FIG. 9 shows an example of the engine mount.
In the figure, reference numeral 1 denotes a holding body, which consists of a cylindrical holding part 11 and a bracket part 12 provided on the lower surface thereof, and is fixed to a vehicle frame (not shown) through a mounting hole 121 of the bracket part 12. A vibration-proof rubber body 2 having parallel side surfaces is press-fitted into the holding body 1 and radially traverses it, and a pipe-shaped engine connecting member 3 is inserted through the center of the rubber body 2. It has been done.
防振ゴム体2は水平面と角度θを成して配設さ

ともにこれに直交する方向にはバネ定数は低い。 The vibration isolating rubber body 2 is disposed at an angle θ with the horizontal plane, and has a high spring constant in this direction, and a low spring constant in the direction orthogonal thereto.
したがつて、上記直交方向より入力する高周波
振動は効果的に吸収される。 Therefore, high frequency vibrations input from the orthogonal direction are effectively absorbed.

By the way, the above-mentioned press-fit type engine mount has the advantage of being simple in structure and easy to manufacture.
Rubber body 2 becomes holder 1 due to repeated vibrations.
In such a case, the vibration input in the orthogonal direction will not be absorbed, resulting in a problem.

The structure of the present invention will be explained with reference to FIG. 1. A holder 1 fixed to a vehicle frame is a cylinder having a smooth circular outer circumferential surface with a constant diameter and a circular inner circumferential surface with a smaller diameter. The inner circumferential surface is provided with convex portions 13 that protrude radially inward or recesses that recess radially outward at at least two radially symmetrical positions in the circumferential direction. The plate-shaped vibration isolating rubber body 2 has an engine connecting member 3 penetrating through the center thereof, and has recesses 21 or protrusions formed on both end faces, and these recesses 21 or protrusions are connected to the protrusions 13 or 13 on the circumferential surface of the holder. The vibration isolating rubber body 2 is fixed within the holder 1 so as to cross the interior of the holder 1 at a predetermined angle by being press-fitted into the recess.

Since the convex portion 13 and the concave portion 21 are firmly fitted together, the vibration isolating rubber body 2 does not rotate relative to each other due to vibration input, and engine vibration is always inputted from the direction orthogonal to the side surface of the vibration isolating rubber body 2. absorption is effectively reduced. Furthermore, since the holder 1 has a smooth circular outer circumferential surface with a constant diameter, the holder 1 has sufficient strength against collisions with foreign objects and can prevent the adhesion and accumulation of dust and the like.

The holding body 1 shown in FIG. 2 consists of a cylindrical holding part 11 and a bracket part 12 provided on the lower surface of the holding part 11, and is fixed to a vehicle frame through a mounting hole 121 of the bracket part 12. Convex portions 13 are formed on the inner circumferential surface of the holding portion 11 by joining metal rods each having a semicircular cross section at radially symmetrical positions.
It is as follows. One of the protrusions 13 is positioned upward, and the other is positioned downward, and a line connecting these is inclined by a predetermined angle θ with respect to the horizontal line.

The vibration isolating rubber body 2 is made of a thick rubber plate with parallel sides, and has a pipe-shaped engine connecting member 3 extending through the center thereof. The upper and lower end surfaces 2a of the rubber body 2 are curved outward in an arc shape, and a groove with a semicircular cross section is formed in the center to form a recess 21.

回動は阻止され、位置ずれが防止される。 Therefore, the vibration isolating rubber body 2 has each concave portion 21,
It is press-fitted into the holder 1 in alignment with each convex portion 13 of the holder 1. This is shown in FIG. According to this structure, the convex portion 13 and the concave portion 21 are firmly fitted to each other, thereby preventing relative rotation of the rubber body 2 and preventing positional displacement.

According to this embodiment, since the convex portions 13 and the concave portions 21 are fitted together at four corner portions of the vibration isolating rubber body 2, displacement in the circumferential direction can be more effectively prevented. In addition, in this embodiment, a ring-shaped spacer 14 is press-fitted into the holding part 11 in contact with the outer periphery of the front and rear surfaces of the vibration-isolating rubber body 2, thereby also preventing displacement of the vibration-isolating rubber body 2 in the axial direction. are doing.
