The invention provides an opening / closing member driving device and a toilet lid opening / closing unit. Even if a load generating mechanism is provided for holding an opening / closing member at a predetermined rotation angle position around the axis of an output shaft, the rigidity of the output shaft can be prevented from being reduced. The opening / closing member driving device is provided with a load generation mechanism (73) that applies a load to the output shaft (7) when the output shaft (7) passes through a predetermined rotational angle position. The load generation mechanism includes: a first rod-shaped member (39) inserted into a cut groove (19a) formed in a cylindrical portion (19) of the housing located on the outer peripheral side of the output shaft; an elastic member that comes into contact with the first rod-shaped member from the outside of the cylindrical portion and that projects the first rod-shaped member from the cylindrical portion to the inside in the radial direction; and a protrusion (47) protruding radially outward from a first shaft portion (41) of the output shaft, the first shaft portion being located radially inward of the cylinderical portion. Therefore, the load generation mechanism is arranged on the outer side of the output shaft, so that the rigidity of the output shaft can be prevented from being reduced.
Description
technical field [0001] The present invention relates to an opening and closing member driving device for driving an opening and closing member, and a toilet lid opening and closing unit for opening and closing a toilet lid of a toilet unit as an opening and closing member. Background technique [0002] Patent Document 1 describes an opening and closing member drive device that opens and closes an opening and closing member such as a toilet lid. The opening and closing member driving device of Patent Document 1 includes: an electric motor; an output shaft; a transmission mechanism for transmitting the driving force of the electric motor to the output shaft; and a case for accommodating the electric motor and the transmission mechanism. The output shaft includes: a protrusion protruding outward from an opening provided in the housing; and a base located inside the housing. The opening and closing member is connected to the protrusion. A gear portion receiving a driving force...
