Abstract: The present invention relates to the field of toys, and more specifically, to a magnet-mounted part for mounting a magnet and a magnet toy. Particularly, the present invention provides a magnet-mounted part comprising: a magnet mounting unit on which a magnet is mounted, and which has a saw-toothed wheel engaged with the magnet-mounted part on which an external magnet is mounted, an accommodation unit which accommodates the magnet-mounted unit therein, and has an opening portion such that the saw-toothed wheel of the magnet-mounted unit can be exposed; and a One rotation angle-adjusting unit which is provided to rotate in engagement with the magnet-mounted unit and the accommodation unit, and is formed such that the unit rotation intervals thereof are smaller than the toothed intervals of the saw-toothed wheel of the magnet-mounted unit.

Abstract: The present invention relates to a sawtooth structure in which an external sawtooth structure and an internal sawtooth structure engage with each other to support a fine joint angle adjustment function, and to a toy block-comprising such structure. A sawtooth structure of the present invention comprises an external sawtooth structure and an internal sawtooth structure, wherein the external sawtooth structure has an inner surface with one or more areas on which an inner sawtooth portion of the external sawtooth structure containing at least two or more inner sawteeth of the external sawtooth structure is formed, and the internal sawtooth structure has an outer surface with one or more areas on which an outer sawtooth portion of the internal sawtooth structure that corresponds to the inner sawtooth portion of the external sawtooth structure and that contains at least two or more outer sawteeth of the internal sawtooth structure is formed.
