The invention relates to an improved pedal structure which comprises a pedal body and an axis body, the pedal body is provided with an axis hole, at least one bearing piece is arranged in the axis hole, and the bearing piece located at the tail end of the pedal body and the tail end of the axis body is a ball bearing. The axle center body comprises a locking end with a larger diameter and a pivoting end with a smaller diameter, the pivoting end is accommodated in the pedal body, the tail end of the pivoting end is a small thread section for a fixed nut to be locked and propped against an inner lantern ring of the ball bearing, so that the pedal body and the axle center body are locked and positioned, and the outer lantern ring of the ball bearing is locked and positioned through an axle center hole sleeve cover. The pedal is mainly characterized in that a convex abutting edge with a larger diameter is integrally formed on one side of the fixing nut, so that the convex abutting edge can just abut against an inner lantern ring of the ball bearing with a larger area, and the assembly process of the pedal body and the axis body can be simpler and more convenient by means of the design of the convex abutting edge integrally formed on the fixing nut; and moreover, the uncertainty that the traditional gasket is easy to generate uneven abutting is completely avoided, so that the effects of simplifying the structure and improving the assembly stability of the structure are achieved.
本发明是一种踏板改良结构,其包括一踏板本体及一轴心体,该踏板本体设有一轴心孔,该轴心孔内设有至少一轴承件,其中位于踏板本体与轴心体末端的轴承件为一滚珠轴承,而该轴心体包括较大径的锁接端与较小径容置于踏板本体内的枢接端,该枢接端末端为一小段螺牙段供一固定螺帽锁抵在滚珠轴承的内套环上,以将踏板本体与轴心体锁固定位,滚珠轴承的外套环则藉由一轴心孔套盖锁固定位,其主要特征在于该固定螺帽一侧一体成型出具较大径的凸抵缘,使该凸抵缘恰可以较大的面积抵接于该滚珠轴承的内套环上,藉由该固定螺帽一体成型的凸抵缘设计可使踏板本体与轴心体的组装工序更为简单便利,而且完全不会有传统垫片容易产生不平整抵接的不确定性,以达到简化结构及提升结构组装稳定性的功效者。
