Abstract: A variable magnification optical system has, in order from an object side: a first lens group having positive refractive power; a second lens group having negative refractive power; an aperture stop; a third lens group having positive refractive power; and a rear lens group. Upon zooming from a wide-angle end state to a telephoto end state, at least the rear lens group is moved toward the object side, and distances between the lens groups are varied. Upon focusing from an infinitely distant object to a closely distant object, the third lens group is moved along the optical axis. At least a portion of the rear lens group constitutes a vibration reduction lens group having negative refractive power and moveable perpendicular to the optical axis.

Abstract: The present invention provides a flow channel switching valve with a reduced number of components as well as a reduced weight, and a method for assembling the same. A valve shaft adapted to be coupled to a valve element so as to transmit torque of a rotary drive portion to the valve element is inserted through a vertical through-hole, which penetrates through the valve element in the direction of the rotation axis O (i.e., vertical direction), and through a fit-insertion hole provided in a valve body. Then, a drive gear that forms the rotary drive portion is fixed to the upper coupling portion of the valve shaft protruding from the fit-insertion hole so that the valve shaft is rotatably supported with respect to the valve body.
