はその設定位置について特段の配慮が必要になる。In order to solve this problem, it is conceivable to provide the attachment member of the suction pad with a fragile portion that is deformed or broken by an external force of a predetermined size or more. However, since the pipe connected to the vacuum source is mounted on the mounting member, the strength of the fragile portion changes depending on the strength of the pipe. Special consideration must be given to the location.
［考案が解決しようとする課題］ 本考案が解決しようとする課題は、強度設定が容易な
脆弱部を有する真空パッドを提供することにある。[Problem to be Solved by the Invention] A problem to be solved by the invention is to provide a vacuum pad having a fragile portion whose strength can be easily set.
