Claims

[Claims for Utility Model Registration] (1) A rotation shaft of a blade plate rotatably provided within a casing, and an angle adjustment device provided outside the casing for adjusting the opening/closing angle of the blade plate. and are connected to each other via a shock absorbing device, the shock absorbing device having a prismatic inner shell rotatably fitted into a square tubular outer shell, and an outer shell on the outer periphery of the inner shell. The shock absorber is configured such that an elastic body is fitted into a space formed at an inner corner to give the inner shell a function of holding the outer shell in a fixed position around the central axis. Either one of the inner shell and the outer shell is fixed to one end of the rotating shaft, and the other of the inner shell and the outer shell is provided with a device for adjusting the angle of the blade plate in the angle adjusting device. A damper characterized by a fixed arm. (2) A shock absorber includes a spring set arm that is fixed to either the inner shell or the outer shell and is substantially parallel to the angle adjustment arm, and a spring set arm that protrudes from the angle adjustment arm and is attached to the spring set arm. Utility model registration claim No. 1 comprising a buffer adjustment device having a support piece facing the spring setting arm, and a bolt screwed onto the support piece and whose tip abuts against the spring setting arm.
