<p>PROBLEM TO BE SOLVED: To provide a seat lifter device for vehicle equipped with a rotation control device which has simple constitution and can be made compact.SOLUTION: A rotation control device 21 includes a ratchet wheel 30 which shares a rotary shaft 22 with a pinion gear and rotates in one body, and an operation member which rotates at a coaxial position with the ratchet wheel 30 based upon rotating operation on an operation handle. Further, the rotation control device includes a first lock lever 41 and a second lever 42 which engage the ratchet wheel 30 to restrict rotation of the pinion gear in a direction of upward movement and a direction of downward movement of a sheet. Further, the rotation control device includes a drive lever 43 which rotates integrally with the operation member in the state of engagement with the ratchet wheel 30 to drive and rotate the pinion gear in the direction of the upward movement of the sheet. Then the rotation control device includes a plurality of control pieces (61-63) which disengage the respective lever members (41-43) from the ratchet wheel 30.</p> |
