End portions of first and second metal plates are overlapped with non-cured sealant interposed therebetween. Spot-welding is applied to the overlapped end portions to assure tight joining between the first and second metal plates. The joined metal plates are then coated with paint and put in an oven for not only drying the paint but also melting the sealant. During this drying process, the melted sealant flows into an entire clearance defined between the overlapped end portions of the first and second metal plates. The joined first and second metal plates are then cooled to solidify the sealant.

Method for joining two metal plates with sealant therebetween

A hose clamp which has an expanding portion of increased width at predetermined parts of a clamping portion is so formed as to produce a constant stress caused by the bending moment of forces and the axial force acting on the position where the maximum stress is applied to the clamping portion. The hose clamp has a first gripping end portion and a pair of second gripping end portions to expand the diameter of the clamping portion. Plastic deformation is prevented at the time of expanding the diameter of the clamping portion of the hose clamp.

The improved structure of a breather pipe for a gasoline tank comprises synthetic resin pipes constituting the straight portions of the breather pipe and connecting members constituting the bending portions of the breather pipe. The connecting members are molded of a synthetic resin and each comprise in integral combination a base, shoulder portions extended downwardly from the opposed sides of the base, internally communicating connecting arms formed as a whole in the shape of a letter 'V', 'U' or the like and disposed on the upper portion of the base, a zigzag arrangement keeping leg extended from the lower surface of the base through the medium of a reinforcing rib 17 and provided with projecting pawls which upwardly project outwardly from the lower end of the leg and which have at the leading ends thereof stepped portions being engaged with the edge of a hole bored in advance in a proper place of a given panel and being adapted to hold the panel in co-operation with the shoulder portions.
