型フロントフオーク。[Claims for Utility Model Registration] (1) In a front fork mechanism with a built-in damper, a valve mechanism installed between the upper part of the cylinder and the inner wall of the inner tube forms a separated pressure chamber, and the valve mechanism is connected to the front fork mechanism. It consists of a check valve that opens when the fork is extended, and an oil hole that generates a damping force when it is compressed, and is located between the main suspension spring and the detection spring, which are arranged in series in the compression side movement area of the inner tube. A front fork with a built-in damper, characterized in that the opening area of the oil hole is variably controlled by the relative displacement of the facing detection member with respect to the valve mechanism. (2) Utility model registration claim 1, which is obtained by adding a valve to the valve mechanism that opens against the energizing force when the front fork is compressed.
Front fork with built-in damper as described in section. (3) The valve mechanism includes a valve that opens against the energizing spring force when the front fork is compressed, and the energizing spring of the valve is arranged in a position mechanically parallel to the detection spring. A front fork with a built-in damper according to claim 1 of the utility model registration claim.
