Abstract: A hydraulic chain tensioner is provided to prevent operational interruption by discharging easily residual air in an inside of a high pressure chamber of a plunger body in a starting state of an engine to the outside through an air ventilation line. A hydraulic chain tensioner includes an outer body, an inner body, a plunger body, a check valve, an air ventilation line, and a return spring. The outer body is inserted in a cylinder head. The inner body is mounted in the inside of the outer body. A low-pressure chamber for receiving oil is formed in the inside of the inner body. The plunger body is inserted into the cylinder head. The plunger body slides on an outer circumference of the inner body between the outer body and the inner body. The plunger body includes a high-pressure chamber connected to the low-pressure chamber. The check valve is installed in a connective path between the low-pressure chamber and the high-pressure chamber in order to suppress a counter current of oil from the high-pressure chamber to the low-pressure chamber. The air ventilation line is installed in the high-pressure chamber of the plunger body in order to generate elastic force as a retainer of the check valve. The return spring is formed to discharge the air from the inside of the high-pressure chamber to the outside between an installation side of the cylinder head and an outer circumference of the plunger body.

Abstract: PURPOSE: A holder for supporting a brush of an alternator is provided to induce a smooth perturbation between a brush and a latch fragment part by forming a protrusion part on a holder and forming a pin hole to fix the brush on the protrusion part. CONSTITUTION: A fixing pin(18) is formed to fix a brush(15). A pin hole(17a) is formed on a holder(17), into which the fixing pin(18) is inserted, whereby the brush(15) is fixed when a holder(17) is assembled with an alternator. The pin hole(17a) is formed on a protrusion part(17c). The protrusion part(17c) is protruded in an outward direction of the holder(17). A latch fragment part(17b) is generated in a circumference of the hole when the pin hole(17a) is formed. The brush(15) is moved to be protruded in an outward direction of the holder(17) after being assembled. An interference is prevented between the latch fragment part(17b) and a front end part of the brush, so that there is prevented a perturbation defect of the alternator due to a perturbation defect between the brush(15) and the latch fragment part(17b).
