A structure of steplessly adjusting angle for a cymbal of the invention includes an upper rod for screwing a cymbal on its top, and a lower rod that is pivotally connected to the upper rod. Also, an appended portion is provided at one side of the head of the lower rod, and a bearing body can be inserted into the center of the appended portion so that the upper rod and the lower rod can be united. Besides, a clamping head designed to have two corresponding clamping portions is provided on the bottom of the upper rod. Also, a clamping slot is provided at top of the clamping head in the axial direction, and the clamping slot is bent laterally outwards to form an opening. The central hole of the clamping head is sleeved onto the appended portion of the lower rod so that the components ready to be combined horizontally can be united. Thus, the upper rod can achieve an effect of stepless angle fine-tuning, and the operation of spanner twisting will not be limited by the space.
