Abstract: A robot cleaner including a cleaner main body configured to travel and clean a cleaning area, a sensor case arrangeable on the cleaner main body such that while the sensor case is arranged on the cleaner main body, the sensor case is configured to cover a sensor for detecting an obstacle in the cleaning area, and a sensor collision detector configured to detect an impact applied to the sensor. The sensor collision detector includes a bumper connectable to the sensor case which covers the sensor such that while the bumper is connected to the sensor case, the bumper is moveable and at least a portion of the bumper is arranged along an outer circumference of the sensor, a detecting portion to interact with the bumper to detect a collision of the sensor case, and wherein the bumper and the detecting portion are on a lower side of the sensor.

Abstract: A noise reduction apparatus for a shift cable, may include a mounting socket that is fixed to a shift lever mounting bracket, with an inner cable of the shift cable therethrough, a cable connection pipe that has one side connected to a shift lever-sided end of an outer cable of the shift cable, and a housing connection pipe that has one end elastically-coupled to a shift lever-sided end of the cable connection pipe with a predetermined distance therebetween by a first antivibration member in a damper housing and the other end thereof elastically-connected to the shift lever mounting bracket by a second antivibration member in the mounting socket.
