Definitions

  • the upper wall portion 14 of the upper Z1 of the cell accommodating portion 13 consists of four arcuate walls continuous in the width direction. That is, the upper wall portion 14 extends along the outer peripheral surfaces of the four cylindrical cells 2.
  • the lower wall portion 15 of the lower Z2 of the cell accommodating portion 13 is linear in the width direction. Therefore, a space is provided between the cylindrical cell 2 and the lower wall portion 15 in which the embedded member 30 is placed.
  • the upper member 46 is provided with three convex portions 47 that protrude upward Z1.
  • the three convex portions 47 are arranged between two adjacent cylindrical cells 2. That is, the container 40 includes a first convex portion 41 disposed between the first cylindrical cell 2a and the second cylindrical cell 2b, and a second convex portion 41 disposed between the second cylindrical cell 2b and the third cylindrical cell 2c. A convex portion 42 and a third convex portion 43 disposed between the third cylindrical cell 2c and the fourth cylindrical cell 2d are provided. Further, the first convex portion 41, the second convex portion 42, and the third convex portion 43 each have a continuous internal space.
  • the first convex part 41 will be explained as a representative example, and the explanation of the second convex part 42 and the third convex part 43 will be omitted.
  • the gas storage section 60 includes an end 51b of the first arc wall 51 closer to the connection section 53, an end 52b of the second arc wall 52 closer to the connection section 53, and a connection section 53. ing. Therefore, the gas storage section 60 is in contact with each of the two adjacent cylindrical cells 2 (the first cylindrical cell 2a and the second cylindrical cell 2b).
  • a portion of the first arcuate wall 51 excluding the end portion 51b (a portion constituting the endothermic agent accommodating portion 61) will be referred to as an endothermic agent wall portion 51c.
  • the gas storage section 60 of the present disclosure is provided on the inner surface of the wall portion (the end 51b of the first arc wall 51, the end 52b of the second arc wall 52, and the connection section 53) that constitute the gas storage section 60.
  • the gas storage section 60 also includes a case where the heat absorbing agent 7 is attached to the inner surface of the wall that constitutes the gas storage section 60 .
  • the gas 8 accommodated in the gas containing section 60 comes into contact with the inner surface of the wall forming the gas containing section 60 due to the heat absorbing agent 7 attached to the inner surface of the wall forming the gas containing section 60.
  • the fourth gas storage section 164 is arranged between two vertically adjacent cylindrical cells 2 that are arranged in the second width direction Y2 among the four cylindrical cells 2 . From the above, according to the second embodiment, it is also possible to suppress the explosion of two vertically adjacent cylindrical cells 2.
