However, * When the rotation speed of the engine E gradually increases, the centrifugal weight 12 of the driving pulley 4 of the belt-type stepless speed changer B moves to the radial direction outside due to the centrifugal force, and the movable side pulley half 6 faces closer to the fixed side pulley half Move in the direction of body 5. The proximity of the two pulley halves 5, 6 narrows the width of the V space formed between the two, so that the belt 13 is moved to the outer side in the radial direction of the drive pulley 4. When the belt 13 moves to the outside, the movable pulley half 23 on the side of the driving pulley 21 presses the belt 13 to move to the left at the same time against the elastic force of the spring 24, and is formed in the two pulley halves 22, 23 As a result, the width of the V-space is widened, and the belt 13 moves parallel to the inner side of the driven pulley 21 in the radial direction. The stepless speed change by using one of the methods allows the engine E to be located in a low ratio area where the speed is relatively large at low speeds and in a high ratio area where the speed is relatively small at high speeds. In addition, when the two-wheeled vehicle is running, because most of the high-frequency areas travel, the belt-type stepless speed changer BM operates more frequently in the high-rate areas than in the low-rate areas. 0 This paper is in accordance with China National Standard (CNS) A4. Specifications (210 X 297 mm) 12 ------- 1 ------------ Order --------- line · (Please read the precautions on the back first Fill in this page) A7 B7 i. Description of the invention (10) (Please read the precautions on the back before filling this page) In addition, during the normal operation of this power section P, there is no endless belt 13 & A specified gap is formed between the driving pulley 4 and the driven pulley 21 between the inner peripheral surface of the belt 13 and the belt guide surface 43 of the guide roller 33. In this way, unnecessary contact between the belt 13 and the guide roller 33t can be avoided, and the durability of the belt 13 caused by frictional heat caused by such contact can be prevented from being reduced. In addition, due to the vibration of the driving pulley 4 or the read wheel 21, the changes in the side pressure between the belt 13 and the belt 13, the change in the frictional force of the belt 13, the change in the torque of the engine E, etc., may cause an abnormality in the belt 13. Vibration, in one case, contacting the inner peripheral surface of the & belt 13 with the outer peripheral surface of the guide roller 33 (ie, the belt guide surface 43) can effectively suppress the vibration, and can reduce the The touch sound generated by contact with the housing body 1 is, in particular, in the first embodiment + 'the inner peripheral surface of the belt 13 and the belt guide of the guide roller 33 are changed according to the operating state of the belt-type stepless speed changer B The contact state of the leading surface 43 can further reduce the occurrence of the touch sound. In addition, the durability of the belt 13 can be greatly improved. The operation state will be described in detail below. Printed by a member of the Intellectual Property Bureau of the Ministry of Economic Affairs and a consumer cooperative ① When the belt-type stepless speed changer operates in a relatively low ratio area with a relatively large transmission speed, as shown in FIG. 4, the belt 13 moves in parallel to the side of the housing body 1 The position of the solid line on the right side of 2, 4 is located at a position deviating from the center of gravity position C of the cross section of the belt 13. In addition, the inner peripheral surface of the belt 13 faces the first guide portion 43i formed by the large-diameter bulging portion of the guide roller 33. In this way, the gap 6 between the inner peripheral surface of the belt 13 and the belt guide surface 43 of the guide roller 33 is narrowed. When the belt 13 vibrates abnormally, the belt 13 is embedded in the narrow gap di described above. The stepwise inclined contact of the inner peripheral surface of the belt 13 applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -1 3-A7 ___B7_ 5. Description of the invention (Η) (Please read the precautions on the back before filling out this page) The first guide 43t formed by the diameter bulge, or the first, second The guide portions 43j and 43 2 can be used to make the contact area smaller and make uneven contact. In addition, the first guide portion 431 can be softened from low strength to make the belt 13 cushioned. The contact, using the multiplication effect on M, can effectively reduce the belt contact noise caused by the belt 13 contacting the guide roller 33. According to the above-mentioned method, when the belt-type stepless speed changer BM operates in the low ratio area, it can further reduce the above-mentioned belt touch sound caused by the vibration of the ear-level belt 13 which is easily felt by the user. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs ② When the belt-type stepless speed changer BM is operated in a high-ratio area with a relatively small speed, the belt 13 moves in parallel to the side of the body 1 of the newly opened housing (that is, the figure (Left side of 2, 4) As shown by the two-point chain line, the inner peripheral surface of the belt 13 faces the second guide portion 432 formed by the flat surface of the guide roller 33. In this way, the gap between the inner peripheral surface of the belt 13 and the belt guide surface 43 of the guide roller 33 is wider than that in the low ratio area described above. When the belt 13 vibrates abnormally, its inner peripheral surface and guide The frequency of contact of the belt guide surface 43 of the guide roller 33 can be greatly reduced when compared with the case of the above-mentioned low ratio area, and when it comes in contact, the inner peripheral surface of the belt 13 and the guide roller 33 The flat second belt portion 432 is in contact with each other, so that the contact area can be increased when compared with the case of the low ratio region described above. In addition, the belt 13 of the belt-type stepless speed changer B is more stable in the high-rate area than in the low-rate area, because abnormal vibration becomes less, so in the high-rate area, as described above, it is the same as the guide roller 3 3 The contact ratio becomes smaller, and the contact area between the belt 13 and the guide roller 33 becomes larger. It can be used to reduce the size of leather paper. Applicable to China National Standard (CNS) A4 (210 X 297 mm) -14-

In addition, item 4 of the patent application range according to the present invention is the item 1, 2, or 3 of the above-mentioned patent application scope, in which the above-mentioned guide member is composed of a guide roller and is provided on the above-mentioned drive pulley and the The middle of the driving pulley is formed in a freely rotatable manner, and the outer peripheral surface has a belt guide surface facing the inner peripheral surface of the belt, and the belt guide surface is provided with the above-mentioned first section formed by a large-diameter bulging portion. In addition to the above-mentioned effect, the guide portion and the second guide portion formed by a flat surface having a diameter smaller than the guide portion can rotate the guide roller when the belt contacts the guide roller. 'As a result, the friction of the belt and the guide roller is further reduced. In addition, according to item 5 of the scope of patent application according to the present invention, the above-mentioned guide member is formed integrally with the surrounding body of the belt by being formed into a protruding body shape surrounding the above-mentioned belt-type stepless speed changer. The facing skin and stomach guide surface forms the above-mentioned first guide portion composed of a high-level surface and the second guide portion composed of a low-level®, and the clearance between the above-mentioned first guide portion and the peripheral surface of the belt is smaller than that described above. In addition to the effects described above, the gap between the second guide portion and the peripheral surface of the belt is not limited to the above. The guide member of the guide belt is guided by the upper and lower fixed guide pieces integrated with the housing body. Formed, so the number of components and the man-hours of the combination can be reduced by K to achieve a significant cost reduction.
