PROBLEM TO BE SOLVED: To provide a bouncer that enables adjustment of an inclination angle of a sheet frame unit to be simply performed.SOLUTION: A seat frame unit 40 for assembling a seat has a turning shaft 42 pivotally supported to a base unit 20, and an inclination angle &thetas; is adjusted by an angle adjustment mechanism 60. The angle adjustment mechanism includes a U-shaped seat side adjusting unit 43 with a horizontal rod 46 connected to a turning shaft, and an angle adjuster 61 turnably supported to a support shaft 35 of the base unit and capable of adjusting an inclination angle by storing a horizontal rod to a predetermined storing groove 70. The angle adjuster is a circular body provided with an opening part 66 for movement capable of moving the horizontal rod, and is configured by providing biasing means 85 for forward biasing of an upper end 61a side. The opening part for movement includes a tip recess 68 capable of storing the horizontal rod on the tip, and a root side recess 67 capable of storing the horizontal rod when folding the seat frame unit so as to be stacked in the base unit.SELECTED DRAWING: Figure 6 |
