PURPOSE: To stably support a spherical bearing and to prevent an abnormal sound from generating by forming a spherical part at the center of an annular leaf spring for holding the bearing, and surface-contacting the part with the spherical band of the bearing.
CONSTITUTION: When a spherical bearing member 5 is held fixedly by an end bracket 6 and an annular leaf spring member 8, the periphery of the central hole 8a of the member 8 is formed as a spherical part 8b. The periphery of the member 8 is formed as a flange-like flat part 8c. The spherical part 8b of the member 8 is surface-contacted with the spherical band of the member 5, the flat part 8c is brought into contact with the bracket 6 to fix the member 5. Thus, the member 5 can be secured stably and rigidly to prevent a noise from generating.
