• an upper case (300) which has a through opening through which a strut is configured to pass;
• a lower case (400) which is relatively rotatably coupled to the upper case (300) and has a through opening through which the strut is configured to pass, wherein a coil spring is installed on an outer circumferential surface of the lower case (400);
• and
• a center plate (500) which is disposed between the upper case (300) and the lower case (400) and rotatably supports the upper case (300) relative to the lower case (400),
• wherein the center plate (500) has a through opening through which the strut is configured to pass and comprises a cylindrical vertical portion (510) which extends axially from a radial inner side, an inclination portion (520) which is formed to be inclined downward radially outward from the vertical portion (510), and a horizontal portion (530) which extends radially outward from the inclination portion (520), and
• wherein the inclination portion (520) and the horizontal portion (530), respectively, comprise a first contact portion (521) and a second contact portion (531) that are formed to protrude to come into contact with the upper case (300), respectively.
