The fixing member includes a cover portion covering a shaft lower end portion located at an axially lower end of the shaft when viewed from axially below. The cover portion has an opening portion that opens in an axial direction. The opening portion is located radially more inside than an inner peripheral surface of the shaft when viewed from axially below.
