Abstract
(EN)
In order to suppress shift in resonance frequency in a resonator, the present invention comprises: a vibrating unit having a base unit and a plurality of vibrating arms, said base unit having a front end and a rear end facing the front end and said plurality of vibrating arms extending in the direction away from the front end of the base unit and having a fixed end connected to said front end; a holding unit provided in at least part of the periphery of the vibrating unit; and a holding arm provided between the vibrating unit and the holding unit, having one end thereof connected to the base unit, and the other end thereof connected to an area in the holding unit that is further on the front end side than the rear end of the base unit.
(FR)
Afin de supprimer un décalage d’une fréquence de résonance dans un résonateur, la présente invention comprend : une unité de vibrations ayant une unité de base et une pluralité de bras vibrants, ladite unité de base ayant une extrémité avant et une extrémité arrière en regard de l’extrémité avant tandis que ladite pluralité des bras vibrants s’étendent dans la direction s’éloignant de l’extrémité avant de l’unité de base et ont une extrémité fixe connectée à ladite extrémité avant ; une unité de retenue disposée au moins en partie sur la périphérie de l’unité de vibrations ; et un bras de retenue disposé entre l’unité de vibrations et l’unité de retenue, dont une extrémité est connectée à l’unité de base et dont l’autre extrémité est connectée à une zone dans l’unité de retenue qui est davantage du côté de l’extrémité avant que l’extrémité arrière de l’unité de base.
