Two stubs project from a side of the follower. A spring is mounted around each stub and has an end attached to the fixing plate. A first outer plate and a second outer plate are secured together, sandwich the box, and are pivotable relative to the box. A pivot pin is pivotally mounted in the vertical space of the box. A mediate portion of the pivot pin includes two opposite flat surfaces and two opposite arcuate surfaces. A gasket is securely sandwiched between the first outer plate and the second outer plate to move therewith. The gasket includes a portion for securely engage with an edge of a frameless glass door. The first side of the follower is pressed against by one of the flat surfaces and the arcuate surfaces of the mediate portion of the pivot pin during pivotal movement of the glass door relative to the box. |
