A worm reduction gear satisfies following relational Formula (1) and Formula (2):
3D2/D11.7(1)
0.10.5(2)
where D1 is an outside diameter of a worm, D2 is an outside diameter of a hob for cutting a worm wheel to form tooth spaces, and is a pressure angle of the worm wheel and is a pressure angle of the worm at an intermeshing pitch circle of the worm and the worm wheel.

The present disclosure relates to a vehicle steering apparatus, the vehicle steering apparatus includes a main housing; a worm shaft rotatably disposed on the main housing; a worm wheel meshed with the worm shaft; a bearing disposed on the worm shaft; an elastically deformable guide surrounding an outer surface of the bearing and disposed within the main housing; and a pressing part extending through the elastically deformable guide to be in contact with the bearing and configured to press the worm shaft toward the worm wheel.

A portable storage device to contain fuel, The device is designed to be relatively light-weight to allow for movement around a fueling facility, and to be delivered to the fueling facility through the air. The device includes a number of separate tanks each configured to contain fuel. A suspension protects the tanks by absorbing external forces that could occur in the event the device is dropped during air delivery.

The present invention is related to a reducer of an electric power steering apparatus. An embodiment of the present invention provides a reducer of an electric power steering device. The reducer includes: a worm shaft having a worm formed thereon; a worm wheel having a worm gear formed thereon to be engaged with the worm; and a clearance compensation device coupled to a worm shaft bearing provided on an end of the worm shaft and configured to elastically support the end of the worm shaft within a reducer housing.
