  • Patent number: 8272282
    Abstract: In a starter motor equipped with a shock absorbing device, a disk spring is placed between a bottom part of a cylindrical casing and one side of a disk stack structure composed of rotatable disks and fixed disks which are alternately stacked. Caulking parts formed at an opening end of the cylindrical casing are bent toward the inner diameter side of the cylindrical casing in order to push the disk spring toward the bottom part side of the cylindrical casing through the disk stack structure. The disk spring accumulates reaction force (or elastic force) by the caulking. The reaction force accumulated in the disk spring pushes the disk stack structure to the axial direction of the cylindrical casing. The structure of the shock absorbing device can supply a uniform load to the disk spring, and provides a stable shock absorbing capability.

  • Publication number: 20120087720
    Abstract: In a dissimilar material joint structure that joins together an anti vibration bar (first member) 14 and a end cap (second member) 15, which is a dissimilar metal material to the anti vibration bar 14, the anti vibration bar 14 is sandwiched by a plurality of end caps (second members) 151 and 152, and these respective end caps 151 and 152 are joined together by welding. Due to contraction of a weld material 153 welding the end caps 151 and 152, the anti vibration bar 14 is sandwiched between the end caps 151 and 152, whereby the anti vibration bar 14 and the end cap 15 are joined. Consequently, a thermal treatment for welding dissimilar metal materials is not required, and the welding operation can be carried out easily.
