A cooling apparatus for an engine includes an oil warmer, an engine internal passage, a warmer passage, a water pump, and a thermostat. The warmer passage connects an outlet of the internal passage to an inlet of the internal passage. The thermostat regulates an amount of coolant that flows into the oil warmer. The thermostat includes a valve member, a body, and a plurality of types of wax. The thermostat determines a degree of opening of the valve member in accordance with amounts of expansion of the respective types of wax caused by melting of the respective types of wax. The types of wax include a first wax, which melts at a first temperature, and a second wax, which melts at a second temperature which is higher than the first temperature.

A vehicle heat exchanger includes a plurality of cup plates that are formed such that a first layered space into which a first heat carrier is introduced and a second layered space into which a second heat carrier is introduced are formed alternately between the plurality of cup plates when the plurality of plates are stacked. Peripheral end portions of the plurality of cup plates are fixed together in a liquid-tight manner. A distance in a stacking direction from a first cup plate that forms the first layered space to a second cup plate that forms the second layered space and a distance in the stacking direction from the second cup plate to the first cup plate are set to different distances, and end portions of outer wall portions of the cup plates are bent back so as to be apart from each other when the cup plates are stacked.

Vehicle heat exchanger

The present invention is to provide a thermo-valve which can be operated with no unnecessary work to fill fluid easily and without fail into a circuit having the fluid flow therethrough at the time of a high temperature range. The thermo-valve comprises a valve housing, and a center guide shaftmovable to assume a valve movement limitation position GPin which a valve memberis retained to a second operation position BPto open a specific port, and a valve movement allowance position in which the valve memberis allowed to displace, the center guide shaftand the valve housingallowing a bimetal ringto be disposed therebetween, and the bimetal ring being deformed to retain the center guide shaftto the valve movement limitation position GPat the initial stage until the temperature of oil in the valve housingfirstly reaches the high temperature range, and to release the center guide shaftfrom the valve movement limitation position GPwhen the temperature of the oil in the valve housingreaches the high temperature range.

An air cleaner unit includes a casing and a filter element disposed in the casing for filtering air to be introduced into an internal combustion engine of a vehicle. The casing includes a first case member and a second case member that are coupled to each other such that the filter element is housed in an element housing portion of the casing. The first case member has a hinge receiving portion, and the second case member has a hinge inserting portion. The hinge receiving portion and the hinge inserting portion are disposed under the element housing portion. The hinge receiving portion includes an engagement opening in which the hinge inserting portion is received such that the hinge receiving portion and the hinge inserting portion are connected in a hinge manner. The hinge receiving portion further includes a hinge receiving surface that extends from a vicinity of the engagement opening.

Air cleaner unit for internal combustion engine

An air cleaner unit for an internal combustion engine includes a casing and a filter element disposed in the casing. The casing includes a first case member having a first opening and a first sealing surface on a periphery of the first opening and a second case member having a second opening and a second sealing surface on a periphery of the second opening. The first case member and the second case member are coupled such that the first and second openings are opposed in a substantially horizontal direction of a vehicle. The filter element has a peripheral portion that is interposed between the first sealing surface and the second sealing surface. The first case member includes a side wall and a projection that projects from an inner surface of the side wall. The filter element is held in a substantially vertical position in the casing through the projection.

A resin molded component includes a flange having a through-hole. A concave portion is formed on the surface of the flange that faces the component on which the flange is fitted. Flows of a molten resin material meet each other at a meeting portion in a region around the through-hole during a molding process, and a weld line is formed at the meeting portion. The concave portion is formed upstream of the meeting portion at which the flows of the molten resin material meet each other, and in the vicinity of the through-hole. The thickness of the resin material in the bottom portion of the concave portion is greater than the thickness of the resin material in the thinnest portion of the wall of the concave portion.

Resin molded component

An indicator for a vehicle having an engine and a transmission, includes a main engine speed indicator for indicating a present engine speed of the engine, and an auxiliary engine speed indicator for indicating an engine speed given after a gear shift operation of the transmission and calculated based upon the present engine speed. According to the indicator, the engine speed given after the shift operation of the transmission can be prospectively recognized. The drivability thus can be enhanced.

Indicator for vehicle

In an air cleaner casing 10 including an upper casing 11 and a lower casing 12, a stopper mechanism is formed in the upper casing 11 and the lower casing 12 to prevent relative movement between the upper casing 11 and the lower casing 12 after assembly. The air cleaner casing 10 has a hinge pin 17 and a hinge retainer 18 for receiving the hinge pin 17 therein. The hinge retainer 18 has a lateral U-shaped cross section having opposed surfaces 18a and 18b, at least one of which is tapered.
