The bracket includes a first plate and a second plate. The first plate has both end portions attached to the second plate, and the second plate has both end portions attached to the exhaust system part. A first space is defined between the first plate and the second plate, and a second space is defined between the second plate and the exhaust system part. Each of the first space and the second space has a first open end disposed on the vehicle front side, and has a second open end disposed on the vehicle rear side. The first plate, the first space, the second plate, and the second space are disposed between the support member and the exhaust system part.

An evaporation type burner which can attain light-up and stable combustion of fuel at an early stage by evenly distributing fuel supplied from a fuel supply part to an impregnation member (wick) inside the impregnation member should be provided includes an exudation prevention member having lower fuel permeability than that of the impregnation member in a surface region of the impregnation member opposite to a infiltration region, which is a surface region of the impregnation member where the fuel infiltrates from the fuel supply part into the impregnation member, across the impregnation member. Preferably, a part of the exudation prevention member is embedded inside of the impregnation member, and another part projects from a surface of the impregnation member. More preferably, the exudation prevention member is constituted as a part of the partition member disposed on a downstream side of the impregnation member in a combustion chamber.

A pipe bend die unit comprises a clamp member having a first groove part of half-circular cross section on an outer peripheral surface thereof with a fitting recess extending in a peripheral direction by a first predetermined length on a planar surface perpendicular to a rotary axis, and a counter pressure member having a second groove part of half-circular cross section formed on an outer peripheral surface thereof, and a fitting protrusion extending in a peripheral direction by a second predetermined length from a tip end portion of the second groove part. The fitting protrusion is positioned in the fitting recess so that the first and second groove parts are combined to form a pipe-receiving groove of half-circular cross section. The counter pressure member and the clamp member are hingedly connected to one another so as to be rotatable relative to each other about the rotary axis.

The present invention is directed to a method of producing a container such as a catalytic converter for holding a fragile substrate in a cylindrical housing with a shock absorbent member wrapped around the substrate, with an appropriate holding force determined on the basis of frictional force between the shock absorbent member and the one with the smaller coefficient of friction out of the substrate and the cylindrical housing. The method comprises the steps of (1) inserting the substrate with the shock absorbent member wrapped around the substrate, into the cylindrical housing loosely, (2) applying an axial load to the substrate so as to move the substrate along a longitudinal axis of the cylindrical housing by a predetermined distance, monitoring the axial load applied to the substrate, and (3) reducing a diameter of at least a part of the cylindrical housing with the substrate held therein along the longitudinal axis of the cylindrical housing, with the shock absorbent member being compressed, to such an extent that the axial load equals a predetermined value.

The present invention is directed to a method of producing a container for holding a columnar member in a cylindrical housing with a shock absorbent member wrapped around the columnar member. The method comprises the steps of (1) compressing at least a part of the absorbent member wrapped around the columnar member, by a pushing member in a radial direction toward the longitudinal axis, (2) measuring a pressure applied to the absorbent member by the pushing member, (3) measuring a distance between the axis of the columnar member and an end of the pushing member contacting the absorbent member, when the measured pressure substantially equals a predetermined target pressure, to provide a target radius, (4) inserting the columnar member and the absorbent member into the housing loosely, and (5) reducing a diameter of the housing along its longitudinal axis, with the absorbent member being compressed, to such an extent that the inner radius of the housing substantially equals the target radius, to hold the columnar member and the absorbent member compressed at the target pressure, in the housing.

A heat recovery structure includes a pipe portion, a heat exchanging portion and an actuator. The pipe portion is inclined such that a side face of the pipe portion faces a diagonally lower side, and is configured such that exhaust gas from an engine circulates through the pipe portion. The heat exchanging portion is configured to communicate with the pipe portion and to perform heat-exchange between a heat medium and the exhaust gas flowing into the heat exchanging portion from the pipe portion such that the exhaust gas thus subjected to the heat-exchange with the heat medium flows out to the pipe portion. The actuator is configured to operate a selector valve configured to switch between a state where the exhaust gas circulates through the pipe portion and a state where the exhaust gas circulates through the heat exchanging portion.
