Imaging apparatus having a biasing part configured to generate a biasing force to bias a part of the image pickup device

The magnitude of magnetic attraction generated between an electromagnetic coil and a magnetic metal member (or an amount of electric current flowed to the electromagnetic coil) is controlled depending on a direction of acceleration (acceleration caused by the gravity (a gravitational acceleration) and acceleration caused by shake (shake acceleration)) working on an imaging apparatus. This magnetic attraction moves a second slider (including a CCD and a first slider) as a whole toward the electromagnetic coil. This movement brings two inclined surfaces (or fourth and fifth surfaces) of a shaft hole 10d into contact with a second guide shaft with no gap being interposed in between, and keeps the this contact condition.
