PROBLEM TO BE SOLVED: To obtain a monitoring camera capable of extending the service life of a slip ring without attaching a vibration-proof material to a slip ring shaft. SOLUTION: At a stationary state that a camera part 7 is not rotated, the size of a fitting hole of a shaft 5 is made larger than the size of the slip ring shaft 4a so that a non-contact state of the fitting hole of the shaft 5 and the slip ring shaft 4a is maintained. Thus, the service life of the slip ring 4 is extended without attaching the vibration-proof material to the slip ring shaft 4a of the slip ring 4. COPYRIGHT: (C)2007,JPO&INPIT
