摘要： An end plate (42) includes a plate-shaped member (100). The plate-shaped member (100) has an uneven shape including an abutment portion (110A, 110B) and a recess (120), the abutment portion (110A, 110B) being in abutment with the stack in a first direction, the recess (120) being located in a direction away from the stack with respect to the abutment portion (110A, 110B). The recess (120) includes a first portion (150) and a second portion (151), the first portion (150) having a flat surface shape, the first portion (150) constituting a bottom surface of the recess, the second portion (151) having been through a process for forming the uneven shape. A pressing process has been performed onto the plate-shaped member (100) at a region overlapping with the second portion when viewed in the first direction so as to form a flat surface (150A) continuous to the first portion (150).

摘要： A battery module includes: a duct (71) through which gas discharged from the battery cell flows; and an attachment-target member (30) to which the duct (71) is attached. The attachment-target member (30) has a first wall portion (116) and the duct (71) has a second wall portion (131). The first wall portion (116) is provided with a claw portion (121). The second wall portion (131) is provided with a groove portion (161). The groove portion (161) includes a first segment portion (166) and a second segment portion (167), the first segment portion (166) extending in the Y axis direction, the claw portion (121) being disposed in the first segment portion (166), the first segment portion (166) anchoring the claw portion (121) in the Z axis direction, the second segment portion (167) being opened at an end portion of the duct side wall portion (131) in the Z axis direction, the second segment portion (167) extending in a direction intersecting the Y axis direction, the second segment portion (167) being connected to the first segment portion (166), the second segment portion (167) allowing the claw portion (121) to enter the first segment portion (166) when attaching the duct (71) to the attachment-target member (30).

摘要： A battery module (100) includes: a plurality of battery cells (11) arranged side by side in a first direction, each of the plurality of battery cells (11) having a prismatic shape; two restraint members (43) that each restrain the plurality of battery cells (11) along the first direction, each of the two restraint members (43) being provided to be arranged side by side with the plurality of battery cells (11) in a second direction orthogonal to the first direction; and a coupling member (91) in a form of a strip, the coupling member (91) extending in the second direction at an intermediate portion in the first direction to couple the two restraint members (43) to each other. The coupling member (91) has a first engagement portion (93T) and a second engagement portion (93S) that are respectively engaged with the two restraint members (43) in directions of sandwiching the two restraint members (43) along the second direction.

摘要： A battery module (100) includes: a plurality of battery cells (11) stacked in a Y axis direction; a cover body (51) that covers the plurality of battery cells (11) in a Z axis direction; and a duct (71) through which gas from each of the plurality of battery cells (11) flows. The duct (71) has: a duct main body portion that forms a flow space for the gas; a cylindrical portion (73) to which a hose can be fitted, the cylindrical portion (73) extending, in the Y axis direction in a form of in a cylinder, from one end portion of the duct main body portion in the Y axis direction so as to have a tip with an opening; and a projection (271) with which an end portion of the hose fitted to the cylindrical portion (73) can be brought into abutment, the projection (271) protruding from an outer peripheral surface of the cylindrical portion (73) at a position away from the opening of the cylindrical portion (73) in the Y axis direction. The cover body (51) has an anchoring portion (241) anchored to the projection (271) in the Z axis direction.
