Commercial Vehicle
The Junior was a medium-size vehicle introduced to fill the gap between the Datsun and Nissan trucks. The first-generation B40 was launched in October 1956. Later, due to a change in the compact- vehicle standard, the newly designed model 40 was introduced in 1960. The 140, which integrated the Junior and Miler, was introduced in 1970 and in 1974, an improved model, the 141 (conforming to 1975 exhaust emission regulations), was launched.
