摘要： An inserting portion of a holding case holding a sensor is inserted in a fitting hole formed in the cylindrical wall portion of the cover. The hold-down frame portion of a hold-down member pivoted to the cylindrical wall portion is used to press the base portion of the holding case against the outer peripheral face of the cylindrical wall portion. The contact area between the base portion and the cylindrical wall portion is shut with an O-ring, so that any extraneous matter such as rainwater is prevented from penetrating into the cover. Also, a pair of elastic retaining pieces are provided for a plastic material which embeds a sensor. A pair of retaining projections are provided on the outer peripheral edge of a collar portion formed in the leading end portion of a cylindrical holding portion provided for a cover. While a corrugated sheet spring is elastically compressed in between the stepped portion of the plastic material and the collar portion, the retaining projections are each made to engage with retaining holes formed in the elastic retaining pieces. An O-ring retained by the outer peripheral face of the intermediate portion of the small-diameter portion of the plastic material is used to seal up the contact area between the outer peripheral face of the small-diameter portion and the inner peripheral face of the cylindrical holding portion.

摘要： The sensor 20a has first and second permanent magnets 31, 32, stator 33 and coil 24. The first and second permanent magnets 31, 32 has an inner peripheral face formed with south and north poles circumferentially and alternately with a uniform space therebetween. Holes 17a, 17b are formed circumferentially with a uniform space therebetween in the tone wheel 13. At the moment when all the south poles in the first permanent magnet 31 are opposed to the holes 17a, all the north poles of the second permanent magnets 32 are opposed to the holes 17b, resulting in that the alternating magnetic flux flows in the stator 33 and the electric voltage is generated alternately in opposite directions in the coil 24 as the tone wheel 13 rotates.

摘要： It is an object of the invention to provide a wheel-driving unit which is small in size and weight, can facilitate its assembling operation, and can prevent generation of jarring teeth striking sounds, and a method for manufacturing the same. The circumferential-direction widths of teeth respectively constituting a male spline portion (47a) formed in the outer peripheral surface of a spline shaft (17) and a female spline portion (48a) formed in the inner peripheral surface of a spline hole (14) are varied gradually in the respective axial directions of the male and female spline portions (47a), (48a). The directions where the widths of the teeth respectively constituting the male and female spline portions (47a), (48a) increase in the axial direction are set so as to differ from each other, whereby the spline teeth respectively constituting the male and female spline portions (47a), (48a) are engaged with each other in a wedge-like manner. A retaining ring (33b) is bridgingly interposed between the outer peripheral surface of the outer end portion of the spline shaft (17) and the inner peripheral surface of the near-to-outer-end portion of the spline hole (14) to thereby prevent the spline shaft (17) from slipping out of the spline hole (14).

摘要： A radial ball bearing 14 of the three point contact type or four point contact type is used for the rolling bearing for a compressor pulley. The offset amount &dgr;, that is the axial distance between the center &agr; of the radial load applied to the follower pulley 4 from the endless belt 11, and the center &bgr; of the radial ball bearing 14 is 40% or less of the diameter of the pitch circle. In addition, the radial clearance of the radial ball bearing 14 is 0.2% or less of the diameter of the pitch circle. With this construction, the durability of the rolling bearing to support the follower pulley 4 is secured while made compact.

摘要： One-way clutch 18 has a spring the elastic modulus of which is limited up to a predetermined value, seal rings 36a, 36b have a sliding resistance with respect to the inner rings 22 which is limited up to a predetermined value, and support bearings 17a, 17b have a rotation resistance which is limited up to a predetermined value. The torque required to rotate the driven pulley 7a relative to the sleeve 8a in the direction for overrun condition is limited up to 0.5 N•m. Accordingly, the power generating efficiency of the alternator is secured while abnormal sounds are prevented from occurring with the life of endless belt being prevented from reducing.
