A seat lifter structure which can obtain a rotation of a sector with stable torques is provided. It is equipped with a sector (7) supported to be rotatable by a support member (21), arranged to be facing with a side frame (2) by being pinched and fixed by a pair of expanded portions (6a, 6b) of a tubular shaft member (6) that is supported to be rotatable by the side frame (2), and rotating along the side frame (2) at a time of raising or lowering the side frame (2); a ring shaped spacer (13) having a first ring shaped abutting surface (13da) facing with the sector (7) and having a first outer diameter (ϕ13d2), and a second ring shaped abutting surface (13ca) facing with the side frame (2) and having a second outer diameter (ϕ13c2) different from the first outer diameter (ϕ13d2), which is installed between the sector (7) and the side frame (2) with an axial line (CL6) as a center; and a biasing member (12) that biases and abuts the sector (7) to the first abutting surface (13da) and biases and abuts the side frame (2) to the second abutting surface (13ca) by biasing the sector (7) and the side frame (2) to approach.
