To provide a coupler which can easily connect insulators.SOLUTION: An insulator coupler 30 for electric train track includes a stationery pin 10 having a head and a shank, and a cap 20 which is fitted to the stationery pin 10. The shank of the stationery pin 10 comprises a first shank part, a second shank part which has a diameter smaller than that of the first shank part, and a third shank part which has a diameter smaller than that of the first shank part and larger than that of the second shank part, in this order from the head side toward a tip side. In a radial direction of the shank of the stationery pin 10, a size of the head is larger than the diameter of the first shank part. The cap 20 has elasticity, and has a first open hole which has a diameter smaller than that of the third shank part and larger than that of the second shank part. A length of the first open hole is shorter than a length of the second shank part.SELECTED DRAWING: Figure 1
