Conventional tear inducing ribs are replaced with pockets so that a contact area is increased so as to stably induce a tear of a scoring line. According to the present invention, a tear inducing apparatus for a passenger airbag (PAB) door includes a scoring line disposed on the PAB door and configured to be opened when an airbag cushion deploys, and a plurality of tear inducing pockets disposed on both sides of the scoring line to face each other and arranged in a longitudinal direction of the scoring line. Each of the plurality of pockets includes an empty inner space and a ridge including a flat portion positioned toward the airbag cushion.
