[Reproduction of Private Spring Preparatory School Lecture 7] The Emergence of Automobile Springs, the Great Earthquake, and the Major Advancement of Automobiles! The late Taisho period was an era when spring research became full-fledged.
In the previous discussion, we talked about the beginning of domestic production of spring materials in the early Taisho period, and how various manufacturing facilities and testing equipment were established, leading to a significant leap forward. This time, let's continue with the late Taisho period.
By the early Taisho period, the main railway lines were mostly constructed, and streetcars were operating in large cities; however, it was still the era of horse-drawn carriages and rickshaws. During this time, bicycles and automobiles were rapidly gaining popularity.
However, while bicycles were becoming common, automobiles were still vehicles for the privileged class, and it was not yet the case that everyone could have one, as is the case today.
Nevertheless, as vehicles changed, it was inevitable that springs would also change, and spring manufacturers had no choice but to start producing automobile springs.
