Problems solved by technology

Therefore, the movement of the wire harness in the direction along the rotation axis of the motor or in the circumferential direction of the fan casing cannot be completely suppressed, and the wire harness may deviate or come off from the holding portion.
Such a problem is not limited to the fan for vehicles, but is a common problem when the fan needs to be installed in a limited installation space.

Abstract

The fan includes: a motor; an impeller, which is fixed to the rotating shaft of the motor; a fan casing, which is used to accommodate the motor and the impeller, and has an air passage formed inside; a wire harness, which extends from the inside of the fan casing to the outside; and a holding portion for holding the wire harness. The holding part includes: a rib protrudingly formed on the peripheral wall of the fan housing; the other side. In addition, the wire harness is locked by the locking piece on the one end side and the locking piece on the other end side so as to be twisted via the rib.

Description

Technical field [0001] The present invention relates to a fan comprising: an electric motor; an impeller, which is fixed to the axis of rotation of the motor; a fan shell for housing an electric motor and an impeller; and a holding portion for maintaining a self-air housing extends The harness. Background technique [0002] A battery, which is stored in a mixed power vehicle, or the like, is generated from the battery to an inverter circuit such as an alternating power to travel to the traveling motor or the like. Further, in order to deliver such a device to deliver such a device, a fan is mounted in such a car. [0003] For the fan in which the vehicle is carried, it is not only necessary to compact the wind housing in advance setup space, but also the power supply and signal transmission of the electric motor connected to the fan and the back surface of the self-winding case. A fully set mount space is included in the mainland. [0004] As disclosed in Patent Document 1, it is...
