<P>PROBLEM TO BE SOLVED: To provide a drive device capable of surely suppressing the dispersion in drive characteristics of a driven member. <P>SOLUTION: In the drive device 1, a drive member 14 is sandwiched by slide members 16C, 16D. By biasing the slide member 16C to the slide member 16D side by a biasing member 16B under the sandwiched state, the driven member 16 is made to engage with the drive member 14 by friction. Then, the slide member 16C is in a surface contact with the drive member 14 on two slide planes formed on the drive member 14. Accordingly, compared with a case where curved surfaces come into a surface contact with each other, the surface contact between the slide member 16C and the drive member 14 is ensured and the attitude of the slide member 16C to the drive member 14 is stabilized. Thereby, a friction force which occurs between the slide member 16C and the drive member 14 is stabilized, so that dispersion in drive characteristics of the driven member 16 can surely be suppressed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
