PROBLEM TO BE SOLVED: To provide a main rope length measurement device of an elevator which can make a worker in a machine room easily know that one end side of a thread body part of the main rope length measurement device is properly and surely positioned at a connection portion between a main rope and a car or the like.SOLUTION: In a main rope length measurement device for measuring a length of a main rope which hangs a car and a balance weight by a 1:1-roping method in a hoistway, there is provided a string-shaped or a narrow strip-shaped thread body part 32, and a guide part 40 which is arranged at a tip of the thread body part at one end side. The guide part 40 comprises: abutment detection means 44, 46 which detect that the guide part 40 abuts on a rope shackle which connects an end part of the main rope to a car or the like in a state that the main rope is inserted into a through hole 43; and notification means 45 which notifies a worker in a machine room at an apex of the hoistway that the detection means detects that the guide part 40 abuts on the rope shackle.SELECTED DRAWING: Figure 5
