摘要： PROBLEM TO BE SOLVED: To provide an apparatus for preventing dew drops which has enough strength to prevent the falling of a case main body even when a blow molding method is used for manufacture, and has a small number of assembling parts. SOLUTION: Reinforcing ribs 15 are molded integrally in the inside wall close to the opening part of the case main body 10. Zigzag passage partition walls 11, 12, and 13 formed in the case main body 10 are formed by making the tip parts of partition wall constituent pieces 111, 121, and 131 of a pair which are molded integrally on both opposite side walls 10a of the case main body 10 butt each other. The partition wall 11, below which dew drops passes, is formed so that each of its partition wall constituent pieces 111 of a pair is lowered from the protruding base end part 111b toward the protruding tip part 111a. Therefore, a ventilation space is formed above the partition wall 11, and the protruding base end part 111b is formed integrally in sequence to the reinforcing ribs 15.

摘要： PROBLEM TO BE SOLVED: To provide combustion equipment, in which setup of burner-port parts is facilitated, and fuel-gas leakage hardly occurs by improving kerosene-burning equipment having a constitution of burner-ports distributed in a planar shape. SOLUTION: The part of burner ports is constituted of a burner-port base 200, a network member 201, a burner-port member 202, and a flame-holder 203. In the burner-port base 200, channel-like opening 210 for releasing gas, and channel-like opening 211 for releasing secondary air are alternately provided. The network member 201 and the burner-port member 202 respectively have the same area as the base 200. Protrusions 213 are provided in the burner-port base 200. Fitting holes 214 and 222 are provided in the network member 201 and burner port member 202. The network member 201 and the burner-port member 202 are fit to each other by inserting the protrusions 213 on the base 200 into the holes 214 and 222, and caulking the protrusions 213.

摘要： PROBLEM TO BE SOLVED: To provide a bath tub coupling device for forced circulation which is simple in cleaning and removal of a filter member. SOLUTION: In the bath tub coupling device 1 for forced circulation, a device having a number of holes 35 formed in a single plate body is employed as a filter member 8. The filter member 8 is formed that a part to filter water and other part are positioned flush with each other. Since there is no extreme step, the step is not filled with dust. The filter member 8 employed for this invention has a protrusion 36 formed on the inner surface of a peripheral wall part. A body member 3 has a head part 20 having a front part and a peripheral surface part approximately in the same shape as that of the filter member 8, and the filter member 8 is mounted with a head part 20 of the body member 3 covered thereby. Further, a longitudinal groove 23 extending in an axial direction from the front part side and a peripherally extending lateral groove 25 linked to the longitudinal groove are formed in the peripheral surface part of a head part 20 of the body member 3, and the protrusion 36 of the filter member 8 is engaged with a groove 22.

摘要： PROBLEM TO BE SOLVED: To provide a circulation adaptor for a bath boiler with excellent durability which accurately realizes proper mounting workability and stable state of mounting without demand for strict dimensional accuracy as to the adaptor head and a filter member. SOLUTION: The circulation adaptor is provided with the body of the adaptor mounted on a bathtub and a filter member 20 detachably mounted on the body of the adaptor. The body 10 of the adaptor has an adaptor head 12 with a suction port and a discharge port formed thereon. A plurality of protruded parts 23 projecting inward are provided on the inner circumferential surface of the filter member 20 and first and second guide grooves 13 and 14 are formed in the outer circumferential surface of the adaptor head 12 to guide the protruded parts 23 to specified positions when the filter member 20 is mounted on the adaptor head 12 while a leaf spring 15 having a retaining protruded part 15a is mounted in a free state on the second guide groove 14 where the protruded parts 23 can slide over the protruded part 15a by forcing to deform the protruded part 15a elastically.
