Abstract: A power supply device (1) includes a battery cell assembly (2) being an assembly of battery cells (3) each having electrodes (4) and a battery connecting block (10) including a case body (11) including an adjacent first and second divided fixing portions (12, 13) connected to each other via a flexural deformation portion (14). The flexural deformation portion (14) includes a first rising linear portion (40) having one end fixed to the first divided fixing portion, a second rising linear portion (40) having one end fixed to the second divided fixing portion, first and second curve portions (41) bent at the other ends of the first and second rising linear portions (40) in a direction to come close to each other, and a linear portion (42) connecting the first and second curve portions to each other.

Abstract: A terminal fixation structure includes a terminal fixing portion including a terminal housing chamber, a terminal including a positioning recessed portion and housed in the terminal housing chamber, and a positioning rib provided in a center of the terminal fixing portion to protrude into the terminal housing chamber and fitted into the positioning recessed portion.

Abstract: A power supply device includes a battery cell assembly being an assembly of battery cells each having electrodes, a battery connecting block including a case body including terminal fixing portions connected to each other via flexural deformation portions and a cover fixed to the case body and configured to cover the terminal fixing portions, and lock portions provided to the cover and the case body with intervals in a longitudinal direction. A lock portion other than lock portions located at two end positions in the longitudinal direction is configured to be capable of locking the cover with the case body with a changeable relative lock position of the cover and the case body in the longitudinal direction.

Abstract: Abnormal noise at a battery pack busbar module is prevented. A battery pack busbar module includes busbar accommodating portions each accommodate busbars which connect in series batteries, cover portions coupled by hinges to one of side edges of openings in the busbar accommodating portions to cover the openings, and lock portions to lock the cover portions by bringing first engagement portions provided on the other side edges of the busbar accommodating portions and second engagement portions provided on the cover portions into engagement with each other, and ribs projecting from the cover portions to come into abutment with the busbar accommodating portions are formed in positions spaced away from the lock portions, a height of the ribs being set such that the second engagement portions are not brought into engagement with the first engagement portions when the ribs abut the busbar accommodating portions.

Abstract: A synthetic resin plate (1) includes a plurality of accommodating parts (2) which accommodate at least one of bus bars, terminals, and electric wires which are connected to the terminals, hinges (7) which make first accommodating parts and second accommodating parts of the accommodating parts (2) connected and relatively movable, and projecting parts which are provided on the top surfaces of peripheral wall parts of the first accommodating parts, and which abut against parts of the second accommodating parts to restrict the movable ranges in the movable directions of the second accommodating parts relative to the first accommodating pans.

Abstract: Attaching work of a high-voltage cable is improved. In an electric cable connecting construction of battery packs, the high-voltage cable is connected to conductors held in resin busbar modules for connection with the general electrodes by fastening crimp terminals to the conductors. Two ribs are formed on each of the busbar modules where the crimp terminal is held therebetween to limit an entrained rotation of the crimp terminal. A difference between a gap of the two ribs on one of the adjacent battery packs and a width of the crimp terminal connected to the general electrode is set to a first gap dimension L3 and A difference between a gap and a width of the crimp terminal connected to the general electrode of the other of the adjacent battery packs is set to a second gap dimension L6 larger than the first gap dimension.

Abstract: A drawing section 35 for electric wires 17 is formed such that a bottom plate 37 and a side wall 39 of a wiring path 21 are extended to be projected from an insulating plate 23. A tongue piece 43 around which a tape is wound together with the wires 17, is formed on the drawing section 35. The tongue piece 43 is bent in a direction opposite to a rising direction of the side wall 39 of the drawing section 35 so that a projection dimension of the tongue piece 43 is reduced.

Abstract: A rotational angle detecting device includes a rotary shaft 1 having an annular projection 1c formed therein so as to extend radially outwardly therefrom, and a housing 2 rotatably supporting the rotary shaft 1. A plurality of rolling contact bearings 6 each having inner and outer races are mounted on the rotary shaft 1 under a pre-loaded condition so as to sandwich the annular projection 1 c between the respective inner races of the rolling contact bearings 6. The assembly is rotatably received inside the housing 2 to permit the rotary shaft 1 to be rotatable about a longitudinal axis thereof. A resistor element 12 is disposed on an inner surface of a housing lid 3 in concentric relation to the longitudinal axis of the rotary shaft 1. An electroconductive brush 5 is secured to an end face of the rotary shaft 1 for rotation together with the rotary shaft 1 and held in sliding contact with the resistor element 12.
