Abstract
An output shaft, to which the rotational force of a motor is transmitted, is rotatably supported and housed in a case. One end of the output shaft protrudes from the case, and a pinion gear is provided on this one end. Teeth that mesh with the pinion gear are provided on the outer circumferential surface of cables. A guide member for guiding the cables in such a way that they mesh with the pinion gear is mounted on the case. An urging plate portion that presses against the side of the pinion gear is provided on the guide member. The urging plate portion urges the output shaft in the axial direction and, as a result, rattle of the output shaft is alleviated.
Claims6
A drive device for driving an object to be driven with a drive cable by using the rotational force of a motor to move the cable, the drive device comprising:
- an output shaft to which the rotational force of said motor is transmitted;
- a case in which said output shaft is rotatably supported and housed with one end protruding and;
- a drive-side meshing part provided on said one end of the output shaft;
- a driven-side meshing part provided along a predetermined length of said cable;
- and
- a guide member for guiding said cable in such a way that said driven-side meshing part meshes with said aforementioned drive-side meshing part,
- wherein an urging part for urging said output shaft in the axial direction is integrally formed in said guide member;
- and
- wherein the urging part of the guide member is formed in the shape of a plate spring and is disposed between the outer surface of the case and the drive-side meshing part.
