Abstract:
A socket is attached to an end of one pipe and a plug is attached to an end of another pipe. The socket is provided with a pair of notched grooves at peripheral faces on both sides opposed to each other and a stopper constituting a U-shape is mounted onto the notched groove. The plug is provided with a first taper portion, a flat portion, and a second taper portion continuously from a front end side thereof in a sectional shape thereof along an axial direction, and a groove having the stopper inserted therein is formed at a ridge portion of the second taper portion. An inner periphery of the socket is arranged with a seal ring for sealing an interval between the inner periphery of the socket and an outer periphery of the plug in an airtight connection.
Abstract:
A string type air damper includes a cylinder formed in a tubular shape, defining a guide hole at one end portion thereof, a piston, which moves in the cylinder, a helical spring for biasing the piston toward the other end portion of the cylinder, and a string member guided from inside of the cylinder to outside thereof through the guide hole. The piston and the string member are integrally formed. Since the string member is formed integrally with the piston, unlike a method according to a related art, it becomes unnecessary to form a loop at the base end portion of the string member with a complicated work and form a hook portion at the piston and hook the base end portion of the string member at the hook portion of the piston. Therefore, the string type air damper can be very easily assembled.
Abstract:
A side lock apparatus includes: a housing which is fixed to a lid; a disc-shaped rotor which is supported on the housing; and rods which are linked with the rotor, wherein: the housing includes: a bearing portion for the rotor which is provided in such a manner as to extend vertically along the short upper portion of the lid; a first wall; a second wall; and a cylindrical portion which is brought into sliding contact with a disc-shaped outer circumferential surface of the rotor to support the rotor; the rotor is supported on the bearing portion in such a manner that the disc shape thereof becomes horizontal relative to a wall thickness direction of the short upper portion of the lid; and the rods are supported between the first wall and the second wall in such a manner as to slide in an opposite direction.
Abstract:
A connection structure or a fastening structure including a circuit which functions as a resonant circuit whose connection or fastening is confirmed by resonance of radio waves, the connection structure or a fastening structure has a connector for connecting a member to be connected or a clip for fastening a member to be fastened; a first circuit having first contacts on respective ends thereof; and a closed circuit functioning as a resonance circuit supported on the retainer or clip when in contact with the first contacts. Alternatively, the connection structure of fastening structure has a second circuit which disables a function of a resonance circuit upon contacting the first contact, and the first contacts and the second circuit are brought into contact simultaneously with connection of the connector or fastening of the clip.
Abstract:
A clip includes: a pin having a head and a shank; and a grommet having a collar and a leg. The leg of the grommet is divided into a plurality of expansion leg pieces by means of slits extending along an axial direction. The expansion leg pieces of the leg are expanded outwardly by the insertion of the pin into an inner side of the grommet, so as to clamp plate-like members by the collar and the expansion leg pieces. The leg of the grommet has resilient beams which project outwardly of the expansion leg pieces on a collar side when the pin is inserted into the inner side of the grommet.
Abstract:
A clip to be inserted into and fixed to a rectangular hole formed in an attached member includes: a base body portion that engages the rectangular hole on a one side of the attached member; a stem portion that extends from the base body portion to be insertable into the rectangular hole; and a pair of engaging legs that extend from an end portion of the stem portion toward the base body portion in an anchor leg-like manner. Engaging portions are disposed in ends of the engaging legs, respectively, to engage the rectangular hole on the other side of the attached member. Widths of the engaging legs are formed to be gradually enlarged from the end portion of the stem portion toward the base body portion, respectively.
Abstract:
An oil level gauge includes a handle section, a shank section, and a measuring section. The measuring section includes an upper limit mark and a lower limit mark in an up and down direction. The measuring section has a curved shape in a direction perpendicular to a longitudinal direction of the measuring section.
Abstract:
In this side lock apparatus, a opening and closing member is fixed to a support unit so that the opening and closing member can be opened and closed, left and right latches being movably held on the opening and closing member, the left and right latches being urged by a pressure of a spring toward a lock hole formed in the support unit, a free end portion of the latches being moved back from the lock hole in the support member against the spring means by an operation of the operating handle, wherein the left and right latches are operatively connected together via a link lever supported rotatably via a shaft on the opening and closing member, the operating handle being provided with an operating portion engageable with the latch, at least one latch being provided with two contact surfaces engageable with the operating portion of the operating handle.
