摘要： PROBLEM TO BE SOLVED: To provide a traffic controlling barricade capable of being easily set and removed and having no bulky package when it is conveyed. SOLUTION: A plurality of barricade plates 1 are monolithically connected with joint members 3 consisting of two links 2 connected with pin joint, and an interval between the barricade plates 1 can be expansible in an accordion state. By the constitution, a space between the barricade plates 1 is enlarged to make it possible to set a barricade in a traffic controlling area of a road 9 within a short period of time, and when it is removed, the space between the barricade plates 1 is compactly contracted to make it possible to easily convy the barricade even in a narrow space.

摘要： PROBLEM TO BE SOLVED: To easily correct a change with a lapse of time in the elasticity of springs expanded/contracted at the time of opening/closing an original cover plate, even if the change with the lapse of time occurs, in an original cover plate opening/closing device having a lift support. SOLUTION: When the opening/closing operations of the original cover plate 4 are executed in a great number of times, the springs S1-S3 are gradually exhausted because they are expanded/contracted in a great number of times, so that the elasticity in the beginning can not be obtained. In such a case, in a state where the original cover plate 4 is opened, a wrench is inserted through an operation hole 38, to turn a nut 44 and move a spring tray 45 upward. Thus, the stroke of the spring S2 is made shorter than that until then, to recover the elasticity.

摘要： PROBLEM TO BE SOLVED: To absorb all directional vibrations, enhance the freedom in positioning of a plurality of exhaust paths, and allow an inexpensive manufacture. SOLUTION: Each exhaust path 20 of a dual vibration interrupting pipe 10 is formed of an upstream pipe 21 and a downstream pipe 22 which are mutually connected by an interlock 3. An interlock 3 displaces in the pipe axial direction to receive a tensile load and a compression load, or displaces in the pipe bending direction to receive a bending load, and it is formed of a circularly wound strip body 30. Since adjacent strip bodies 30 keep the mutual contact state even when the interlock 3 is extended in the pipe axial direction or bent in the pipe bending direction, the airtightness of each exhaust path 20 can be held. A bellows pipe 11 is formed of a bellows cylindrical pipe arranged so as to cover the part of the interlocks 3, 3 of two exhaust paths 20, 20, which is bendable in the bending direction or expansible in the axial direction.

摘要： PURPOSE: To enhance an interference effect between an exhaust noise and a cancel sound with simple constitution. CONSTITUTION: An opening surface having a slope in a noise exit of an exhaust pipe 1 and a cancel pipe 4 arranged apart from and in parallel to the exhaust pipe 1, guiding the cancel sound and of which opening surface having the slope faces to the former opening surface in a cancel sound exit are provided in the structure of an actuator for an electronic muffler forming the cancel sound canceling a noise from the exhaust pipe 1 of a vehicle. A muffler cutter 5 surrounds along in the directions of the noise exit of the exhaust pipe 1 and the cancel sound exit of the cancel pipe 4 and forms a fixed space. The muffler cutter 5 is fixed to the cancel pipe 4 by a fixing bolt 6. A heat insulating spacer is provided between the exhaust pipe 1 and the muffler cutter 5. The cancel pipe 4 and the muffler cutter 5 are fixed by a fixing plate 11 together with the fixing bolt 6. The tip part of the opening surface of the exhaust pipe 1 and the tip part of the opening part of the cancel pipe 4 are not made an acute angle but made a surface.

摘要： PURPOSE:To provide sufficient seal properties, and to enable connection to be easily released after the connection. CONSTITUTION:A joint structure 10 for pipes is composed of first and second pipes 1, 2 and a clamp 3. First and second curl parts 1a, 2a are formed on the first and second pipes 1, 2 and faced to each other. A circumferential groove 5 provided on the clamp 3 is composed of first and second groove formed surfaces 5a, 5b whose distance is narrowed outward in the radial direction from the inner peripheral side. When a bolt of the clamp 3 is tightened, the first curl part 1a is pressed to the second curl part 2a side by the first groove formed part 5a, and the second curl part 2a is pressed to the first curl part 1a side by the second groove formed surface 5b, thereby both curl parts 1a, 2a are brought in strong-contact with each other, and adhesiveness and seal properties are improved. When the bolt of the clamp 3 is loosened, the first and second pipes 1, 2 are easily separated from each other.

摘要： PURPOSE:To prevent the condensation of a blow-by gas in a bending reflux pipe owing to a temperature drop effectively by penetrating at least one line of inner pipe in a large diameter outer pipe, letting flow an engine cooling water in the outer pipe, while letting flow a blow-by gas in the inner pipe. CONSTITUTION:In a blow-by gas reflux pipe to recirculate a blow-by gas leaked in a crankcase to an engine suction pipe, a small diameter of inner pipe 2 bending in the same form as an outer pipe 1 is inserted to a larger diameter of bending outer pipe 1. While a blow-by gas is let flow in the inner pipe 2, a high temperature of engine cooling water is let flow in the peripheral outer pipe 1. The middle parts of the inner pipe 2 and the outer pipe 1 other than their ends are not necessary to contact in particular, but they may be laser welded at an adequate position. By such a constitution, a temperature drop of the blow-by gas flowing through the inner pipe 2 is prevented effectively.

摘要： PURPOSE:To improve the working performance in the bending work and reduce the number of part items. CONSTITUTION:An outer pipe 22 is externally fitted on an inner pipe 12 having a bellows part 14. The inner surface of the outer pipe 22 and the top part of the bellows part 14 are closely attached substantially, and a gap having the width corresponding to the difference between the top diameter and the bottom diameter of the bellows part 14 is secured between the inner pipe 12 and the outer pipe 22. In the bending work, the bellows part 14 operates as core metal for the outer pipe 22, and the generation of the trouble such as the sinking into the bent part of the outer opip 22 is prevented. Further, since the bellows part 14 possesses the small bending resistance, it can be bent speedily and in good order according to the bending of the outer pipe 22. Accordingly, the bending work performance is improved drastically. Further, since the bellows part 14 operates as a member for absorbing the thermal expansion difference between the inner pipe 12 and the outer pipe 22, the quantity of parts can be reduced.
