The fixing structure includes an installation portion having an installation hole into which an installation bolt provided in a chassis is inserted, and a spacer supported movably in horizontal directions perpendicular to an axial direction of the installation bolt inside the installation portion in a non-fastened state between the installation bolt and the nut. The spacer has a collar portion that is placed between an inner circumferential surface of the installation hole and an outer circumferential surface of the installation bolt and makes contact with the chassis and the washer in the axial direction of the installation bolt in a fastened state between the installation bolt and the nut, and a flange portion formed to protrude outward from the outer circumference of the collar portion and supported movably in the horizontal directions in a non-fastened state. The flange portion is fixed inside the installation portion in the fastened state.

A fixing structure includes an attaching portion, a nut, and a spacer. The attaching portion has an attaching hole through which an attaching bolt provided to a vehicle body is inserted. The nut fixes the attaching portion to the vehicle body by being tightened to the attaching bolt with a washer interposed between the nut and the attaching portion. The spacer is disposed between an inner circumferential surface of the attaching hole and an outer circumferential surface of the attaching bolt, and is in contact with the vehicle body and the washer in an axial direction of the attaching bolt in a state where the attaching bolt and the nut are tightened. The spacer has an opening on a cylindrical side surface thereof and is capable of rotating around the axial direction of the attaching bolt in a state where the attaching bolt is inserted into the opening.

An attachment structureincludes: a plurality of attaching legsprojected from an outer surface of a box main bodyas the object and overlapped with a vehicle attaching portionas the subject; a washerfixed to the vehicle attaching portiontogether with one attaching legby a bolt, while being overlapped with the one attaching legat a side away from the vehicle attaching portion; and a coverattached to the one attaching leg, holding the washerbetween the coverand the one attaching leg. The coveris provided with an exposing holefor exposing a first hole portionprovided on the washer

A hole for inserting a binding band is arranged through a gutter shape electric wire passing guide. A widening width guide groove for guiding the binding band is arranged at an inner surface of the electric wire passing guide so as to expand its width gradually from the hole toward an opening end of one sidewall of the electric wire passing guide. In condition that a plurality of electric wires is inserted in the electric wire passing guide, a tip end of the binding band is inserted from the guide groove into the hole. One side surface of the guide groove is curved convexly toward the projecting top between the hole and the opening end. The one side surface of the guide groove is inclined toward the projecting top between a bottom surface of the guide groove and the inner surface of the electric wire passing guide.

The present invention provides a bracket configuration for retaining a washer within a washer case which has an opening for inserting the bracket therethrough so that the washer case is mounted to the bracket from above the washer. The bracket configuration specifically includes a hole configured to dispose the washer thereon and insert a bolt therethrough, and a rib formed along an edge of the opening so as to prevent or protect the washer from deviation or disconnection via a clearance gap created between the opening and the bracket.

Washer-retaining bracket configuration

There is provided a junction box unit that comprises a body to which a power integration unit is attached and a connector cover that positions a connector of a wiring harness with respect to the body. The connector cover comprises a holding portion holding the connector, a mounting portion attached to the body, and a main body to be accommodated therein. The mounting portion comprises an engagement projection and an engagement arm. The engagement projection protrudes from one end of the main body for locking engagement with a locking portion of the junction box body. The engagement arm includes an arm main body having one end continuing to an outer surface of the other end of the main body and a free end. A protrusion is provided at the central portion of the arm main body for locking engagement with the locking portion. When the protrusion is in locking engagement with the locking portion, the other end of the arm main body is positioned more outwardly of the body than the locking portion.

Connector cover and junction box unit provided with the same

When a predetermined rupture load is applied to a mounting bracket formed on an attachment part, a rupture develops in the mounting bracket, and the attachment part can be separated from a base part by this rupture. The mounting bracket, in which a slit extending in a direction intersecting a loading direction of a rupture load is formed, includes a rigid portion disposed at one side of the slit and a breakable portion disposed at the other side of the slit which is breakable because of the presence of the bolt.
