The first rotating shaft portion 231 is coupled to the inner ring, and the second rotating shaft portion 233 is coupled to the outer ring. The uni-directional bearing portion 236 includes an outer ring, an inner ring, and a roller.

The unidirectional bearing portion 236 is fixed between the outer ring and the inner ring so that the outer ring and the inner ring are fixed, so that rotational force is transmitted from the first rotating shaft portion 231 to the second rotating shaft portion 233. However, since the roller rotates freely during the reverse rotation, rotational force is not transmitted from the first rotary shaft portion 231 to the second rotary shaft portion 233.

Therefore, the intermittent clutch 235 operates to rotate the second rotary shaft portion 233 are fixed to prevent rotation.

The operation of the exercise device according to one embodiment of the present invention will now be described.

When the motor 410 of the driving unit 400 rotates in the normal direction, the gear unit 420 changes the rotation center direction of the rotational force generated by the motor to a right angle, and transmits the rotational angle to the first rotating shaft unit 231. The first rotating shaft portion 231 is rotated forward by receiving the rotational force from the gear portion 420 and the unilateral bearing portion 236 is rotated forward to transmit rotational force to the second rotating shaft portion 233. [ When the second rotary shaft portion 233 rotates, the eccentric pin 232a of the second rotary shaft portion eccentrically rotates. The eccentric pin 232a of the second rotary shaft portion 233 and the first motion shaft portion 234 coupled by the universal joint reciprocate as the eccentric pin is rotated eccentrically. Since the first motion shaft portion 234 is coupled to the support portion 110 by a universal joint and the first motion body 210 is coupled to the support portion 110 by the first engagement portion 220, As shown in Fig.

When the motor 410 of the driving unit 400 rotates in the reverse direction, the gear unit 420 changes the rotational center direction of the rotational force generated by the motor to a right angle and transmits the same to the first rotating shaft unit 231. The first rotary shaft portion 231 receives the rotational force from the gear portion 420 and rotates in the reverse direction and the unilateral bearing portion 236 rotates in the reverse direction and can not transmit the rotational force to the second rotary shaft portion 233. When the first rotating shaft 231 rotates in the reverse direction, the interrupted clutch 235 fixes the second rotating shaft 233 to prevent the second rotating shaft from rotating. Therefore, the first body of motion does not reciprocate in the lateral direction.

The eccentric wheel portion 332 receives the rotational force from the gear portion 420 and rotates eccentrically regardless of the rotational direction of the motor 410. The second motion shaft portion 334 is rotationally engaged with the eccentric wheel portion 332 to convert the rotational motion into the reciprocating motion. The second movement shaft portion 334 is fixedly coupled to the second movement body 310 and the second movement body 310 is coupled to the first movement body 210 by the second coupling portion 320, So that the second exercise body reciprocates in the forward and backward directions.

A variable eccentric portion 238 is provided at one end of the rotary shaft portion 232.

The degree of eccentricity of the variable eccentric portion 238 varies in accordance with the rotation direction of the rotary shaft portion 232. [ The degree of eccentricity of the variable eccentric portion 238 from the center of the rotary shaft portion during the forward rotation 230A of the rotary shaft portion 232 becomes large and the degree of eccentricity from the center of the rotary shaft portion becomes small at the variable eccentric portion during the reverse rotation 230B of the rotary shaft portion.

The variable eccentric portion 238 is rotationally coupled with the first motion shaft portion 234 to convert rotational motion into reciprocating motion. The magnitude of the reciprocating motion to be varied is varied according to the rotating direction of the rotating shaft portion 232.

One end of the first motion shaft portion 234 is rotationally coupled with the variable eccentric portion 238. One end of the first motion shaft portion 234 is preferably coupled to the variable eccentric portion 238 by a universal joint. The other end of the first motion shaft portion 234 is rotationally coupled with the support portion 110. The other end of the first motion shaft 234 is preferably coupled to the support 110 by a universal joint.

The rotary shaft portion 232 receives the rotational force from the gear portion 420 and is rotated forward. The variable eccentric portion 238 is eccentrically rotated in a state where the degree of eccentricity is large from the center of the rotary shaft portion. The first eccentric shaft portion 234 coupled to the variable eccentric portion 238 by a universal joint largely reciprocates. Since the first motion shaft portion 234 is coupled to the support portion 110 by a universal joint and the first motion body 210 is coupled to the support portion 110 by the first engagement portion 220, And a large reciprocating motion is performed in the direction.

When the motor 410 of the driving unit 400 rotates in the reverse direction, the gear unit 420 changes the rotation center direction of the rotational force generated by the motor to a right angle, and transmits the rotational force to the rotating shaft unit 232. The rotary shaft portion 232 receives the rotational force from the gear portion 420 and rotates in the reverse direction. The variable eccentric portion 238 eccentrically rotates with a small eccentricity from the center of the rotary shaft portion. The first motion shaft portion 234 coupled with the variable eccentric portion 238 by the universal joint makes a small reciprocating motion. Since the first motion shaft portion 234 is coupled to the support portion 110 by a universal joint and the first motion body 210 is coupled to the support portion 110 by the first engagement portion 220, Thereby making the reciprocating motion small.

The eccentric wheel portion 332 receives the rotational force from the gear portion 420 and rotates eccentrically regardless of the rotational direction of the motor 410. The second motion shaft portion 334 is rotationally engaged with the eccentric wheel portion 332 to convert the rotational motion into the reciprocating motion. The second movement shaft portion 334 is fixedly coupled to the second movement body 310 and the second movement body 310 is coupled to the first movement body 210 by the second coupling portion 320, So that the second moving body reciprocates in the front-rear direction.
