<P>PROBLEM TO BE SOLVED: To suppress generation of abrasion powder without adding a special component even when the frequency of release increases. <P>SOLUTION: An imaging apparatus provided with a mirror unit turnable between a finder observation position and a light exposure retreat position includes: a first mirror for guiding an imaging light flux to a finder optical system when the mirror unit is located at the finder observation position; a first holding member for holding the first mirror; a second mirror arranged to be turnable with respect to the first mirror and guiding a transmitted light flux from the first mirror to a focus detector at the finder observation position; and a second holding member for holding the second mirror. The first holding member has: a first region not abutted with the second holding member on a side opposite to a surface holding the first mirror when the mirror unit is located at the light exposure retreat position; and a second region abutted with the second holding member and having a surface which is flatter than the surface of the first region. <P>COPYRIGHT: (C)2012,JPO&INPIT |
