Abstract
An operation device includes a rotatable operation panel and a tilt mechanism including a recessed groove and pawl member capable of engaging with the recessed groove and an urging member configured to elastically urge the pawl member. In the engaging state, the pawl member contacts with the recessed groove at a first position and a second position. A relationship 0°<θ<90° is satisfied, where, in cross-section orthogonal to the rotation axis, an angle θis defined between: a first imaginary line connecting the first position and a rotation axis; and a second imaginary line along an inclined surface of the first position side in the recessed groove, and an angle θis defined between: a third imaginary line connecting the second position and the rotation axis; and a fourth imaginary line along an inclined surface of the second position side in the recessed groove.
