A connection module includes a FPC, bus bars connected to the FPC and connecting the electrode terminals of power storage elements that are adjacent to each other, and a resin protector holding the bus bars and the FPC. The FPC includes a FPC body member and a first deformable portion that connects the FPC body member and the bus bars. The resin protector includes a FPC holding portion to which the FPC body member is fixed, movable bus bar holding portions to which the bus bars are fixed, respectively, and second deformable portions that connect the FPC holding portion and the movable bus bar holding portions. The first deformable portion and the second deformable portion connect the bus bars and the movable bus bar holding portions to the FPC body member and the FPC holding portion, respectively, such that the bus bars and the movable bus bar holding portions are movable with respect to the FPC body member and the FPC holding portion.

Connection module

A lock mechanism includes: a lock portion that protrudes from a ceiling wall (wall portion) of a cover and has a locking claw provided on a tip side; a lock receiving portion provided in a case and formed with a locking hole; and a flexible deformation portion which is a portion of a predetermined range in the vicinity of the lock portion on the ceiling wall (wall portion) of the cover and has flexibility higher than a portion outside the predetermined range, and is bent such that the lock portion is tilted so that the locking claw gets over an edge of the locking hole when the locking claw is locked to the locking hole, and after the locking, biases the lock portion in a pulling direction that pulls the locking claw together with the locking hole by a restoring force of bending.

Lock mechanism and bus bar module

A power supply apparatus that can achieve preferable holding and fixing of components constituting the power supply apparatus and can preferably prevent a liquid short-circuit and a leakage of current due to condensed water. The power supply apparatus includes a power supply unit having a plurality of power supply elements stacked with each other, an upper case and a lower case which house the power supply unit. The power supply further includes an auxiliary fastening portion which is fixed to the lower case and provides a space S between a lower surface of the power supply unit and the lower case, and fastening portions that are placed on the left and right of the power supply unit when viewed in a direction in which the power supply elements are stacked. The fastening portions fastening the power supply unit to the upper case.
