One person can grip one handle in a bus or subway existing today. Handles particularly lack in the commute time when many people use it. This can cause dangerous conditions when quick start or sudden stop happens. I suggest this design to improve this. This is a picture showing a bus packed with people. To lessen dangerous condition because of few handles to grip, I designed it multi-seizable. Compared to the existing handle, the knob is horizontally stuck out so that many people can hold on to it at the same time. It is more effective with space as one handle could be held by four people or more.
