Abstract: Provided is an electrical connection unit disposed in an automobile and performing relay in supplying electrical power from a first power source to a load apparatus. An electrical connection unit includes: a first electrical power path and a second electrical power path connected to a load apparatus; a third electrical power path connected to a first power source; a power source connection part which can be connected to a second power source; a first fuse attachment part which can attach a first fuse connecting the first electrical power path and the third electrical power path and is connected to the first electrical power path and the third electrical power path; and a second fuse attachment part which can attach a second fuse connecting the second electrical power path and the third electrical power path and is connected to the second electrical power path and the third electrical power path.

Abstract: A grommet includes a bellows portion and a movable-member-side fitting portion connected with an end of the bellows portion. The movable-member-side fitting portion has an outer surface connected with the bellows portion and an inner surface formed on the opposite side of the outer surface. On the outer surface, the bellows portion is connected to the movable-member-side fitting portion with unequal distances from an axial center of the bellows portion to the outer edge of the movable-member-side fitting portion. Furthermore, on the outer surface, a first outer rib is formed that extends along a direction having a maximum distance from the axial center to the outer edge with an outer peripheral surface of the bellows portion serving as its base.
