Abstract(J)	ねじは長い歴史を持った機械要素であるにもかかわらず，今日でも締付け不良，ゆるみ，強度不足などのトラブルが後を絶たない．それは，ねじがその形状から本質的に強度上の問題・ゆるみの問題などを持っていたからであろう．本稿では，ねじのゆるみや破損の原因およびその防止法などについて現状の課題と動向を述べる． Translation
Abstract(E)	Although screws and/or bolted joints are mechanical elements with a long history, troubles such as improper tightening, looseness, and insufficient strength continue to occur today. This is probably because the screws had essential strength and looseness problems due to their shape. In this commentary, we describe the current issues and trends regarding the causes of loosening and breakage of screws and how to prevent them.

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".
