ABSTRACT:
A small braking apparatus, which is able to completely and suddenly stop a moving portion such as a linear direct current motor at a desired location, is described, together with a drive unit equipped with the braking apparatus. The braking effect is obtained by providing a rotary member on a slider to move along a long guiding member, and providing a driving device which causes a braking member, which performs a braking action by engaging with said rotary member, to engage and move away from said rotary member.
