摘要： PROBLEM TO BE SOLVED: To disable falling-off of a locking member from an installation hole by forming an installation hole perpendicularly to the installation hole of the locking member on a handle, and press-fitting a stopper of the locking member to it. SOLUTION: An installation hole 36 penetrates to a lower side of an installation hole 35 of a lock pin 42. The installation hole 36 is formed perpendicularly to the installation hole 35, and crosses the hole 35 at its upper side in an intermediate portion in the longitudinal direction. A split is formed on an outer peripheral surface of a cylindrical body of a spring pin 43 from one to another end. The pin 43 is press-fitted to the installation hole 36 due to elasticity. An upper certain portion on an outer periphery of the pin 43 is projected into the installation hole 35 at an intersection, and arranged into a position regulation recession 42b of the lock pin 42. The pin 43 is abutted against a side surface on a leading end side of the position regulation recession 42b when the lock pin 42 is moved to the outside by means of a coil spring 41, for preventing the lock pin 42 from further moving to the outside. It is thus possible to prevent the lock pin 42 from falling off to the outside from the installation hole 35.

摘要： PURPOSE: To dispense with a stopping ring and facilitate assembling of an intermediate member in a gas plug having an energizing member, by forming an abutting surface on an inner peripheral surface near an opening of a plug housing port so as to extend in a circumferential direction, and forming a plurality of insertion grooves reaching the abutting surface from the opening side of the plug housing port. CONSTITUTION: A gas plug A has an intermediate member 3 inside a plug housing port 15 having a tapered port 15a, and a pressing spring 6 which energizes a plug body 2. An abutting surface 15e is formed on an inner peripheral surface near an opening of the plug housing port 15, which surface 15e is directed to the tapered port 15a and extends in a circumferential direction. A plurality of insertion grooves 15d are formed so as to communicate an opening side of the plug housing port 15 with the abutting surface 15e. An engagement projection 31 of the intermediate member 3 are aligned so as to oppose to the insertion groove 15d, and then the intermediate member 3 is fitted to the plug housing port 15. When the engagement projection 31 passes the groove 15d, the intermediate member 3 is rotated and the engagement projection 31 is opposed to the abutting surface 15e for completing installation.

摘要： PURPOSE:To reduce the labor required for connection of flexible tube to a fitting which includes a fitting main body fastening member and a pair of retainers whereby pushing the flexible tube for connection, by holding a pair of the retainers and providing a retainer holding body and a resilient member. CONSTITUTION:A fitting A includes a fitting main body 1, cap nut (fastening member) 2, a pair of retainers 3, 4, a retainer holding body 5 and a spring 6. A fitting main body 1 is formed with a connecting hole 13, and the cap nut 2 is formed with a through-hole 20 at the central portion thereof. The through- hole 20 is constituted of a guide hole 21 having a diameter larger than that of a flexible tube P. Each of the retainers 3 and 4 is formed in a half-cylinder shape and is formed in a bellows-shape on its inter peripheral surface. The retainer holding body 5 includes a cylindrical portion 50 having the inside diameter almost similar to the outside diameter of an annular projection 18 of the fitting main body 1. The retainers 3 and 4 are respectively energized in the mutually approaching direction by the spring 6. As a result, the flexible tube can be connected to the fitting by inserting the flexible tube in the connecting hole thereby fastening it by the fastening member.

摘要： PROBLEM TO BE SOLVED: To eliminate movable members, and try to reduce manufacturing cost by forming as escape part in the outer circumferential surface of a locking member to be inserted into a mounting hole, and also forming a screw part in the aforesaid locking member, which permits the locking member to be moved to a locking position by letting the locking member to be threadeclly engaged with a screw hole part formed in the inner circumferential surface of the mounting hole. SOLUTION: In the gas plug closed condition where the handle part 3a of a handle 3 is directed to the direction perpendicularly intersected with a gas passage, in order to open the plug, let a lock pin 42 be moved against a coil spring 41 inward to a position where its base end face roughly coincides with the opening periphery of a mounting hole 35. In this case, an engaging wall part 14 can pass through an escape groove 42a, and the handle 3 can thereby be revolved with respect to a plug main body. And when the plug is closed, after the lock pin 42 has been furthermore pushed in, when its screw part 42d is screwed in the screw hole part 35a of the mounting hole 35 so as to allow the side surface at the base end side of a position regulating recessed part 42b to be knocked against a spring pin 43, an abutting part 42c is thereby positioned in an identical circumference to the engaging wall part 14, the handle 3 is thereby brought into a condition where the handle can not be functionally revolved.

摘要： PURPOSE:To prevent leakage of gas by making a difference in pressure receiving area between the separating direction of a valve element of a gas cut-off device and the seating direction thereof, so that when a cock of a gas appliance is opened, the valve element keeps seating. CONSTITUTION:A valve seat 10 having a communicating path 12 directing to the inflow side portion 3 is formed on an apparatus body 1. A valve element 17 is urged towards the valve seat 10. The valve element 17 is formed in such a manner that at the time of seating, an area where gas pressure is applied in the separating direction is larger than that in the seating direction. In this arrangement, if a cock of a gas appliance disposed on the outflow path 4 side is closed, the inflow side and the outflow side become the same pressure, so that the valve element 17 is put in the state of separating from the valve seat by a difference in pressure receiving area. When the gas cock is opened, the pressure on the outflow side 4 will not be increased so that the valve element 17 keeps seating.
