    • Disclosed is an optical switch for changing over the mode connecting two optical transmission lines comprising two optical fibers directly to each other and the mode connecting an optical communication device between the two transmission lines. In this optical switch, in order to reduce the insertion loss, first, second, third and fourth optical fibers, each having an optical connector attached to one end, are attached to a substrate so that at least parts of the respective optical fibers are fixed to the substrate, and the ends of the first and second fibers are arranged on the substrate movably so that the end face of the first optical fiber confronts the end faces of the second and third optical fibers and the end face of the second optical fiber confronts the end faces of the first and fourth optical fibers.

    • [Object] An object is to obtain an indoor unit of an air-conditioning apparatus, the indoor unit including a propeller fan in the vicinity of an air inlet, the indoor unit being capable of ensuring the strength of a casing and suppressing degradation of performance by reducing an increase in draft resistance of sucked-in air.[Solution] In an indoor unit 1 of an air-conditioning apparatus, at least one propeller fan 10 having a fan guard 50 is disposed downstream of an air inlet 130 formed at the top of the indoor unit 1. The air inlet 130 is provided with bars 140. Each of the bars 140 is located, in a vertical cross-section perpendicular to the longitudinal direction of the bar 140, within a virtual cylinder 13 obtained by projecting a boss 11 of the propeller fan 10 in the direction of the rotation axis of the propeller fan 10.
