Abstract (en)

Inside a casing (10), a support member (20) is fastened, at the upstream side of the support member, a first electric type heat generating member (30a) is arranged, and at a downstream side of the support member, a second electric type heat generating member (30b) is arranged. Each heat generating member is provided with an outer tube and a strip-shaped heat generating element. Each outer tube is arranged in the casing so that its center axial line is parallel to a longitudinal axial line of the casing. Each heat generating element has two end parts which are fastened to an inner circumferential surface of the corresponding outer tube and an intermediate part which extends between the two end parts without being fastened to the corresponding outer tube. Each intermediate part is wound about a winding axial line which is parallel to the center axial line of the corresponding outer tube. Supporters are provided which run from the first heat generating member through the support member to the second heat generating member. The supporters are fastened to the intermediate part of the first heat generating member and the intermediate part of the second heat generating member, whereby the first heat generating member and the second heat generating member are supported by the support member via the supporters.
