At the 'caused to require a precise manufacturing process = material to produce the outer sleeve of the transmission η and the sleeve member 12, if the outer diameter of the (five) 12 is too large, it is not easy to rotate the inner part, if the sleeve member The heart is too small I; I::::,——, [New content] Therefore, the purpose of the present invention is to simplify and assemble the one-way pulley with the function of transmission and sound reading. M351795 Thus, the novel one-way pulley can be wound around a transmission belt, and the one-way pulley comprises a transmission member, an input shaft, a plurality of elastic members, a plurality of pressing members, two gaskets, and two bearings. . The transmission member is a hollow tube body and has an outer peripheral surface, and an inner circumferential surface s is circumferentially opened into a plurality of sleeve grooves, so that the transmission belt can be fitted on the sleeve groove, the inner circumference The surface is formed with an inner convex ring defining a shaft hole and having an inner annular surface. The inner annular surface forms a plurality of spaced apart accommodating grooves. The input shaft is pivotally disposed in the shaft hole of the transmission member, and has an outer shaft surface and an inner shaft surface. Each elastic member is correspondingly placed in the corresponding receiving groove, and each pressing member also corresponds to The elastic member is placed in the corresponding accommodating groove and abuts against the elastic member in the accommodating groove, so that the elastic member can be forced to push the corresponding pressing member without being subjected to external force or external force. The pressing member portion is protruded from the shaft hole. The cymbals are placed in the transmission member and respectively blocked on both sides of the inner convex garment, the mother shims having a first surface facing the inner convex ring and opposite to the first surface of the cymbal In the second side, the bearings are embedded in the transmission member and respectively contact the second surface of the corresponding gasket. The effect of the present invention is that the member of the one-way pulley can be reduced by the inner convex ring of the integrally formed transmission member, and the assembly work of the one-way pulley can be effectively simplified. [Embodiment] The foregoing and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the drawings. 2 to 4', the novel one-way pulley 2 can be used for a transmission belt 1: a winding belt 2, which includes a transmission member 3, an input shaft 4, a plurality of elastic members 5, and a plurality of forced Pressing member 6, two washers 7, two bearings 8, - C-type buckle % 9 ' and two dust cover 91. - The transmission member 3 is a hollow tube body having an outer peripheral surface 3b and a peripheral surface 32. The outer circumference; the outer peripheral surface 31 of the X forms a plurality of sleeve grooves 33, so that the transmission (10) can be fitted to the On the sleeve groove 33, the inner peripheral surface 32 is formed with a garment 32 丨'. The inner convex ring 321 defines a shaft hole 322 and has an inner annular surface 323 ° continuation surface 323 to form a plurality of spaced arrangements. Slot 324. The present inner ring surface 323 has three accommodating grooves 324. Each of the 0 elastic members 5 is placed in the corresponding receiving groove 324 +, and each of the pressing members 6 is placed in the corresponding receiving groove and is received by the elastic member 5 in the receiving groove 2. When the (four) member 5 is unaffected by external force or loss, each of the elastic members 5 can push the corresponding member (4) 6 so that it protrudes from the shaft hole 322. In the present embodiment, the one-way pulley elastic member 5 and the three pressing members 6 are correspondingly disposed in the aforementioned receiving grooves 324. The slats 7 are placed in the transmission member 3 and are respectively stopped on both sides of the inner jewel 321 , and each of the shims 7 has a first face 7 facing the inner convex ring 32 and Contrary to the second face 72 of the first face 71. The slats 7 can be positioned in the accommodating grooves, such that the elastic members 5 and the urging members 6 are not separated from the accommodating grooves. The bearings 8 are embedded in the transmission member 3 and are placed in contact with the two sides 72 of the cymbal '7 M351795. The inner circumference φ 32 of the transmission member 3 forms two recesses 325 and is respectively located on both sides of the inner convex ring 321 . Each of the grooved milks is provided with a c-shaped clasp 9 = partially protruded therefrom. In addition to the circumferential surface 32, in order to assist in positioning the drawers 8 in the transmission member 3, the dust caps 91 cover the bearings 8 to prevent dust from contaminating the bearings 8.

Each elastic member 5 is fitted with a pressing member 6 corresponding thereto. In the accommodating groove 324, the elastic member 5 urges the pressing member 6 when the external force or the external force is not lost, so that the pressing member 6 partially protrudes from the valley groove 324 and abuts against the input shaft. 4 outer shaft surface 41, when the shaft 4 is rotated in the correct direction, the outer shaft surface 41 of the wheel shaft 4 will be pushed against the "equal pressing member 6" to cause the pressing members 6 to abut the same The inner wall ' of the accommodating groove 324 further drives the transmission member 3 to rotate. If the input shaft 4 rotates in the opposite direction, that is, the direction indicated by the arrow in FIG. 5, the input shaft 4 outer shaft surface 41 pushes the pressing force. The member 6 further presses the elastic members 5 to move the pressing members 6 to the positions of the imaginary lines as shown in FIG. 5 and retreat into the accommodating grooves 324, causing the input shaft 4 to idle and no longer The transmission member 3 is driven to rotate, and the transmission member 3 is controlled to rotate in a single direction by the above structure. As can be seen from the above description, the transmission member 3 and the inner convex ring 321 are integrally formed. It can effectively save the assembly time and cost, and provide a one-way pulley with simple components, convenient assembly and reliable transmission, so it can achieve the effect of this new type. 9 M3 51795 Quasi-above, only the preferred implementation of this model For example, it is possible to limit the scope of the implementation of the present invention, that is, the simple equivalent changes and modifications made by the novel according to the novel: = and the new description are still within the scope of the novel patent.
