A sliding component 10 slidably supporting an object includes a non-conductive first sliding part 1 with a sliding surface making contact with the object and a conductive member 2 provided in the first sliding part 1 or on a side opposite to the sliding surface of the first sliding part. Wear of the first sliding part 1 is detected by detecting a conduction state in the conductive member 2.


An instrument control device includes a variable mechanism including a motor configured to adjust a state of an instrument, and a variable controller configured to variably control the motor with a command signal. The variable controller includes a receiver configured to receive a communication signal output from a remote controller and output a received signal in accordance with the communication signal, and a motor controller configured to increase the command signal stepwise starting from input of the received signal until a rotational speed of the motor reaches a predetermined rotational speed.


A holder is used while attached to a chassis of a vibration generator that moves a vibrator to generate a vibration. The holder includes a vibrator retention unit retaining the vibrator, a fixed unit fixed to the chassis, and an arm. The arm connects the fixed unit and the vibrator retention unit, and the arm supports the vibrator retention unit while the vibrator retention unit can be displaced with respect to the fixed unit. The fixed unit, the arm, and the vibrator retention unit are integrally formed using resin.

A vibrator-mounted holder is attached to a casing of a vibration generator which moves a vibrator to generate a vibration when used. The vibrator-mounted holder includes a vibrator, a vibrator retention unit retaining the vibrator, a fixing unit fixed to a casing, and an arm. The vibrator includes a magnet having a plate shape parallel to a horizontal surface and a yoke arranged on the magnet. The arm connects the fixing unit to the vibrator retention unit, and supports the vibrator retention unit in a manner that the vibrator retention unit is displaceable with respect to the fixing unit. The yoke has a projecting portion which is projected downward and fixed to the vibrator retention unit. The arm is connected to a portion, at which the projecting portion is arranged, within the vibrator retention units.
