A power transmission apparatus including a rotary unit (10) rotated by receiving the turning effort and a nut member (3) for coupling the rotary unit (10) to a rotary shaft (4) of a rotary device is disclosed. The nut member (3) has a central hole (3e) formed therethrough from one end surface (3c) to the other end surface (3d) thereof and an internally threaded portion (3g) formed in the central hole (3e). The internally threaded portion (3g) is forced onto an externally threaded portion (4b) formed on the rotary shaft (4) from the other end surface (3d) side thereby to be screwed to the rotary shaft (4) while at the same time coupling the rotary unit (10) to the rotary shaft (4). The apparatus further includes a cap (5) fitted onto the nut member (3) in such a manner as to cover and seal one end surface (3c) of the nut member and an outer peripheral surface (3i) of the nut member connected to the peripheral edge of the one end surface (3c).
A power transmission apparatus comprising:
A power transmission apparatus for transmitting the turning effort from a rotation drive source to the rotary shaft of a driven-side rotary device, comprising:
