Document Type and Number:
WIPO Patent Application WO/2018/225636
Kind Code:
A1
Abstract:
A buffer member is an elastically deformable tubular body provided between a case (5) that accommodates an air-blowing fan (6) and a motor device (2) that rotatably drives the air-blowing fan, wherein, together with a fixing tool (4) in which a shaft part (42) is inserted through the case and fixed, the buffer member links the case and the motor device together. The buffer member comprises: support portions (31, 32) that are located on both axial-direction sides of the tubular body, and that come into contact directly or indirectly with the shaft part once the shaft part has been inserted; and an intermediate portion (33) that is located axially between the support portions in the tubular body, and that has an inside diameter larger than the support portions. The intermediate portion includes a contact part (34) that moves apart from the shaft part and comes into contact with the motor device on the outer periphery to support the motor device.
