要約
(EN)
The purpose of the present invention is to provide a mechanical lash adjuster in which a retention mechanism for retaining a plunger in a housing is inexpensive. A lash adjuster (1) is provided with: a housing (3) having a closed-end cylindrical shape; a plunger (2) held within the housing (3) while the outer peripheral surface (9) of the plunger inscribes the inner peripheral surface (10) of the housing (3); and a retention mechanism (14) for preventing the plunger (2) from coming out of the housing. The retention mechanism (14) is provided with: a first groove (11) formed in the inner peripheral surface (10) of the housing (3) so as to extend in the circumferential direction of the inner peripheral surface (10); a second groove (12) formed in the outer peripheral surface (9) of the plunger (2) so as to extend in the circumferential direction of the outer peripheral surface (9) and so as to be located facing the first groove (11); and a flexible wire material (4) inserted into both the first groove (11) and the second groove (12).

La présente invention vise à proposer un dispositif mécanique de rattrapage de jeu muni d'un mécanisme de retenue peu coûteux retenant un piston dans un carter. Le dispositif de rattrapage de jeu (1) comprend : un carter (3) de forme cylindrique à extrémité fermée; un piston (2) maintenu à l'intérieur du carter (3), la surface périphérique extérieure (9) du piston entourant la surface périphérique intérieure (10) du carter (3); et un mécanisme de retenue (14) qui empêche le piston (2) de sortir du carter. Le mécanisme de retenue (14) comprend : une première rainure (11) formée dans la surface périphérique intérieure (10) du carter (3) de manière à s'étendre dans la direction circonférentielle de la surface périphérique intérieure (10) : une seconde rainure (12) formée dans la surface périphérique extérieure (9) du piston (2) de manière à s'étendre dans la direction circonférentielle de la surface périphérique extérieure (9) et à se trouver face à la première rainure (11); et un matériau en fil flexible (4) inséré à la fois dans la première rainure (11) et dans la seconde rainure (12).
