Abstract

- Problems: To provide a seal structure that keeps a needle from sliding with respect to a seal and is easily detachable, and a device having the seal structure. Solution: A seal through which a needle of a valve device is to be inserted, the valve 5 device including a fluid chamber having an outflow hole and an inflow hole, and the needle of which fore end reciprocates in the fluid chamber, the seal including a main body made of an elastic body having a needle fitting insertion hole formed for the needle to be inserted and fit into, and a flange portion made of an elastic body annularly extending from the main body in a radial direction outward, wherein one end opening 10 diameter (D3) of the needle fitting insertion hole is smaller than the other end opening diameter (D2) of the needle fitting insertion hole, a seal structure including that seal, and a device including that seal structure.
