The mounting structure for boosters to mount a booster provided with a casing formed by hermetically connecting a front cell and a rear cell includes a front bolt passing through the front cell, the inside of the front bolt being hollow, a tube having a cylindrical shape, the inside of which is hollow in the lengthwise direction, and provided with a front part being opposite the front bolt to communicate with the hollow of the front bolt and a rear part crossing the casing to pass through the rear cell, a support washer installed on the tube and connected to the rear portion of the front bolt to surround the outer circumferential surface of the rear portion of the front bolt, and a sealing member provided between the tube and the support washer. | 12-27-2012 |
20120322566 | REDUCER OF ELECTRIC POWER STEERING SYSTEM - The present invention relates to a reducer of an electric power steering system. By the system, it is possible to prevent a noise from being produced by a clearance between an inner rotor and an outer rotor. Further, since the steps of assembling the inner and outer rotors and applying grease are omitted, it is possible to simplify the assembling process of the reducer, to reduce the material costs, and to improve stability in assembling. | 12-20-2012 |
