Abstract
A parking brake apparatus includes a rotating unit which is rotated around a rotating axis. A position detecting unit has a switch part which is movable in a direction of the detecting unit between a first position and a second position, the position detecting unit detecting a position of the rotating unit based upon a movement of the switch part. A pressing unit provided on the rotating unit moves the switch part in the direction, the pressing unit and the rotating unit being rotated together around the rotating axis when the rotating unit is rotated. The pressing unit moves the switch part by connection of the pressing unit with the switch part at a contact point when the rotating unit is rotated from a release position to a position exceeding the release position. The pressing unit and the switch part are arranged such that a distance between the contact point and the rotating axis is maintained below a reference distance.
