1. An air bag comprising:
- an inflation section having opposing wall portions that become spaced apart from each other during inflation by an inflating gas; and
linear joined portions disposed in the inflation section that linearly join the opposing wall portions, each of the linear joined portions comprising a body portion and at least one end portion, wherein;
an outer periphery of the at least one end portion is connected to an outer periphery of the body portion;
the at least one end portion is wider than the body portion;
the outer periphery of the at least one end portion is defined by at least three straight portions and connecting portions, wherein the connecting portions are located between adjacent ones of the at least three straight portions;
each of the straight portions is parallel with yarns that weave the air bag; and
the at least three straight portions comprise;
a first straight portion and a second straight portion that are parallel to each other; and
a third straight portion extending perpendicularly to the first straight portion and the second straight portion, the third straight portion having curved end portions for connecting to the first straight portion and the second straight portion.

Abstract
An air bag provided with linear joined portions in the inflation section is disclosed. The linear joined portions linearly join the opposing wall portions of the inflation section. Each of the linear joined portions includes a body portion and end portions. The end portions extend from the body portion and gradually become wider than the body portion. The periphery surrounds the end portions and is provided with at least three straight portions. This air bag restrains mesh spreading and inflating gas leakage from the vicinity of any of the end portions of the linear joined portions.
