Connection means for cooling fan assemblies are used to connect the fan assemblies to drive means such as viscous fluid couplings. The connection means includes a generally annular plate spring which has projections extending radially inward of an annular base and tongues projecting radially inwardly from the base. Each of the tongues is provided with a circumferential extension axially deformable and at the tip with an enlarged portion. The enlarged tip portions are secured to a casing of the drive means and the projections and the tongues are secured to a boss of the fan assembly with bolts. The arrangement that the projections, the tongues and the circumferential extensions are disposed inside of the base and the projections and the tongues are secured to the fan assembly serves to decrease vibration of the fan assembly and to increase the durability of the connection means. |
