Abstract: An endoscope bending operation mechanism comprises an up-down bending operation knob (a left-right bending operation knob), an up-down bending pulley (a left-right bending pulley) supported for rotation by a pulley case, the up-down bending pulley is configured to move by an operation force from the up-down bending operation knob, an up-down bending operation wire (a left-right bending operation wire) having a proximal end and a distal end, the proximal end of which is connected to the up-down bending pulley (the left-right bending pulley) and the distal end of which is connected to a bending portion of an insertion section of an endoscope, a stopper member, a protruding portion, the stopper member and the protruding portion are movable relative to each other, an amount of relative rotation between the up-down bending pulley (the left-right bending pulley) and the pulley case is restricted by the protruding portion contacting the stopper member.

Abstract: Provided is an air-conditioning apparatus for vehicle including a main frame capable of being assembled without increasing the number of parts and the number of processes. An air-conditioning apparatus for vehicle includes a casing divided into an indoor chamber and an outdoor chamber by a partition plate, the casing including a cover placed on a top thereof, and a refrigeration cycle device placed across the indoor chamber and the outdoor chamber in the casing. Each of side plates, serving as side surfaces of the indoor chamber and the outdoor chamber, of the casing is extruded in one piece of aluminum.

Abstract: In the heat treating method, a raceway surface of an outer ring is subjected to heat treatment, while an entirety of an outer peripheral face of the outer ring is cooled by injecting water. Moreover, a raceway surface of an inner shaft is subjected to heat treatment, while a flange of the inner shaft is cooled by bringing it into contact with water. The cooling unit has a holding part for holding the flange while the flange is in contact with water.
