Abstract: PROBLEM TO BE SOLVED: To reduce leak by improving seal effect of a seal, and reducing effects of deformation generated by action load on a seal member. SOLUTION: This roller assembly 58 includes a pin 78 having a tightening surface 130 to transmit force from the roller assembly 58 to a support part 86, and a collar 84 of a separate structure engaged with the tightening surface 130, extended in an axial direction to the support part 86 to part the tightening surface 130 from the support part 86, and disposed around the pin 78. The collar 84 has a first range 140 to be engaged with a shaft part 128 by compression force, and a second range 141 diametrically outwardly separated from the first range 140 in a diametrically outward direction from the shaft part 128. By using this collar 84, fatigue life of the roller assembly 58 can be elongated, and durability of the pin 78 can be improved.

Abstract: A clip member for a stator vane of a stator assembly of a rotary machine which has an installed condition in the rotary machine, the clip member (62) having: a base; and a retention member (84); wherein the retention member extends from the base and is spaced from the base leaving a gap there between which is adapted to receive the stator vane (28) and which adapts the clip member (62) to engage the stator vane (28) with the retention member (84) and the base; and wherein the retention member (84) is a spring member such that the retention member (84) presses the base against the stator vane (28) in the installed condition.
