Title:
SEAT DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2018192889
Kind Code:
A
Abstract:
To enable a connection cylindrical body to stably move relative to an output shaft in an axial direction even in a state where rotational force is applied between the connection cylinder body and the output shaft of a clutch mechanism when connection of the clutch mechanism is released.SOLUTION: A clutch mechanism includes: a connection cylindrical body 460 configured to connect with a driving shaft from an axial direction or release the connection; and an output shaft 470 which is coaxially inserted into the connection cylindrical body 460 and connected with a position adjustment mechanism of a vehicle seat. Projections 473t extending in the axial direction are formed on an outer peripheral surface of the output shaft 470 of the clutch mechanism. Flat surfaces 460f with which the projections 473t respectively contact from a rotation direction are formed on an inner peripheral surface of the connection cylindrical body 460 of the clutch mechanism. The projections 473t and the flat surfaces 460t contact with each other from the rotation direction to hold the connection cylindrical body 460 and the output shaft 470 of the clutch mechanism so that the connection cylindrical body 460 and the output shaft 470 cannot rotate around an axis relative to each other and can move relative to each other in the axial direction.SELECTED DRAWING: Figure 13
