Abstract
An improvement of an output shaft of a booster is disclosed. An output shaft 23 is formed by a push rod 24 and an adjusting screw 25. The push rod 24 is formed with an axial bore 26 in its distal end, the axial bore including a portion 26b of a reduced diameter which is less than an outer diameter of a threaded section 25C of the adjusting screw. The threaded portion is formed as a self-tapping screw. The adjusting screw includes a guide 25D at a location which is initially inserted into the axial bore before the threaded portion is inserted into the threaded portion. The guide comprises a plurality of annular projections 27 having an outer diameter which is substantially equal to the inner diameter of the axial bore. With this construction, when the guide 25D is fitted into the portion 26b of the axial bore 26 which has a reduced diameter, the axis of the adjusting screw 25 may be brought into alignment with the axis of the push rode 24. Under this condition, the threaded section 25C may be threadably engaged with the inner periphery surface of the axial bore, thus preventing a misalignment of the adjusting screw.
