Patent ID: 7798539

Claim:
An opening mechanism of a door lock device for a vehicle, comprising: an active lever operable to selectively establish a locked position where a latched state between a latching means provided at a body of the vehicle and a latched means provided at a door is unreleasable and an unlocked position where the latched state between the latching means and the latched means is releasable; an open lever operably connected to a handle and operating in response to an operation of the handle; an open link operably connected to the open lever and the active lever, the open link allowing a transmission of an operational force of the open lever to the latched means when the active lever is at the unlocked position and disabling a transmission of the operational force of the open lever to the latched means when the active lever is at the locked position, the open link including a first side surface and a recess portion; a lift lever which operates in response to the operation of the open link based on the operation of the handle when the active lever is at the unlocked position to release the latched state of the latched means; and a cancel lever changing a state of the open link from a locked state to an unlocked state by affecting the open link by an operational force from the latched means, the cancel lever having a first contact end portion that is biased by biasing means to contact the first side surface of the open link in a closed state of the handle, having the cancel lever in the moving path of the lift lever and biased to contact the recess portion in an opening state of the handle so that the cancel lever is moved away from the moving path of the lift lever; wherein the active lever comprises an elongated bore; the open link comprises an engaging portion which engages with the elongated bore to be slidable therein so that the opening mechanism can be downsized compared to an opening mechanism in which the open link comprises the elongated bore; and the elongated bore and the engaging portion are engaged to engage the active lever and the open link.
