Abstract(J)	大型車の車輪脱落事故が後を絶たない．適正な締付けトルク管理と増締めの必要性が関係団体から指導されている．ここでは，トルク法の特性からホイールボルトのゆるみ原因を検討し，ゆるみ防止法を提案する．トルクレンチで締付ける場合，高い初期軸力や，増締めを行っても十分な締付け力が得られない可能性がある．このことから，ホイールボルトのゆるみ防止には，効果的なゆるみ止め部品・装置やゆるみ止め方法を併用する必要がある． Translation
Abstract(E)	Accidents involving wheel falling off in heavy-duty vehicles continue. This study examines the causes of wheel bolt loosening based on the characteristics of the torque method (calibrated wrench method), and examines and proposes measures to prevent loosening.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
