Door lock device for vehicle

Abstract

A door lock device for a vehicle includes an operating mechanism (B) being selectable of a locked state where a latched state, between a latching means (50) and a latched means (44, 45, being unreleasable and an unlocked state where the latched state being releasable, an active lever (24) being rotatable between a locked position and an unlocked position thereof, an open link (26) disabling a transmission of an operational force of a handle to the latched means under the locked state and allowing a transmission of the operational force of the handle to the latched means under the unlocked state, characterized in that the active lever, provided with an elongated bore (24d2), is supported by a housing which houses the operating mechanism to be rotatable, and the open link is operatively connected to the handle to be slidably supported by the housing and is provided with an engaging portion (26b) which engages with the elongated bore to be slidable therein.

Description

technical field [0001] The invention relates to a door lock device for a vehicle. Background technique [0002] JP2001-262903A (see paragraph 0024-0027, figure 1 ) The existing door lock device for vehicles described in includes an operating mechanism that selectively realizes the locked state and the unlocked state, wherein, in the locked state, the latch device (ie, the striker 45) provided on the vehicle body and the The latched state between the locked devices of the door (that is, the lock piece 41 and the pawl 42, etc.) cannot be released, while in the unlocked state, the latched state is releasable. [0003] With the structure of this existing door lock device, the locked state in which the latch state between the lock piece and the striker cannot be released can be realized by operating the lock button in the vehicle, and the locked state or unlocked state of the door lock device can be achieved by The lock cylinder is operated by turning the key blade outside th...

Problems solved by technology

Therefore, the size of the case housing the operating mechanism of the door lock increases, a larger space is required to install the door lock device, and the cost of components increases due to the increase in size.

[0006] According to another aspect, the existing door lock device for vehicles described in JP2001-262903A has the following disadvantages: There is a gap between the engagement pin 22b and the first engagement groove 23a in the structure in which the pin 22b is connected to the release lever 22 and the opening link 23, so when the release lever 22 and the opening link 23 are operated, since the engagement pin 22b and the first engagement Noise due to vibration between slots 23a

This increases the size of the opening link 23, which results in an increase in the size and cost of the door lock device for the vehicle.
