  • Publication number: 20150330457
    Abstract: The purpose of the present invention is to provide a yoke and shaft joint structure with which joint strength of a metal junction of a yoke and shaft that configure a steering device can be obtained with a very simple structure and a very small size, and a joining method therefor. The joint structure is obtained from a yoke (A) having a cylindrical section, a shaft (3) having a joint-side shaft end (31) that is joined by metal to the cylindrical section (2), and a synthetic resin covering (4) that covers the entire circumference of the junctions site of the cylindrical section (2) of the yoke (A) and the joint-side shaft end (31) of the shaft (3). A portion of the synthetic resin covering (4) is filled and solidified in yoke through holes (23) formed in the cylindrical section (2) and shaft through holes (33) formed in the joint-side shaft end (31) of the shaft (3).

  • Patent number: 7021976
    Abstract: A spring connector comprises a supporting member, a cylindrical plunger, and a coil spring provided in the cylindrical plunger. The supporting member has a base, a pillar extended from the base, and a shoulder and a head having a diameter larger than that of the pillar. The upper end of the head has an inclined surface. The plunger has a closed upper end, an opening formed in an annular bent portion of a lower end thereof. An annular edge of the opening is slidably engaged with the supporting member at the shoulder thereof. The coil spring is provided between the closed upper end and the inclined surface of the head so that a shoulder formed on the head at a lower annular periphery is pressed against the annular bent portion of the opening.

  • Patent number: 6719501
    Abstract: A cemented carbide end mill has three or more cutting edges formed on its periphery and flutes each provided between adjacent cutting edges. The land width of each cutting edge and the flute width has a ratio of 1:1.5 to 1:4. Each flute has a helix angle of 35°-60° and, when viewed in a cross section perpendicular to the end mill axis, is in a shape smoothly concave radially inwardly. The core of the end mill has a diameter which is 62%-68% of the outer diameter of the end mill. The cutting edges have a base material of ultra-fine cemented carbide and are coated with a titanium-aluminum nitride hard film. The end mill is good at chip discharging in groove cutting and provides less inclination of cut grooves and less corner wear of the end mill.
