A diaphragm unit detachably attached to a damper body, comprising:
- a cylinder in which a liquid is sealed;
- a piston rod having a piston sliding inside the cylinder on one end side of the piston rod, in which other end side of the piston rod is extended to an outside of the cylinder;
- and a rod guide having a bottomed cylindrical shape wherein an insertion opening into which the piston rod is inserted is provided at a bottom portion of the rod guide, the rod guide being fixed to a side of an opening of the cylinder into which the piston is inserted to thereby make the piston rod be slidably inserted in a liquid tight manner, the diaphragm unit further comprising:
- an end member having a bottomed cylindrical shape wherein an insertion opening into which the piston rod is inserted is provided at a bottom portion of the end member, the end member being detachably fitted to an outer periphery of the cylinder or the rod guide so as to cover the opening of the cylinder or the rod guide;
- an air seal provided at an inner peripheral portion of the insertion opening of the end member;
- a rod side member having a bottomed cylindrical shape wherein an insertion opening into which the piston rod is inserted is provided at a bottom portion of the rod side member, the rod side member being provided in a position around the other end side of the piston rod;
- an annular bump rubber fixed to an inner bottom portion of the rod side member and having a through hole into which the piston rod is inserted;
- and
- a tubular diaphragm fixed to the end member at one end of the diaphragm and fixed to the rod side member at other end of the diaphragm.
A suspension comprising:
- a cylinder in which a liquid is sealed;
- a piston rod having a piston sliding inside the cylinder on one end side of the piston rod, in which other end side of the piston rod is extended to an outside of the cylinder;
- a rod guide having a bottomed cylindrical shape wherein an insertion opening into which the piston rod is inserted is provided at a bottom portion of the rod guide, the rod guide being fixed to a side of an opening of the cylinder into which the piston is inserted to thereby make the piston rod be slidably inserted in a liquid tight manner;
- an end member having a bottomed cylindrical shape wherein an insertion opening into which the piston rod is inserted is provided at a bottom portion of the end member, the end member being detachably fitted to an outer periphery of the cylinder or the rod guide so as to cover the opening of the cylinder or the rod guide;
- an air seal provided at an inner peripheral portion of the insertion opening of the end member;
- a rod side member having a bottomed cylindrical shape wherein an insertion opening into which the piston rod is inserted is provided at a bottom portion of the rod side member, the rod side member being provided in a position around the other end side of the piston rod;
- an annular bump rubber fixed to an inner bottom portion of the rod side member and having a through hole into which the piston rod is inserted;
- and
- a tubular diaphragm fixed to the end member at one end of the diaphragm and fixed to the rod side member at other end of the diaphragm to thereby form an air chamber around the cylinder and the piston rod.
