This icon represents a walker. It is a letter A shape but instead of one line it has two with the top one being curved slightly. The bottom has one leg with a small square and one with a rounded wheel.
This Walker icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 6,000 icons, all in the same style and quality.
