| 1. A drive guide apparatus having a linear motor and a guide mechanism that guides relative movement between a primary side
of said linear motor, which is an energized side thereof, and a secondary side of said linear motor, which is a non-energized
side thereof, and that carries a load, said guide mechanism having a rail and a moving member provided to be movable relative
to said rail,
wherein the primary side of said linear motor is connected to said moving member through a heatsink, and an absorbing member
is provided at a joint between said primary side and said moving member, said absorbing member being adapted to absorb a deformation
of said heatsink due to a thermal expansion difference between said moving member and said heatsink by shearing force deformation.
