Abstract (en)
To provide a spindle device for driving a single spindle which is capable of preventing the vibration of a bolster from being directly transferred to a motor housing and in which it is easy to incorporate a buffer member. A spindle device (1) for driving a single spindle is provided with a rotor (6) and a stator (9). The rotor (6) is fixed to a spindle (4) in a manner that allows the rotor (6) to rotate together with the spindle (4) that is rotatably supported in a bolster (2). The stator (9) is fixed inside a motor housing (8) supported on a spindle rail (7). A buffer member (10) having a damper effect is placed between a housing (2a) of the bolster (2) and the motor housing (8) such that the buffer member (10) is fixed to a motor housing attaching portion (13) and a bolster attaching portion (14) only on its laterally extending faces. The buffer member (10) is fixed to the attaching portions (13 and 14) by thermal fusion. The buffer member (10) is shaped into a ring and placed such that it is sandwiched between the attaching portions (13 and 14). <IMAGE>
