  • Patent number: 8955361
    Abstract: In a steering device having a steering lock device, stress applied to a base portion of a flange section is reduced. Relief portions have round corners formed where the relief portions meet the outer periphery of the outer column, respectively. With the relief portions concave by ?3 from the mounting surface, radius R1 of each of the round corners of the relief portions can be made larger than radius R2 of a round corner of the mounting surface. This makes it possible to avoid interference between the relief portions and the corner at an inner end, in the vehicle width direction, of the right clamping surface of the steering lock device.

A helical fin is pressure formed on the outer surface of the outer tube and simultaneously a small helical groove is formed on the inside surface of the outer tube which follows the path of the helical path of the helical fin. The internal pressure being applied to the inner tube causes the inner tube to expand and conform to the inside surface and diameter of the outer tube, with a continuous helical protrusion forming which mates with the internal helical groove of the outer tube, but not entirely filling the internal groove. A helical passageway between the inner and outer tubes is thereby formed. Preferably the inner and outer tubes are made of copper.

A plurality of arms are pivotably secured to the bar, each having fingers directed and biased towards the longitudinal axis of each shaft. Each shaft is rotatable and carries an opening at a discrete location in the surface thereof. Rotating the shaft to a position corresponding to deenergizing the associated heating element of the range into an off position permits the free end of the finger to enter the opening, preventing further rotation of the shaft when the bar is slidably positioned into a locked position by the operation of a key operated lock.
