Title: Lifter device
Inventor: KAJINO YUSUKE
IPC: F16D13/52
Filed: 2019-06-21
Abstract: To prevent sliding rotation during push-down operation and to securely lock the rotation when in the neutral position without increasing the operating load for lifting an operation handle.SOLUTION: A lifter device 10 comprises a support member S that supports an output shaft 22, an input member N that is coupled to an operation handle, a feed part A that transmits the rotation of the input member N to the output shaft 22, a lock part that rotationally locks the output shaft 22 relatively to the support member S and a friction generating part that applies a frictional force to the rotation of the output shaft 22. The friction generating part generates friction by pushing a clutch part 57a in the radial direction by the rotation of an inner lever 53 forming the input member N so that a leaf spring is pressed onto a rotating plate integrated with the output shaft 22. The inner lever 53 realizes a friction-suppressed state where it does not push the clutch part 57a in the radial direction even when the operation handle is at a neutral position or the operation handle is turned from the neutral position to upper side, whereas the inner lever realizes a friction-on state P2 where it pushes the clutch part 57a in the radial direction when the operation handle is turned from the neutral position to lower side.SELECTED DRAWING: Figure 18
