PROBLEM TO BE SOLVED: To provide a vehicle seat frame capable of demonstrating excellent cushioning property by elongation of a shock-absorbing device 17, omitting a link for vertical operation, simplifying the configuration, supporting the load on mounting portion of a seat frame 3 and the shock-absorbing device 17 by a front side upper mounting shaft 13 and a front side lower mounting shaft 31. SOLUTION: Right and left front side portions of a seat frame 3 of a seat 2 are rotatably mounted on a front side portion of a base frame 11 fixed to a vehicle body or mounted movably in an arbitrary direction by the front side upper mounting shaft 13, and a rear portion of the seat frame 3 is vertically moved around the front side upper mounting shaft 13. An upper portion of the shock-absorbing device 17 mounted on the base frame 11 is mounted on right and left rear sides of the seat frame 3 by the front side lower mounting shaft 31. The shock-absorbing device 17 comprises a damping viscous damper 18 formed of viscous fluid or viscous elastic body D having the nature that the viscosity is increased proportional to the moving speed, and a compression spring 19 to support the load. The front side upper mounting shaft 13 and the front side lower mounting shaft 31 are connected and fixed to each other at other portions than the mounting portion on the base frame 11 in the vehicle seat frame.
