PURPOSE:To obtain a shaft support excellent in impact characteristics by providing a semi-setback step part at a fixing hole made through the chassis in order to outsert a shaft support and making a plurality of holes for reinforcing the shaft support on the periphery of the fixing hole in the outsert region. CONSTITUTION:In order to use a part of chassis 11 as the motor housing, a shaft support 2 for securing the rotary shaft 14 of motor is outserted over a fixing hole 11a made through semi-setback of the chassis 11 on the rear side thereof thus making the rear side of the chassis 11 flush with the bottom face 2a of the shaft support 2. Four or eight reinforcing through holes 35 are made at a constant interval around the fixing hole 11a simultaneously therewith and the chassis 11 is subjected to semi-setback at a position including one half of the reinforcing hole 35. The shaft support 2 is then outserted and the reinforcing hole 35 is filled with molding resin for the shaft support 2 thus securing the shaft support 2 rigidly to the chassis 11. |
