  • Patent number: 10720744
    Abstract: A heat-shrinkable tube fitting jig is used to fit a heat-shrinkable tube onto a terminal-attached electric wire formed by crimping a core wire crimp portion of a terminal onto a core wire of an electric wire. The heat-shrinkable tube fitting jig is provided with a first side abutting plate, a second side abutting plate member, and an electric wire holding portion. Columnar bodies and recessed surfaces, which constitute terminal positioning portions, are provided on the upper surface of the first side abutting plate. A first side end face and a second side end face of the heat-shrinkable tube are abutted against mutually opposing surfaces (a first side abutting surface 40S and a second side abutting surface 44S) of the first side abutting plate and the second side abutting plate.
