2012年3月15日 久々の蕎麦ポタ/厚木「手作りの蕎麦 薫製 あり田」 大和市（神奈川県）に所用、距離こそ大した事無いが 丘陵地帯を何度も横切るのでアップダウンが多く 獲得標高はちょっとした峠越えをしたぐらいになるが 前回の浜名湖ランで運動不足を痛感したので自転車で行くこととする 前回に続きなぜか基地続き、米海軍.海上自衛隊共用の厚木基地 今日は米軍戦闘機の訓練は無い様で、自衛隊の哨戒機がタッチ＆ゴーを繰り返していました。 ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

久々の晴れ間で３本ローラー台練の効果
from 週末ちょっとだけでも自転車乗り

ここ数週間は週末のたびに雨。 春分の日も直前まで曇で降水確率４０％でしたが、晴れました。 前日は、大学時代の友人達と私としては深酒し午前様で帰宅したこともあり、いつもの江ノ島へ。 この雨つづきの週末は、三本ローラーでトレーニングしてたんですが、これが効果絶大。 車輪がぶれず、ピタっと安定した走りができます。 道路の白線の真上をトレースするのに何の苦労もありません。 三本ローラーは、ペダルをくるくると回すように漕がないと乗れません。 こけます。 家の中でこけると大変なことになるので、私は、両側に壁のある廊下で練習していました。 一漕ぎ目は、ズルズルと後輪が横滑りし、まったく乗ることができませんでしたが、そこはそれ、３５年のドロップハンドル歴（ブランクあり ...

Why the 1950s? (Part 1)

次回、この記事の日本語版を投稿します。 In this post I will begin addressing why I focus on Japanese bicycles from the 1950's. (Click on photo below) 1. Availability One obvious reason is availability. In 1932 Japan's bicycle industry started a long downward trend as it shifted from a free enterprise to a state controlled enterprise. Things became increasingly worse as Japan entered WWII with a decline in bicycle manufacturing as many plants were converted to munition plants to support the war effort. Lack of resources escalated the situation, many a bicycle was donated to scrap drives to be melted down and used for munitions. It is estimated that there were 10 million bicycles in Japan at the start of the war, by the end of the war that number was halved. After WWII there was a great demand for bicycles and many munition plants were converted to peacetime production, including bicycles. But materials were ratione ...

次回、この記事の日本語版を投稿します。 ( ↓ Click on the photo below ↓ ) In the previous post we took a look at how bicycle production began to be controlled starting in 1932; how bicycle plants were transformed into munition plants; how bicycles were donated to scrap drives in support of the war-effort; how in the period immediately after the war high demand and low supply, in addition to rationing, created a desperate situation whereby what was made in the morning sold in the afternoon on the black market; how bicycles where of questionable quality due to lack of standards and materials but still sold even without tires . To correct the inferior quality and establish a legal base for manufacturing standards, in June 1949 Japan enacted The Industrial Standardization Law which became the foundation for JIS (Japan Industrial Standards) . However, in the case of the bicycle industry, this was implemented incrementally and, as c ...

前回の投稿 では、
昭和20年代後半に入って自転車の需給が高まり、
輸入枠緩和により資材が入るようになって、
日本工業規格（JIS=Japan Industrial Standard) により品質が高まり始めたが、
自転車工業全体的に普及されるまで年月がかかったことを書きました。
ということは、品質標準化と部品互換性は昭和30年代後半以降。
このころは自転車は貴重な物で、庶民の手に入る唯一の交通手段で現代の自動車ほどの価値があり、一台は2ヶ月分の給料が掛かりました。
一家・一台・一生の時代。
軍需資材用工場が平和産業工場に変わったが、下記の写真が語るように自動化より手造りが圧倒的に多かったです。
当時の自転車が工芸品 ...

Why the 1950s （Part 3）

次回この記事の日本語版を投稿します。 （ ↓↓↓ Click on photo to enlarge ↓↓↓) In the previous post we saw that immediately after the war bicycles were in great demand and quality was questionable due to lack of materials as well as standards. However, in the early 1950's good materials are becoming available, with the passage of The Industrial Standardization Law which became the foundation for JIS (Japan Industrial Standards) standards began to slowly be implemented but would eventually take nearly a decade to spread throughout the entire bicycle industry. This means that quality and interchangability would not be complete until the early 1960's and that bicycles from the 1950's are largely crafted. At this time bicycles are the only affordable type of private transportation costing on average two months'salary and the status of a bicycle is nearly that of today's automobile. Although munition factori ...

Why the 1950s (Part 4)

次回、この記事の日本語版を投稿します。 （↓↓↓ Click on photo to enlarge ↓↓↓) In this post we continue to examine factors that contributed to making bicycles from the 1950's so unique. As noted earlier in the series (Part 1) following the war, munition plants were converted to peacetime production. So precision tooling for parts was in place, but, as noted in (Part 2) it took a decade (1953-63) for industrial standards to fully spread through the entire bicycle industry. This coupled with lack of automation (Part 3) meant that bicycles were still to some degree crafted and largely built by hand. Those former munition plants which converted to bicycle manufacturing included: Mitsubishi Heavy Industries (Tsu Machinery Works) Kayaba Industries (Gifu Works), Nihon Kinzoku Sangyo Nakanishi Kinzoku Handa Kinzoku Fuji-koshi Kozai, Fuji Sangyou (Ohta Works) Takasago Tekko, Amatsuji Kogyo Katakura Kogyo Nishinihon ...
