In the prior art, the input disk and the input shaft are formed separately, and the two are interlockedly connected by the engagement of the engaging portion. It is hoped that the vibration is transmitted to the input disk side by the engaging portion, and compared with a configuration in which the input disk and the input shaft are integrally formed (for example, see Japanese Patent Application Laid-Open No. 1-295071). However, the degree to which the press-fitting accuracy and durability between the input disk and the umbrella-shaped cone are deteriorated by the rotational runout of the input disk will be temporarily reduced, but in this conventional technology,
The engagement portion that interlocks the input disk and the input shaft is not provided with a specific structure for positively preventing the transmission of the rotational runout, and the input pulley is directly mounted on the input shaft. The tension of the belt wound around the input shaft is applied to the input shaft as a bending load, and the rotational vibration of the input shaft becomes large. there were. In the above-mentioned Japanese Patent Application Laid-Open No. 1-295071, the input pulley is supported on the case separately from the input shaft, but the input pulley is rigidly connected integrally to the input shaft. Therefore, in the end, the pulling force of the belt wound around the input pulley reaches the input shaft.

According to the present invention, an input shaft (17) formed on an inner end face of an input shaft (17) is engaged with a driven engagement portion (4a) formed on an input disk (4) side so as to face an input.

The radial thickness of the driven disc (4) on the input disk (4) side
The input pulley (19) transmitted to the input shaft (17) is formed smaller than that of the input shaft (17) so that a gap is formed between the two engagement portions (17a) and (4a). ) And a bearing (2) on the outer circumference of the cylindrical portion (18) extending from the case (1).
0), the driving side engaging portion (19a) formed on the input pulley (19) is formed so that a gap is formed between the driving side engaging portion (19a) and the inner periphery of the cylindrical portion (18). A torque is transmitted from the input pulley (19) to the input shaft (17) by engaging with a driven side engaging portion (21a) provided on a joint (21) fixedly mounted on the input shaft (17). Due to the input shaft structure, the input pulley (19) to which the belt tension is applied is securely supported by the case (1), and less bending load is applied to the input shaft (17). Even if vibration occurs, the vibration is transmitted to the input shaft (17), and the drive-side engaging portion (19a) on the input pulley (19) side is brought into contact with the inner periphery of the cylindrical portion of the case (1). Torque transmission engaged with the driven-side engaging portion (21a) formed on the joint (21) attached to the input shaft (17) such that a gap is created between As a result, the rotational vibration of the input shaft (17) is reduced, and the rotational vibration of the input shaft (17) is transmitted to the input disk (4). The radial thickness of the portion (17a) is smaller than that of the driven engaging portion (4a) on the input disk (4) side so that a radial gap is formed between the engaging portions (17a) and (4a). The rotational force transmission configuration made possible further reduces the effects, and these are synergistic, and the rotational vibration of the input disk adversely affects the pressure contact accuracy and durability between the input disk and the umbrella cone. As a result, the desired shifting function was fulfilled with high durability.
