摘要： Intake valve drive shaft and exhaust valve drive shaft are arranged in parallel to each other and provided with sprockets, respectively, for receiving engine rotation from a crank shaft. A rocker cam is swingably mounted on the intake valve drive shaft to push the intake valve, and connected mechanically by a link mechanism with the intake valve drive shaft. The axis of the intake valve drive shaft is offset from the axis of the intake valve to one side. The rocker cam includes a cam nose which projects to the other side of the axis of the intake valve when the intake valve is in the closed state.

摘要： In a magnetic recording and reproducing apparatus according to the related art, since positions of central points of radiuses of curvature of opposing arc portions of a guide groove are coincident with each other in the direction in which a movable chassis is moved, it is difficult to make the whole of the magnetic recording and reproducing apparatus become light in weight and small in size. A magnetic recording and reproducing apparatus includes a fixed chassis (24) to which a rotary head drum (25) is attached, a movable chassis (23) slidably supported to the fixed chassis (24), a cam gear (51) rotatably supported to the fixed chassis (24) or the movable chassis (23) and which has a cam pin (51a) and a cam plate (59) attached to the movable chassis (23) or the fixed chassis (24) and which has a guide groove (65) with which the cam pin (51a) is slidably engaged, wherein the cam pin (51a) is moved along the guide groove (65) as the cam gear (51) is rotated, whereby rotation operation of the cam pin (51a) is transformed into slide operation of the movable chassis (23) to make the movable chassis (23) come close to or come away the rotary head drum (25). The guide groove (65) includes an arc-like eject side slide portion (66) which is dented in the opposite side of the rotary head drum (25), an arc-like play side slide portion (67) which is dented in the side of the rotary head drum (25) and a slide portion (68) continued to one side of the eject side slide portion (66) and the play side slide portion (67) and which is extended in the direction substantially perpendicular to the direction in which the movable chassis (23) is moved, positions of central points of radiuses of curvature of the eject side slide portion (66) and the play side slide portion (67) being displaced in the direction perpendicular to the direction in which the movable chassis (23) is moved.
