Micro-adjustable belt structure
 A micro-adjustable belt structure including a belt head, a micro-adjusting strap, a micro-adjuster and a clip buckle. The micro-adjuster is formed with a dent in which a magnet is fixedly disposed. The clip buckle is also formed with a dent in which a magnetic member such as an iron plate is fixedly disposed corresponding to the magnet. The clip buckle is made of a non-magnetic material. The magnetic member is covered by a protective film for protecting the magnetic member from being rusted. The magnet and the magnetic member attract each other to attach the micro-adjuster and the clip buckle to each other.
