In addition, in the drawing, the shaft hole n of the outer wheel 1 is a coaxial ring sleeve, and the shaft hole ring wall 21 of the inner wheel 2 is coaxially pivoted on the inner wheel 2, and the three clothesets 12 of the outer wheel 1 are evenly distributed at an equal angle. And respectively axially opening to the outer side of the shaft hole 1 ^ and connecting the shaft hole 11 respectively, and the three pocket portions 12 respectively include a bottom surface 18 of the bag, each of the bottom surfaces 18 of the bag being radially inclined and thus A relatively wide portion 13 and a relatively narrow portion 14 are formed, and three roller cutters are respectively disposed in the two pocket portions 2 and are respectively adjacent to the shaft hole ring wall 21 of the inner wheel 2. Further, each of the pockets 12 of the outer wheel 1 has a relatively wide portion 13 of the bottom surface of the pockets 8 and is recessed radially outwardly with a receiving recess 16 and correspondingly accommodates each of the rollers 15. In the present embodiment, the bottom surface of each of the pockets 12 of the outer rim is formed in a curved shape and has different curvatures. Although, at least one of the bottom surface 18 of the bag and the receiving groove 16 may be linear in the shape of 200801364, or both of them may be sized to accommodate the roller and may be linearly shaped and accommodated in the design. As a matter of course, the elastic file of each of the pockets 12 of the outer wheel 1 includes a spring 171 and a top abutting member (7), and wherein: two: 17 two-elastic pre-forces 172 corresponds to the top roller 15 respectively. The operation of the above structure will be described later. When the electric start function is performed by pressing the = switch (not shown), the power (5) (not shown) will start to rotate. In this embodiment, it is reverse time, and the power source 3 The rotational power is transmitted to the inner wheel 2, at which time the outer wheel 1 has not started to rotate. When the inner wheel 2 rotates and the rotational speed increases, the friction between the shaft hole ring wall 21 of the inner wheel 2 and the roller 15 of the outer wheel 1 and the action of the outer portion of the bag portion 12 against the roller 15 are And the roller 15 of the outer rim will move along the bottom surface of the bag in the pocket portion 12 and the roller 15 will roll to the relatively narrow portion. At this time, the rafter 15 will abut against the shaft hole wall 2 i, Therefore, the rotational power of the inner wheel 2 is rotated counterclockwise via the action of the roller 15 against the shaft hole ring wall 21. After that, the outer wheel 1 will start to rotate, and when the rotation speed thereof is increased, the elastic preload of the elastic member 17 of the outer bag 20 1 bag portion 12 is insufficient to support the roller 15 again. At this time, the roller 15 will be in the bag portion 12. The inner roller 2 is further rolled along the bottom surface 18 of the bag to the relatively wide portion 13, and the power of the inner wheel 2 and the outer wheel is cut, that is, the inner wheel 2 does not rotate, and the outer rim continues to rotate. At this time, the outer rim can be rotated. The engine (not shown) connected to the locomotive (not shown), that is, the inner wheel 2 and the outer wheel 200801364 can be made to have the function of a one-way clutch, so that the locomotive (not shown) starts the locomotive with the power source 3 The engine (not shown) (not shown) achieves the electric start function of the locomotive (not shown). Please note that when the roller 15 of the outer rim is rolled along the bottom surface 18 of the bag to the relatively wide portion 13 of the bag, the roller 15 is accommodated in the receiving groove 16, that is, the above structure can make the roller of the outer rim The 丨5 is rolled to the relatively wide portion U of the pocket portion 2, and can be received and thus positioned in the accommodating recess 16 recessed radially outwardly of the relatively wide portion 13, thereby positioning the roller 15 of the outer rim In a stop position, 1 when the speed of the locomotive (not shown) is at the critical speed or the speed is unstable, the roller 15 of the outer wheel 1 will still be positioned at a stop position without rolling forward and backward ( In the case of beating, and thus the roller (10) of the outer wheel i can be prevented from hitting the sound, abrasion, and the like, and the power is not lost. The above-described embodiments are merely examples for convenience of description, and the scope of the claims is intended to be based on the scope of the claims, rather than the above embodiments.
