The present invention provides a splinter shield for a vacuum pump, capable of reducing costs of the splinter shield by obtaining a single sheet of splinter shield having a required strength, in which fastening strength to a fixing groove is enhanced to prevent the splinter shield from bending toward the inside of a pump and coming into contact with equipment inside the pump when air rushes into the pump through an inlet port and to prevent the splinter shield from falling. Furthermore, attachment and removal of the splinter shield with respect to the inlet port are facilitated.The present invention is a splinter shield for a vacuum pump in which a rim formed in a circumferential edge portion of the splinter shield is inserted into a fixing groove that is provided in a concave manner in an inner circumferential portion of an inlet port, and the splinter shield is provided in a tensioned manner to the inlet port by pushing a retaining ring into the fixing groove, wherein locking parts that are locked into the retaining ring at a plurality of sections in the rim are provided in a standing manner at substantially right angles to the rim.

A car seat fabric is simulated with a feeling of reality. A fabric texture information input acceptance portion (101) accepts texture information about the fabric used for the car seat fabric. A thread information input acceptance portion (102) accepts thread information about threads used for the fabric. A 3-D fabric image creation portion (103) creates a steric structure of the car seat fabric as a 3-D fabric image on the basis of the texture information accepted at the fabric texture information input acceptance portion (101) and the thread information accepted at the thread information input acceptance portion (102). An image attachment portion (105) attaches the 3-D fabric image created by the 3-D fabric image creation portion (103) to a car seat model. A car seat image display (402) displays the car seat model to which the 3-D fabric image is attached by the image attachment portion (105).

Provided are a terminal structure capable of preventing damage due to an excessive force and having high sealing property, and a vacuum pump to which the terminal structure is applied. When a control device (400) undergoes transition to a turbo molecular pump main body (300), a cylindrical wall (603) of a female connector (600) is fit-engaged with a cavity (504) of a male connector (500). As the connection progresses, head portions (511a) at one ends of male pins (511) are inserted into pin insertion elongated holes (624). When, after that, a forward end of the cylindrical wall (603) of the control device (400) abuts a bottom portion (501) of the female connector (600), the female connector (600) on the control device (400) side, which is of low rigidity, is pushed back against an elastic force of waved washers (613). As a result, even when an excessive force is applied to the female connector (600) and the male connector (500), the force can be mitigated through deformation of the waved washers (613), so there is no fear of the connectors suffering damage.

A molecular pump has a casing having a gas inlet port and a gas discharge port, a stator disposed within the casing, a shaft disposed in the casing concentrically with the stator, a bearing rotatably supporting the shaft for undergoing rotation relative to the stator in a preselected direction of rotation, a rotor mounted on the shaft for rotation therewith in the preselected direction of rotation, and a motor for rotationally driving the shaft. A flange is connected to the casing at the gas inlet port. The flange has at least one mounting hole for receiving a fastener, a first elongated through-hole disposed in communication with the mounting hole, and a second elongated through-hole spaced apart from the first elongated through-hole in a direction toward a direction of rotation opposite to the preselected direction of rotation to define between the first and second elongated through-holes a deformable thin-wall portion for undergoing deformation due to a shock resulting from a torque acting on the casing in the preselected direction of rotation.
