supported by a support member 17, attached to an upper part of a seat back 5, so as to be swingable in a seat longitudinal direction around a first swing shaft 19a and a second swing shaft 19b, respectively. The first lever 21a has a first swing operation portion 39a at a rear end thereof, and the second lever 21b has a second swing operation portion 39b at a front end thereof. The link 23 includes a first to-be-engaged portion 39a that can be engaged with and disengaged from a first engaging pin 45a of the first lever 21a, and a second to-be-engaged portion 39a that can be engaged with and disengaged from a second engaging pin 45b of the second lever 21b. When the first lever 21a or the second lever 21b swings upward, a wire 25 is pulled via the link 23, and a lock device 13 that restricts tilting of the seat back 5 with respect to a seat cushion 3 is unlocked.SELECTED DRAWING: Figure 2
