摘要： PROBLEM TO BE SOLVED: To provide a mechanism in which a worker is prevented from forgetting the taking-off of a temporarily set bolt for temporarily setting a scissors gear at the time of assembling respective constitutional components.
SOLUTION: An idler gear 13 is constituted of a main gear 21, sub-gears 22, 23 installed relatively rotatably to the main gear, and springs 24, 25 for imparting a biassing force in the peripheral direction contradictory to each of the main gear and the sub-gear. The temporarily set bolt 37 is provided for temporarily setting both the main gear and the sub-gears in the state of tooth traces being in alignment with each other. The full length in which a protrusion shaft 37c is integrally provided at the head 37a of the temporarily set bolt is made longer than the distance between the idler gear and an oil pan. Thus, the tip end of the protrusion shaft 37c causes interference at the time of final assembly of the oil pan.

摘要： PROBLEM TO BE SOLVED: To provide a balancer device capable of preventing relative rotations between an intermediate gear and a balancer gear which can be standardized for each device size without increasing the delivery package size. SOLUTION: The balancer device 5 comprises the intermediate gear 11, which is rotatably supported by a boss member protruded on one side surface of an upper housing 6 and is engaged with a crank gear 4 fixed on one end part of a crankshaft 2, and the balancer gear 12, which is fixed on one end of a drive shaft 8 rotatably supported by the upper housing 6 and lower housing 7. The intermediate gear 11 further comprises a regulating member 30 covering a predetermined area of the tooth part of the intermediate gear 11 in a circumferential direction as an attachment, so as to regulate relative rotations between both gears 11, 12 by limiting the mutual engagement of the gears 11, 12 with the attached regulating member 30.

摘要： PROBLEM TO BE SOLVED: To reduce the spring constant fluctuation of a tooth by the working position and to decrease the working vibration.
SOLUTION: In at least either one of a driving gear and a driven gear, the tooth depth is changed along the tooth trace so that the overall contact ratio becomes substantially an integer. or, the tooth depth is gradually decreased along the tooth trace toward the end of the tooth thereby allowing the tooth tip ridge line of the section where the tooth depth gradually decreases to approximately parallel with the simultaneous contact line, or, the tooth depth is changed along the tooth trace so that the change of the total of the lengths of the simultaneous contact lines accompanying the progress of engagement is minimized, or, the tooth depth is changed along the tooth trace, and the contact ratio is set to be approximately 2 or 3 in a first area where the tooth depth is short, whereas in a second area where the tooth depth is larger the contact ratio is set to be larger than that of the first area and the spring constant of the tooth is approximately equalized to the spring constant of the tooth in the first area.
