Wiring-harness connection structure of transmission shift-lever device

A wiring-harness connection structure of a transmission shift-lever device including a shift knob with a switch, said shift knob being fitted onto an upper end of a shift lever and projected from an elongated shift slot of a position-indicator cover, said connection structure comprising:

• a conducting line (6) connected to a switch (3) attached to a shift knob (1) at an upper end thereof, said conducting line (6) partially exposed inside of a lower opening end (11) of the shift knob at a lower end thereof to provide a male plug (8);
• a wiring-harness connector (19) having a female receptacle (16) fittable onto said male plug (8), a first caulked portion (21) caulked onto an endmost stripped, non-insulated wire portion of a harness end (15a) of a wiring harness (15), and a second caulked portion (21a) caulked onto a wrapped, insulated wire portion of said harness end (15a);
• a conducting-line guide (9c) integrally formed with the shift knob near said lower opening end (11), said conducting-line guide having a guide hole (9d) into which said male plug of said conducting line (6) is inserted and a cylindrical hollow portion (7) into which said male plug (8) is partially exposed via said guide hole (9d), said conducting-line guide (9c) being provided for fully accommodating said harness connector (19) in said cylindrical hollow portion (7) for electrical insulation;
• and
• a harness holder (14) having a harness-end mounting hole (18) into which said harness end (15a) is fittable, said harness holder (14) being detachably fitted to the lower opening end (11) of the shift knob (1) for preventing said harness connector (19) and said harness end (15a) in connection from disconnecting from said harness holder (14) by abutment between said second caulked portion (21a) and said harness holder (14).
