A coil spring 69 compressed in a direction along the check link 24 is interposed between the large flange portion 73 and the base plate 70 and urges the slider 75 to protrude. The large flange portion 73 receives a pressing force from the coil spring 69, and the small flange portion 74 presses the contact plate 53 of the contact unit 42 through a boot 76 described later. A boot 76 is attached so as to cover the slider 75 and the coil spring 69. The slider 75 is restricted from protruding by a protrusion restricting means (not shown). In FIG. 2, the boot 76 is in a compressed state.

Next, the operation of the above embodiment will be described.
When the side door 3 is opened, the check link 24 attached to the vehicle body 1 side is relatively pulled out from the side door 3. When the first notch 38 of the covering portion 37 of the check link 24 that is relatively pulled out from the side door 3 reaches the position of the shoe main body 65, the side door 3 is maintained open with a sense of moderation. When the side door 3 is further opened and the second notch 40 of the covering portion 37 of the check link 24 reaches the position of the shoe main body 65, the side door 3 is fully opened and held at that position. Thereafter, when the side door 3 is further opened, the stopper member 41 elastically contacts the shoe main body 65 without shock, and further opening operation of the side door 3 is restricted.

On the other hand, when the side door 3 is closed from this state, the check link 24 is relatively inserted into the side door 3 and the side door 3 closes the door attachment opening 2.
The contact plate 53 of the contact unit 42 on the side door 3 side of the check link 24 immediately before the closing position of the side door 3 contacts the small flange portion 74 of the slider 75 of the elastic unit 7 through the boot 76, Further, the contact plate 53 presses the small flange portion 74 of the slider 75 of the elastic unit 7 through the boot 76 by the side door 3 that is closed, and the slider 75 is retracted while compressing and deforming the coil spring 69 of the elastic unit 7. . Thereby, the latch R of the side door 3 is engaged with the striker S provided in the vehicle body 1, and the side door 3 is closed as shown in FIG.

  Therefore, since the check link 24 is biased in the opening direction by the coil spring 69 of the compressed elastic unit 7 with the side door 3 closed, the door knob H is opened when the side door 3 is opened. When the engagement between the latch R and the striker S is released by operation, the compressed coil spring 69 is extended by elastic force, so that the small flange portion 74 of the elastic unit 7 is brought into contact with the contact plate 53 of the contact unit 42. To push the check link 24 out of the side door 3. Thereby, the side door 3 can be opened slightly.

According to the above embodiment, when the side door 3 is opened from the state in which the side door 3 is closed, the side door 3 is opened by the coil spring 69 of the elastic unit 7 via the check link 24 in the closed state of the side door 3. Since the force is applied in the operation direction, the operation in the opening direction at the initial stage of the opening operation of the side door 3 can be facilitated. Therefore, even when the hand is occupied, the side door 3 is slightly opened by the coil spring 69 when the engagement between the latch R of the side door 3 and the striker S of the vehicle body 1 is released, so that the hand may think. Even if it cannot be used, the opening operation of the side door 3 can be easily performed. Even when the present invention is applied to a vehicle 1 in which the door knob H is not provided, the side door 3 can be slightly opened by the biasing force of the coil spring 69 at the initial opening of the side door 3, so that there is no door knob. This is suitable for a vehicle in which the side door 3 is opened using a wireless key.
Further, the arrangement position of the elastic unit 7 in which the side door 3 is opened can be easily set only by making the compression direction of the coil spring 69 of the elastic unit 7 coincide with the arrangement direction of the check link 24. Application to is easy.

Further, since the check link 24 receives a force in the compression direction from the coil spring 69 of the elastic unit 7 and can be prevented from receiving a force in the bending direction, it is advantageous in terms of strength and rigidity of the check link 24.
The force acting in the direction in which the side door 3 is pulled away from the vehicle body 1 by the coil spring 69 of the elastic unit 7 is used to connect the vehicle body 1 and the side door 3 to the upper hinge bracket 4 and the lower hinge bracket 5. Since it can support reliably by the upper hinge bracket 4, it is advantageous on the vehicle body support rigidity of the side door 3. FIG.

  The invention described in claim 1 is not limited to the above-described embodiment, and is provided along with the door checker 6 so as to follow the locus of the opening direction of the side door 3 on the side of the rotating end of the side door 3. However, when the elastic unit 7 is provided in the vicinity of the upper hinge bracket 4, the extension amount of the coil spring 69 of the elastic unit 7 is included. Since the side door 3 can be opened sufficiently even if there is little, there is an advantage that the elastic unit 7 can be downsized.
