Abstract:
PROBLEM TO BE SOLVED: To provide a rotating member position detection device and lens barrel that allow a detection sensor to accurately detect a position of a rotating member with respect to a first holding member.SOLUTION: A rotating member position detection device of the present invention comprises: a detection sensor 651 that detects a position of a stop blade operation member 61 rotatably held by a first holding member 62 and a second holding member 64 between the first holding member 62 and the second holding member 64 with respect to the first holding member 62; and a detection sensor holder 652 that holds the detection sensor 651 and is attached to the second holding member 64. The detection sensor holder 652 comprises two of first and second positioning shafts 652a and 652b that are arranged apart from each so as to be positioned with respect to the second holding member, and the first positioning shaft 652a is configured in such a way that a position of the detection sensor holder 652 with respect to the first holding member 62 is determined when positioned with respect to the second holding member 64.SELECTED DRAWING: Figure 2
