An open-and-close structure 1A for a cap includes a housing 2, a cap 3 rotatably supported on the housing 2, and a biasing member 43 configured to apply a biasing force near a rotation shaft 42 of the cap 3, wherein open position-maintaining means configured to maintain the cap 3 at an open position by a biasing force of the biasing member 43 and reaction force application means configured to apply a reaction force in a closing direction by the biasing member 43 to the cap 3 in response to a further movement of the cap 3 in an open direction from the open position are provided on at least one of a support portion 32 that is a cap-side sliding contact portion or a sliding contact member 45 that is a biasing member-side sliding contact portion.

A hinge assembly for a trunk lid, includes: a hinge bracket attached to a trunk compartment; a hinge arm attached to a trunk lid and pivotally connected to the hinge bracket; and a damping mechanism disposed between the hinge bracket and the hinge arm, and damping a pivoting movement of the hinge arm, where the hinge arm has a hollow portion in which the damping mechanism is received.

An open-and-close structure 1A for a cap includes a housing 2, a cap 3 rotatably supported on the housing 2, and a biasing member 43 configured to apply a biasing force near a rotation shaft 42 of the cap 3, wherein open position-maintaining means configured to maintain the cap 3 at an open position by a biasing force of the biasing member 43 and reaction force application means configured to apply a reaction force in a closing direction by the biasing member 43 to the cap 3 in response to a further movement of the cap 3 in an open direction from the open position are provided on at least one of a support portion 32 that is a cap-side sliding contact portion or a sliding contact member 45 that is a biasing member-side sliding contact portion.

A multi-position door hinge is coupled to a vehicle and includes a first hinge having a pin support, a pin, and a key. The multi-position door hinge additionally includes a second hinge having a receiving cam, a key way, and a cam groove. The multi-position door hinge is formed by coupling the first hinge to the second hinge by positioning the pin in the receiving cam with the key positioned in the key way.

An assembly may include a body side bracket configured to be mounted to a body of a motor vehicle. The assembly may include a hinge arm rotatably mounted to the body side bracket, wherein the hinge arm is rotatable between a closed position and a fully open position. The assembly may further include a detent arm rotatably mounted to the body side bracket. Further, the assembly may include a cam mounted to the hinge arm and configured to travel along the detent arm with movement of the hinge arm. The cam and detent arm are configured to stop and hold the hinge arm in at least one intermediate position between the closed position and the fully open position.

A door checker for a vehicle includes a hinge rotatably connecting a door to a vehicle body and having a shaft, a slider penetratingly inserted into the shaft and linearly moving with rotational force of the shaft, and a checking unit linearly reciprocating in a radial direction of the shaft by the slider. By implementing a manipulation feeling in opening and closing a door by increasing a section for checking the door by converting a rotational movement of the door into a linear movement based on a screw principle, operability can be improved to enhance marketability, and durability can be enhanced by increasing the section for implementing operating force for opening and closing a door.
