Abstract: An angle adjustment mechanism has a block, a projecting piece, and a connection mechanism. The projecting piece is fixed to a stator. The connection mechanism has elongated holes provided in the block and a shaft member provided in the projecting piece. The shaft member is inserted in the elongated holes. During a tilt angle adjustment process, the shaft member is caused to move in a sliding motion in the elongated holes. During a cooling process, the shaft member is also caused to move in a sliding motion in the elongated holes.
