    摘要: A measuring instrument that includes a tube 21 having a female thread 211 and a spindle 3 having a lead screw 31 screwing with the female thread 211 and capable of being advanced and retracted in an axial direction along with rotation around the axial center, and measures dimensions etc. of a workpiece according to displacement in an axial direction of the spindle 3 based on a rotation amount of the spindle 3. According to this measuring instrument, a pitch P of the lead screw 31 is twice as large or more than the difference between an external diameter R and a core diameter r thereof, and the difference between the external diameter R and the core diameter r is one-fifth or less of the external diameter R. Because of the lead screw 31 with the large pitch, the spindle 3 can be moved at high speed, thus enhancing operational performance of the measuring instrument.

    摘要: In a starter with a planetary gear speed reduction mechanism, a first output shaft retaining member (retaining member 10, washer 20) and a second output shaft retaining member (pinion retaining ring 250) are mounted on an output shaft 220 in such a manner as to sandwich from axially front and rear directions a bearing support portion of a housing 400 which supports one end of the output shaft 220, so that a thrust load in the frontward and rearward directions of the output shaft 220 is received at the front and rear end faces of the bearing support portion of the housing 400. Therefore, the axially rearward movement of the output shaft 220 is regulated assuredly without regulating it by the rear end face of the center bracket 360 and the mortor partition wall 800, thereby preventing deformation of the center bracket.

    摘要: In a starter having a pinion gear on an output shaft driven by a starter motor, a magnet switch, and a shift lever pivotally connecting the pinion and the magnet switch, the shift lever is formed at one end thereof with an annular arm body for engagement with the pinion gear. The annular arm body is engaged with the pinion gear to receive the pinion returning force evenly thereby to prevent damage on the shift lever. Preferably the annular arm body is engaged with the pinion gear through a plate and a bearing.

    摘要: In a starter, one end of a spring is connected with a pinion, whereas the other end of the spring is connected with an annular plate. A regulation claw of a regulation member for moving the pinion toward a ring gear is made separate from the spring which is flexed in the rotational direction of an output shaft so as to engage the pinion with the ring gear, when the pinion is brought into contact with the ring gear. Thus, appropriate setting of the specification of the regulation claw of the regulation member and that of the spring can be very easily accomplished. Further, because the specification of the spring can be independently appropriately set without difficulty, the spring is made more durable.

    摘要: An electric rotating machine and manufacturing method of the same is provided that can securely press-fit magnetic poles against an inner circumference of a yoke with a cylindrical body. By directly contacting a first and second end portions of the cylindrical body and moving the same relatively, the diameter of the cylindrical body widens in the outer radial direction to press-fit the magnetic poles against the inner circumference of the yoke. Thus, the variation of the inner diameter of the magnetic poles that occurs due to the dimensional error in permanent magnet thickness and inner diameter of the yoke is absorbed by the relative movement of the first and second end portions. This stabilizes the fixing force of the magnet, and allows the magnet to be securely fixed to the yoke without excessive stress on the cylindrical body. Furthermore, the displacement of the magnetic poles can be restricted by bending axial ends of the cylindrical body radially outwardly.

    摘要: An electric rotating machine which withstands mechanical and thermal loads applied thereto is provided. Coil arms and coil trunks are provided in roughly parallel orientation to the end faces of an armature core only through insulating rings and insulating spacers. Metal brush is disposed on coil arms constituting a commutator, whereby the overall length of the armature can be remarkably shortened. The coil arms are strongly pressed against and fixed to the side of armature core by a collar, so that the resistance to the centrifugal force can be remarkably improved. A cylindrical ring is circumferentially fitted on the upper coil trunks to prevent radially outward movement of the coil arms due to the centrifugal force. The coil arms disposed in a non-commutator side are made radially shorter than those disposed in the commutator side. Thus, electric resistance of an armature coil is reduced and radial movement caused by the centrifugal force is reduced.
