The invention provides a fixing member and an image forming apparatus. The fixing tool includes a screw member and a ring-shaped spacer member. The screw member includes a base, a protrusion protruding from the base, and a screw portion at the tip of the protrusion. The spacer member is mounted on the protrusion in such a manner as to freely slide between the base and the screw. The first part is clamped by the base and spacer parts. The second part is sandwiched by the nut part and the spacer part, the nut part is screwed on the screw part, and the second part is a different part from the first part.

To provide a quick connector capable of surely confirming that a pipe body is engaged by a retainer when an elastically-deformable claw of the retainer and an elastically-deformable claw of a checker are adjacently arranged in an axial direction. Checker-axis direction elastically-deformable claws 52 and 52 have distal-end sides formed flexibly deformable in the axial direction, maintain a state of being engaged by a second engagement portion 46 of a retainer body 42 by having deflective deformation regulated by a retainer diameter-expanding elastically-deformable claw 49 in a state in which the retainer diameter-expanding elastically-deformable claw 49 is expanded diametrically, and regulate sliding from a first position with respect to the retainer body 42 toward a set radial direction by being engaged by the second engagement portion 46 of the retainer body 42. The checker-axis direction elastically-deformable claws 52 and 52 become releasable from engagement with the second engagement portion 46 of the retainer body 42 in a state in which the retainer diameter-expanding elastically-deformable claw 49 has restored its original shape, and thereby become slidable with respect to the retainer body 42 from the first position toward the second position in the set radial direction.

The invention discloses a tool holder for grooving a cutting blade. The tool holder comprises a tool holder body and a fastener, a clamping portion of the tool holder body consists of an upper clamping portion and a lower supporting portion, an upper positioning surface of the upper clamping portion and a lower positioning surface of the lower supporting portion enclose a blade clamping groove, a rear supporting surface and an elastic extending section are arranged at the rear end of the blade clamping groove, the elastic extending section extends backwards to the neck of the tool holder body, the fastener penetrates through the upper portion and the lower portion of the elastic extending section, M discontinuous upper positioning tables are arranged on the upper positioning surface, and N discontinuous lower positioning tables are arranged on the lower positioning surface, wherein 2<=M<=6, and 2<=N<=6. The tool holder for grooving the cutting blade has the advantages that positioning positions and angles can be automatically adjusted, plastic deformation of the tool body can be effectively suppressed, and the tool holder is stable in structure and long in service life.

Provided is an accumulator, which: is capable of reducing the pressure difference that is generated by differences in coefficients of thermal expansion when liquid trapped in the liquid chamber and a sealed gas undergo thermal expansion during zero-down, thereby limiting the occurrence of plastic deformation in the bellows; and has a structure in which the parts are small and few in number. To achieve said purpose, the accumulator has a sealing member held on the port hole-side of the bellows cap via a seal holder. When operation of the machine is stopped and the pressure inside the pressure piping decreases, the sealing member contacts the sealing section and closes the liquid chamber. If liquid trapped in the liquid chamber when the liquid chamber is closed undergoes thermal expansion, the bellows cap moves in the direction away from the sealing section while the sealing member is still in contact with the sealing section. Since the sealing member is a rigid plate, the outer circumferential surface of which is covered by a flexible section obtained from a rubber-like elastic body, the flexible section allows relative movement of the bellows cap by undergoing shear deformation as a result of engagement with the seal holder.
