An anti-loosening structure is applied to a lock mounting plate of a door lock mechanism and a fixing member. The lock mounting plate includes an axial hole and at least one assembling hole having a fastener portion on a periphery thereof. Correspondingly, the fixing member includes a head portion, a shank portion and a detent portion formed on the head portion proximate to the shank portion. The fastener portion of the lock mounting plate is connected with the detent portion of the fixing member such that the engagement of the fixing member with the lock mounting plate is insured when the fixing member mounts the lock mounting plate to a door plank.
