A heater module is configured to be arranged on a side surface of a battery module and includes: a heat equalizing plate; a heater, a heater cover; and a metal stay in this order from the side surface of the battery module. The heater is fixed on the heat equalizing plate, the heater cover includes a heat equalizing plate holding portion and a stay holding portion, the metal stay includes: fastening portions provided on both end portions thereof in a stacking direction of cells and configured to be fastened to the side surface of the battery module; and a bent portion configured to cover a lower surface of the heater cover, and the bent portion of the metal stay is arranged at a location overlapping with the heat equalizing plate holding portion of the heater cover in the stacking direction.

Heater module

A vehicle power source system includes a plurality of module groups each including a plurality of battery modules and disposed separately from each other, and a cooling circuit including a plurality of module group cooling units which are configured to respectively cool the plurality of module groups. The plurality of module group cooling units are connected in series. Each of the plurality of module group cooling units includes a plurality of module cooling units, each of which is configured to cool one or more of the battery modules. In each of the plurality of module group cooling units, the plurality of module cooling units are connected in parallel.

Vehicle power source system

A vehicle includes an electric device, a cover which is configured to cover the electric device, and a cooling circuit which is configured to cool the electric device with a refrigerant. An air-venting member is provided in the cooling circuit. A cover through portion is provided in the cover. The air-venting member is disposed to the cover through portion from an inner side of the cover and is configured such that an air discharging operation is performed from an outer side of the cover.

To connect a bus bar plate to a battery module, a plurality of recess portions provided on a plurality of holders so as to be spaced in the stacking direction are engaged with a plurality of projection portions provided on the bus bar plate to be spaced in the stacking direction. Since the lengths 'a' of the plurality of projection portions are the same, and the plurality of recess portions are formed from a first recess portion having a length 'a' and a second recess portion having a length &#x201c;b&#x201d; larger than the length &#x201c;a,&#x201d; the precision of positioning of the bus bar plate can be ensured by engagement between the projecting portion and the first recess portion, and even if the gap between the projecting portions or the recess portions is nonuniform, it is possible to assemble the bus bar plate onto the holder with high precision.

A propeller shaft PScomprises a front pipe memberand first and second yoke membersand, which are attached to both the ends of the front pipe member. The first yoke memberis attached by press-fitting a first yoke fitting portioninto the inner circumferential part at the left end of the front pipe memberuntil the front end of the front pipe member comes near a stopper portion. The second yoke member, which has no stopper portion, is attached by press-fitting a second yoke fitting portioninto the inner circumferential part at the right end of the front pipe member. When a compressive force greater than a predetermined force acts axially, while the first yoke fitting portionis prevented from being further inserted by the stopper portion, the second yoke fitting portionis press-fit further into the inner circumferential part of the front pipe member, which is thereby expanded and destroyed.

Propeller shaft and rotational power transmission mechanism equipped with this

A paper tube of a propeller tubeis made by winding a single faced corrugated fiberboardin which a wavy corrugating mediumis fixed to one side of a flat linerboardso that the corrugating mediumis oriented outwards, and the corrugating mediumcontacts with an inner surface of the propeller tubeso as to enhance a vibration controlling function. When winding the single faced corrugated fiberboardsince the single faced corrugated fiberboardcannot be wound in a direction oblique to a direction of ridges of the corrugating mediumthere are no fears that the shape of the single faced corrugated fiberboardis collapsed to taper axially, thereby it becomes possible to prevent a reduction in vibration controlling function that would otherwise be caused due to a change in the shape of the paper tube.
