Abstract

A steering wheel includes a boss, a spoke, and an air bag apparatus with a bag and a synthetic resin cover. When the vehicle is subjected to a collision, the bag is inflated and rupture opens a front wall of the cover. The front wall has two side rupture lines, a dividing rupture line between the side rupture lines, a center rupture line from the dividing rupture line, and two upper hinges between the side rupture lines and the center rupture line. When the cover ruptures open, the rupture lines rupture, causing each lid to bend and swing about the upper hinges. The dividing rupture line is disposed at a position so that the upper lids do not interfere with the rim.
