A gas compressor includes a main body portion having a compression unit configured to compress gas, a drive unit configured to drive the compression unit, and a storage part configured to store the gas compressed by the compression unit, a leg portion configured to support the main body portion and configured to be supported by a support portion provided on an auxiliary storage unit, and a fastening unit configured to detachably fasten the auxiliary storage unit and the main body portion. The leg portion includes a connecting buffer portion having elasticity and configured to be brought into contact with the support portion, and the fastening unit fastens the auxiliary storage unit by applying a force in a direction in which the first connecting buffer portion is elastically deformed.

The elevator includes an amplifier to amplify an acoustic signal; and an induction loop having looped wires that generate a magnetic field by current output from the amplifier, in which plural wire harnesses forming the induction loop are electrically connected to one another by plural connectors, which the respective wire harnesses have, coupled to one another; and the plural wire harnesses include a first wire harness having a first connector which is connected to the connection line to the amplifier, a second connector which is connected to the connection line to the winding start of the induction loop, and a third connector which is connected to the connection line to the winding end of the induction loop, and an elongated second wire harness which forms at least a part of the looped electric wires and has a fourth connector at one end and a fifth connector at another end.

Elevator

An air compressor includes a motor, a compression mechanism configured to be driven by the motor to generate compressed air, a tank configured to store the compressed air, a controller configured to control driving of the motor, an air extraction port configured to extract compressed air from the tank, and an extraction pressure sensor configured to measure an extraction pressure that is a pressure of compressed air extracted from the air extraction port. The controller is configured to control the driving of the motor by referring to the extraction pressure.
