The sports equipment roller rim includes a bearing 11, a metal support tube 12, and an outer layer U. The bearings 11 are rotated relative to the pedal shaft 21, and an inner peripheral surface is mounted on the pedal shaft 21. The support tube 12 is sleeved on an outer peripheral surface of the bearings n. The outer cushion layer 13 has a covering portion 131 covering an outer peripheral surface of the supporting tube 12, and two protruding portions 132 extending radially outward from an outer peripheral surface of the covering portion 131, and the like. The projections 132 define two adjacent sides. The wheel supports 133 at the two ends of the 12th support, and the wheel 133 is limited to roll on the sliders 22. "Hai sports equipment roller 1 can drive the pedal shaft 2 运动 relative to the sliding rod 22, but there are still the following defects: First, if the outer cushion layer 13 is made of polyurethane (p〇lyurethane ' Referring to PU), when the sports equipment roller rim is continuously used for a period of time to increase the temperature, the outer cushion layer 13 may loosen the support tube 12, resulting in a lack of durability. 2. If the outer cushion layer 13 When the rubber having a soft texture is selected, the protrusions 132 have poor reading degree, so that the bending deformation of the armature 1 may be deviated from the sliders 22, resulting in poor finite position. 5 M310717 The absence of the first, right, the outer cushion layer 13 when the hard rubber or plastic material is used, the protrusions 132 (four) are not easy to form, and the vibration of the sports equipment 1 is increased. The comfort of the operation of the sports equipment 2 is reduced. [New content] Therefore, the object of the present invention is to provide a sports equipment roller which can improve durability, limit and comfort. Wheel is a plurality of bearings, a metal support tube, and a soft outer cushion layer. The bearings rotate relative to the sports equipment, and an inner peripheral surface is mounted on the sports equipment. The support tube includes _ sleeves disposed thereon The bearing-supporting cymbal on the outer peripheral surface, and a plurality of inner convex portions formed on an outer peripheral surface of the support portion, cover the outer peripheral surface of the support tube and are placed on the sports equipment. The function of the light wheel of the new sports equipment is that the outer cushion layer can improve the durability and comfort by the design of the inner convex portion, and can achieve a good limit function. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figures 2 and 3, a preferred embodiment of the novel sports equipment roller is adapted for mounting on the sports equipment 9, the sports equipment 9 having a pedal shaft M310717 91 and two slide bars 92. The sports equipment roller comprises two bearings 3, a metal support 4 and an outer cushion 5 made of soft rubber. The bearings 3 are rotated relative to the pedal shaft 91 and are opposite to the opposite ends of the support tube 4, and an inner peripheral surface is mounted on the pedal shaft 91. The cymbal support 4 includes a set of support portions 4 disposed on an outer peripheral surface of the bearings 3 and four inner ridges 42 formed on the outer peripheral surface of the undulation portion 41 and extending radially outward, wherein The inner convex portion 42 is adjacent to the branch portion

The outer layer 1 is wrapped on the outer peripheral surface of the support tube 4 and is slid on the sliding rod 92± of the sports equipment 9 and includes an outer connecting portion 51 ′ on the branch portion 41. And two outer convex portions 52 ′ which are respectively disposed on opposite ends of the outer connecting portion 包覆 and respectively wrapped on the inner convex portions 42 ′ each of the outer convex portions 界定 define a position on the sliding rod 92 The rolling wheel tracker can not only drive the pedal rods to move relative to the sliders 92, but also has the following effects: - the outer cushion layer 5 is made of rubber even if the sports equipment roller is continuously used. When the temperature rises for a period of time, the outer (four) 5 does not loosen the support tube 4, so durability is preferred. 2. Even if the convex portion f of the outer cushion layer 5 is soft, since the inner convex portion 42 of the branch pipe 4 has good supportability, the wheel rails 521 are not easily deformed, and the rolling path of the sports equipment roller is therefore Can be kept correct, thus increasing the limit. Third, the rubber with soft outer layer texture, 7 1 is thin, so the molding is easy, and can be used to reduce the vibration of the roller of the sports equipment, because the M310717 increases the user's operation of the sports equipment 9 Comfort.
