  "textContent": "A seat lifter device includes: an output shaft; a support unit that supports the output shaft; an input unit; a ratchet-type feed unit configured to transmit rotation of the input unit to the output shaft; a lock unit configured to lock rotation of the output shaft relative to the support unit; a friction generation unit configured to apply a friction force between a rotation member and the support unit in response to an operation of the input unit rotating in a direction in which the seat is lowered; and a slippage preventing unit. When the input unit rotates in the direction in which the seat is lowered and the output shaft rotates preceding to the feed unit against the friction force to slip, the slippage preventing unit is fitted to the support unit by an elastic force in response to slippage of the output shaft to stop the slippage.",
