PROBLEM TO BE SOLVED: To provide a vibration generating apparatus capable of achieving both of acceleration of the vibrating generation apparatus and reduction in the manufacturing cost.SOLUTION: A vibration generating apparatus includes a first vibration generating piston 21, a first advancing operation chamber 13a, a first retreating operation chamber 13b, and switching means for alternately guiding high pressure oil into the first advancing operation chamber 13a and the first retreating operation chamber 13b. The switching means includes a second cylinder housing 12 having a second cylinder hole 12a arranged in parallel with a first cylinder hole 11a, a second vibration generating piston 22 stored in the second cylinder hole 12a so as to be advanced and retreated by following the advancing and retreating movement of the first vibration generating piston 21, a second advancing operation chamber 14a, and a second retreating operation chamber 14b. A relief mechanism 30 capable of discharging the high pressure oil from one of the second advancing operation chamber 14a and the second retreating operation chamber 14b when the first vibration generating piston 21 and the second vibration generating piston 22 are in the neutral state is provided in the second vibration generating piston 22.
【課題】振動発生装置の高速化と製造コストの低廉化とを両立することができる振動発生装置を提供する。【解決手段】第１起振ピストン２１と、第１前進用作動室１３ａと、第１後退用作動室１３ｂと、高圧油を第１前進用作動室１３ａと第１後退用作動室１３ｂとに交互に導く切替手段とを備え、切替手段が、第１シリンダ孔１１ａに並列状に配設された第２シリンダ孔１２ａを有する第２シリンダハウジング１２と、第１起振ピストン２１の進退移動に追従して第２シリンダ孔１２ａに進退移動可能に収容された第２起振ピストン２２と、第２前進用作動室１４ａと、第２後退用作動室１４ｂとを備え、第１起振ピストン２１と第２起振ピストン２２とが中立状態のとき、第２前進用作動室１４ａと第２後退用作動室１４ｂのうち一方から高圧油を排出可能なリリーフ機構３０を第２起振ピストン２２内に設けた。【選択図】 図３
