Abstract
According to one embodiment, a vibration damping apparatus for an elevator car includes an engaging apparatus, an interlocking mechanism, and a friction generation mechanism. The engaging apparatus includes a pair of engaging vanes. A gap between the vanes is narrowed when the car door apparatus is opened. The interlocking mechanism includes a lock lever and an engaging body, is released by an action of the engaging vanes holding the engaging body, and interlocks the hall door apparatus with operation of the car door apparatus. The friction generation mechanism generates a frictional force between the engaging vanes and the engaging body for suppressing a vertical vibration of the car when the engaging vanes are in a state of holding the engaging body.
